Prediction of Processing Parameters of Laser Clad TiC/NiCrBSiC Coatings on Ti6Al4V by Finite Element Analysis

Abstract:

This work deals with the processing parameter prediction of laser clad TiC/NiCrBSiC coatings on Ti6Al4V alloys by Finite Element Method. Temperature distribution and dilution rate were obtained. The temperature distributions were sparse and enlarged when laser power increased. With increasing of scanning velocity, the temperature distributions were compressed and lengthened at the front and at the end of the laser beam, respectively. Under laser power P=2.5 kW, scanning velocity V=5 mm/s, the calculated and experimental dilution rates are 6.25% and 8.3%, respectively. There is a good agreement between the results.
