Abstract
A TiC particle dispersively reinforced composite coating on alloy Ti6Al4V h as successfully been synthesized by YAG pulse laser induced melting and rea ction of a powder mixture, which consisted of pure Ti and Cr2C3 and promptl y pre-placed on the alloy surface. Tt follows that with help of optimal pro cess parameters and a suitable composition of the powder mixture, a composi te coating can be obtained with the features of good metallurgical bonding with the alloy, and of graded distribution of the fine dispersive particles of TiC in the coating matrix. The TiC particle showed good wettability and compatibility with the matrix of the coating with a sharp and clear interf ace between them. The microstructure of the composite coating varied with t he composition of the powder mixtures and also the laser processing paramet ers. Furthermore, such a composite material coating offered the alloy Ti6Al 4V high hardness and excellent wear resistance. (C) 2001 Elsevier Science B .V. All rights reserved.
