Metallic finishing of materials, unlike non‐metallic finishing, comprises various popular surface modification processes, e.g. electroplating, conversion coating, anodizing, metal…

Inhibition by phosphonic acids ‐ an overview

G. Gunasekaran, R. Natarajan, V.S. Muralidharan, N. Palaniswamy, B.V. Appa Rao

Phosphonic acids are good complexing agents. However, they are not good as inhibitors except for a very few. Synergistic inhibition is offered in the presence of metal cations…

Corrosion behaviour of silver brazing alloys in different environments

S.C. Dev, Inder Singh, D.K. Basu, A.K. Bhattamishra, C.S. Sivaramakrishnan

Corrosion data of the widely used silver brazing alloys (BAg‐1 and BAg‐3) of the American Welding Society’s (AWS) specification are scant in literature. Deals with the study of…
