The main purpose of the research paper is to study the effect of refinement of primary silicon on sliding wear behavior of commercially available LM-28 alloy and correlate these with the micro-structural and mechanical properties. It is well known that the refinement of primary silicon increases the toughness, ultimate tensile stress (UTS) and wear resistance of the Al-Si alloys at ambient temperature. But exact addition level is not clearly mentioned in the paper; hence, the present paper throws light on the addition level for refinement of primary silicon present in LM-28 alloy.

In the present paper, commercially available LM-28 alloy was prepared in the laboratory before and after the addition of Cu-P master alloy. Further wear studies will be carried out at room temperature. Wear properties are correlated with microstructure and mechanical properties.

Improvements in mechanical properties were observed after refinement of the primary silicon present in LM-28 alloy.

Further studies are required regarding in-depth investigation of refinement of primary silicon and its effects on the life of the components prepared by this alloy.

The data obtained from the research paper help the manufacturers of automotive, aerospace and marine components, such as pistons, cylinder heads and blocks, etc.

The present research work will be an essential information required for the students of undergraduate, postgraduate and research scholars to carry out research at an R&D centre.

Experiments are conducted at an R&D centre and analyses were carried out for structural changes, mechanical properties and wear properties. Further, the results are compared with other researcher’s data.
