Abstract
Due to the importance of aluminum alloys in different industrial
applications because of their light weight and maintaining their high
resistance to corrosion, attention is focused on using different techniques to
improve the characteristics of these alloys. Alloys of Al-4.5%Cu are used as
substrate for coating with compound material of abase of aluminum
enforced with ceramic substance (SiC) using plasma spray technique.
Spraying operation has been done using (180 mm) as distance spray and
constant spraying current (550A).Heat treatments have been done using
vacuum furnace with discharge pressure 6*10-4 torr and temperature 550Co
for two hours. The testing techniques which had been used are hardness
before and after heat treatment, wear test after heat treatments by different
slipping distances and influence wear test on micro structure to study the
effect of addition SiC percentage and slipping distance on wear rate. From
the result, is seen that wear rate is decreased with increase in slipping
distance and addition percentage.
