In order to evaluate the effectiveness of the corrosion prevention practices applied to agricultural equipment manufactured and used in Nigeria, it is necessary to identify the various corrosion prevention methods and specify the contribution and the efficiency of each method to corrosion protection. This paper outlines the basic corrosion prevention methods used in practice and attempts to evaluate the effectiveness of their use in relation to agricultural service in Nigeria. The results of this study indicated the use of oils, fats, waxes and lubricants on metal parts, spraying with gasoline on corrosion‐sensitive parts constituted the majority of applied corrosion protection in industries where the equipment is manufactured and/or used. The study concluded by giving practical recommendations that are essential for improving corrosion prevention in the Nigerian agricultural industry.

Because of the peculiar nature of food and agro‐processing industries, the industries cannot tolerate corrosion deposits in their production lines. Hence, there is the need to account for corrosion control before and during the production operations. This is more so in Nigeria where there is little or no proper accountability of corrosion cost in all production system.

The industries investigated were grouped into: meat and meat product, dairy and milk, beverages and brewery, confectionery and agro‐processing centres. Questionnaires and interview pro forma were used to collect information from ten major factories/outlets in each category. The study involved the use of life cycle costing to assess corrosion management alternatives and to determine the annualized value of each option.

Among the corrosion prevention methods identified in the industries, greasing gave the least cost contribution (15.9 percent) to the total cost of corrosion prevention followed by painting (17.97 percent) and cleaning (66.14 percent) in that order, while the contribution of each corrosion maintenance method to the total cost of corrosion maintenance was, respectively, 13.08, 7.23, 20.73 and 58.96 percent for annual maintenance, repair, rehabilitation and wages of workers.

This study reveals some of the control measures commonly adopted for minimizing corrosion damage in some selected food and agro‐processing industries in Nigeria. It also investigated the cost implication of each measure and how it affects the present value of processing machineries in each industry. The results of the study have created a state of awareness of corrosion problems to stakeholders, which would encourage preventive actions.

In the past, the RAF’s approach to corrosion was reactive: corrosion occurred, was identified and then rectified. Such a strategy is no longer acceptable, as corrosion rectification is costly both in terms of material and aircraft availability. More importantly, as escalating replacement costs force us to retain aircraft in service for ever‐longer periods, the threat posed to structural integrity by corrosion and repeated corrosion repairs can no longer be tolerated. Consequently, the RAF has had no option but to develop a policy of corrosion prevention. Aerospace Maintenance, Development and Support, part of Headquarters Royal Air Force Logistics Command, has therefore been actively involved with the evaluation and trialling of a range of important corrosion prevention techniques that are compatible with the RAF’s current stance. Aircraft washing and rinsing practices have been reviewed to confirm their effectiveness, and trials have shown that dehumidified air permeates readily through a full‐size airframe, reducing relative humidity and arresting the rate of corrosion. From our work we have concluded that effective washing should be supported, where possible, by freshwater rinsing, and, if a cost effective system can be developed, structural dehumidification should also be practised. Notwithstanding a policy of corrosion prevention, we know that we operate aircraft that have already accumulated corrosion damage which has to be located and recorded. Non‐destructive testing is employed widely, and the use of information derived from the process to populate structural databases is being explored. Additionally, we are involved with refining the methodologies associated with structural inspections to ensure the ongoing integrity of our ageing aircraft fleets.

The purpose of this paper is to obtain a better insight into the impact of atmospheric corrosion in Mauritius by investigating the corrosion prevention strategies used in the country and determining the related costs.

Companies and organizations, in various industrial sectors, affected by atmospheric corrosion were selected. They were inspected and surveys were performed in order to fulfill the aim of the study.

It has been observed that extensive atmospheric corrosion problems have been encountered in the capital city, leading to the use of a range of corrosion prevention methods. However, carbon steel, which corrodes easily, is very commonly used in the country. This leads to the wide use of alkyd‐based barrier coatings. The cost of atmospheric corrosion has been found to be equal to 0.38 per cent of the GDP.

This study is expected to raise concern on the problem of atmospheric corrosion in Mauritius and the related waste in materials.

This study is expected to help in adopting corrosion prevention policies and strategies in Mauritius.

Discusses the need for structural maintenance programmes to check the airworthiness of planes and detect damage. Describes the prevention and control of corrosion along with its causes, and examines aviation safety assurance programmes.

The industrial expansion of the post‐war period has resulted in the development of new products and processes, specialised equipment and new materials of construction. Materials science, technology and engineering, has emerged as an independent discipline during the last decade. These changes have brought up the importance of corrosion problems and the urgency to apply preventive methods. It is probably true to say at the present time that the losses due to metallic corrosion give a fair index of the industrial prosperity of a nation. A developing country like India had to face the challenge posed by corrosion, and there is now an increasing awareness of the imperative need for corrosion research and the application of the findings to meet specific situations.

The purpose of this paper is to objectively evaluate the cost benefit of applying corrosion prevention coatings throughout a mid-life logistics fleet supporting the Canadian Army.

A database of maintenance records for an Army logistics vehicle throughout a four-year study period is mined. Statistical analysis (primarily ANOVA) accounting for the frequency of treatment and geographic region is executed.

Statistical analysis indicates counter-intuitive results. Vehicles that are most frequently treated to prevent corrosion incur the highest maintenance costs. Consultation with operational units suggests that a strategic approach to corrosion prevention is largely absent. Instead, vehicles are treated on an ad hoc basis, or – equivalently – on an as available basis.

Among high tempo organizations, vehicles most readily available to maintenance support are those that are in the greatest state of disrepair. Vehicles that are in better condition are preferred by operators for daily operations and are not available. Consequently, the vehicles that are subject to preventative maintenance most often are those near their end-of-life or are in disrepair and therefore gain little through further investments in corrosion prevention initiatives.

Clearly, having corrosion prevention compounds applied to a fleet on an ad hoc basis suffers from the natural bias occurring among operators to retain vehicles in best condition for operational purposes. Corrosion prevention requires a more strategic approach including disciplined maintenance operations in order to provide dividends on a fleet-wide basis.

The growing awareness of the need to conserve material resources is one of the most heartening features of the contemporary industrial scene. Economy of utilisation is the dominant theme of new processes and new industrial undertaking. The farseeing technologist and industrialist no longer think in terms of inexhaustible natural resources. One important proof of this necessary new attitude is the attention now paid to the prevention of corrosion. The increasing cost of steel and other metals has forced industry to look for proved methods and materials for protection against corrosion. The anti‐corrosion armoury now boasts a versatile range of weapons. The pressing need is to get industry to use them. This is where Corrosion Technology comes in. For over three years, with mounting success, we have preached the gospel of corrosion prevention. Now we feel that our efforts should be augmented by a Corrosion Exhibition and Convention. These events will be the principal features of National Anti‐Corrosion Week, which we are sponsoring from October 14–18 next. Details of the exhibition and convention, to be held in Westminster, London, are given on page 147.

This paper deals with the causes and mechanisms of internal corrosion of tanks used for the storage of crude oil and distillates. Services which are considered in this paper include crude oil storage tanks, gasoline blending and/or storage tanks and storage tanks for kerosene and heavier distillates. Fixed‐roof, as well as floating‐roof tanks, are considered. Methods for corrosion prevention and control are discussed.

Many Indonesian operators generally have a tendency to keep their aircraft in service up to or even beyond their economic design goal life (EDGL). The problem that should be solved by the operators is how to operate those ageing aircraft safely and economically. The combination of fatigue and corrosion phenomena needs vigorously corrective action to meet airworthiness requirements, though it increases costs in maintenance. Since corrosion is a never‐ending problem, the aviation community such as designer, manufacturer, operator and the regulatory authority has an obligation to be more concerned and proactive in ensuring continuous airworthiness of the ageing aircraft. Aims to assess issues on corrosion prevention and control activities conducted by Indonesian operators, discusses all the facts and possible corrective actions and provides recommendations to maintain and ensure safe operation of ageing aircraft by controlling and preventing corrosion as well as metal fatigue.
