Publication Date : 25/04/2019
In this paper we are studying a tribo layer in dry Sliding of Al Si alloy. Al-Si alloys are widely used in cast form in critical components in automobile application like pistons, valve lifters, cylinder liners, engine blocks, etc due to their high strength to weight ratio, excellent casting characteristics, good mechanical property including wear resistance low coefficient of thermal expansion, high thermal conductivity and high corrosion resistance. are generally utilized in cast structure in basic segments in car application like cylinders, valve lifters, barrel liners, motor squares, and so on because of their high solidarity to weight proportion, fantastic throwing qualities, great mechanical property including wear opposition low coefficient of warm development, high warm conductivity and high erosion obstruction. The formation of tribo layer has commonly been observed in dry sliding of Al Si alloys or generally in most sliding surface, although they may not have been termed as tribo- layer. In their investigation of dreary, rash and nonstop sliding contact of different metallic sets, described the microstructure of surface and subsurface area dependent on the minuscule and spectroscopic proof. In which three unmistakable zones were distinguished and the highest layer was named as tribo-layer by a different specialist.
