Effects of Laser Flux on Surface Quality of the Ablated WC-Co Cemented Carbide AITranslate
Abstract AITranslate
The surface of WC-Co cemented carbide was ablated by ultrashort laser pulse with different laser flux,to remove part of alloy surface material and form new surface.The influences of laser flux on surface quality of the ablated alloy were analyzed from the aspects of surface roughness,residual stress and microhardness.The results show that with the increase of laser flux,surface roughness of the ablated cemented carbide gradually increases,compressive residual stress decreases at first and then increases,and the microhardness is basically unchanged.During the laser machining process,there are irregular micropores along laser trace on alloy surface,and the number of micropores increases with the increase of the laser flux.
