الملخص EN

Improvement of Wear adhesive properties using laser peening treatment at varied number of pulse of Austenitic stainless 316L is studied.

According to typical ASTM G99-05 number of wear inspection test are prepared in dimensions 20x10 mm then compiled into four groups.

The surface test of three groups is exposed to a number of laser pulse 1, 2, 4 pulses respectively by laser peening without coating.

Microstructure, residual stress, hardness, is tested.

Wear test using pin on disc method are used on all groups of specimens at two parameters, diverse times 10 ,20,30 min with constant load 1kg , and divers load 1,1.5, 2 kg with constant time 10 min.

from results it was concluded that decrease in hardness and rises in ductility shared to increases in wear properties for the original metal and leaser peening participated to rise in the wear resistance due to increase in hardness , compression residual stress and the heterogeneity of the evidence in the microstructure ,four pulse laser peening give the lowest wear rate comparing with one pulse which witness decreases in wear rate.
