Due to the importance of aluminum alloys in different industrialapplications because of their light weight and maintaining their highresistance to corrosion, attention is focused on using different techniques toimprove the characteristics of these alloys. Alloys of Al-4.5%Cu are used assubstrate for coating with compound material of abase of aluminumenforced with ceramic substance (SiC) using plasma spray technique.Spraying operation has been done using (180 mm) as distance spray andconstant spraying current (550A).Heat treatments have been done usingvacuum furnace with discharge pressure 6*10-4 torr and temperature 550Cofor two hours. The testing techniques which had been used are hardnessbefore and after heat treatment, wear test after heat treatments by differentslipping distances and influence wear test on micro structure to study theeffect of addition SiC percentage and slipping distance on wear rate. Fromthe result, is seen that wear rate is decreased with increase in slippingdistance and addition percentage.
