Review on cast iron wear behavior at various temperatures

Abstract

Cast iron is the highly useful material due to its excellent mechanical and wear properties.Temperature is a variable which depends on friction between the material components. Grey cast iron, ductile cast iron, compact graphite iron are the important materials in various automotive applications. Mainly CGI is useful material in automobile sectors. In automobiles it is used in making of engine blocks, brake drums and exhaust manifolds etc. Brake drums are experienced with high temperatures. In the present review studies grey cast iron, ductile iron and compact graphite iron is considered for wear studies. In comparison compact graphite iron has the mechanical and thermal properties in between grey and ductile iron. The cast iron specimens are undergone for wear test by pin on disc test rig. Wear rate and frictional behavior are affected by microstructure and distribution of carbon particles and pearlite and ferrite phase. Wear tests are conducted at various temperatures. Worn surfaces are analysed by scanning electron microscopy and EDAX.
