A three-dimensional model was proposed to simulate high power laser clad TiC/NiCrBSiC composite coatings on Ti6Al4V alloys. Molten pool depth and dilution rate were obtained and compared with the experimental results. The calculated molten pool depth in the sample is about 0.76 mm and dilution rate is 21 %. The experimental data molten pool depth and dilution rate were 0.81 mm and 26%, respectively. There is a good agreement between the numerical and experimental results. A good quality laser clad TiC/NiCrBSiC coating with low dilution rate and excellent metallurgical bond can be prepared under the optimal parameters.
