| 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. | ||
