AGEING EFFECT ON SLIDING WEAR BEHAVIOR OF AL-CU ALLOY AND COMPOSITE - A COMPARATIVE STUDY
Keywords:
Stir Casting, Dispersion, Sliding Wear, AgeingAbstract
Work has been carried out to study the effect of alloying element dispersion in the base metal by using composite fabrication technique. Al- 5% Cu particulate composite prepared by stir cast method by dispersing copper powder (filings) in molten aluminium. Sliding wear studies are carried out at homogenized and aged conditions. Results are compared with the alloy having same composition. Composite show better wear resistance compared to the alloy in homogenized condition. Typical behaviour of higher wear is observed with the composite in T6 (aged) condition. This may be attributed to the formation of alloy during heat treatment. Microscopy corroborates the above results
