    • Abstract
  • The influence of surface roughness on laser absorptivity was studied to better control the temperature of workpiece during laser heat treatment process and supply more precise calculate model of laser absorptivity for mathematical simulation.The surface outline of material was equivalent treated,then mathematical model was set up.The laser aborptivity was measured by lumped parameter method,which was agreed with the value of laser absorptivity calculated by theoretical formula.The results indicated that the mathematical model could exactly describe the influence of surface roughness on laser absorptivity.
