Abstract: In order to improve the surface performance of A3 steel,we utilize a high power CO2 laser beam to treat the B4C-TiN-Co clad surface.It is obvious that the laser beam scanning speed is an important factor effecting on the microstructure,hardness and the resistance to abrasion of the alloy surface.This paper introduces the experimental research procedure,and the experimental results.These are useful to select the beam scanning speed and other technical parameters.
