Reduction of Wear Effect for Copper- Silicon Alloy by Laser Treatment


Copper- silicon alloy was prepared by CNC machining into disc shapes with diameter 18mm and thickness of 3mm using CNC machine to obtain more accuracy dimensions .Grinding and polishing process were carried out for all samples, and conducted to Nd-YAG laser treatment. Laser conditions involved laser fluency of 500mJ, wavelength of 1064nm, and different number of laser pulses (20, 40 and 60 pulses). The samples were subjected to wear system measurements before and after laser treatment to calculate the wear rate with different situations. The results revealed that the wear rate was reduced by 15% after laser treatment.
