Paper Abstract

Laser phase transformation hardening is an important field of laser application industry, and the choice of its technological parameters influences the depth and width of hardening layer directly. In this paper, from the basic equation of heat conduction, the relationship between parameters such as laser power of Gauss distribution, out of focus and scanning velocity and the depth, width of hardening layer is obtained, and a series of computer soft about choice of technological parameters is compiled. Experiments show that the relativity error of width of hardening layer between theoretical calculation and experimental results is 5.7 percent and the error of depth is 18.7 percent.
