| 摘 要： | The effect of the laser processing parameters on the composition uniformity and shapecoefficient of fusion zone with laser surface alloyed Cr plated on medium carbon low alloysteel has been studied.It was found that the composition uniformity depends on the shapecoefficient of fusion zone,and the later is a function of both power density and interactiontime.If the power density is fixed to a certain value,the shape coefficient is directly,propor-tional to the interaction time.A completely,uniform molten pool can be obtained,when theshape coefficient is between 1.6 and 3.0.
