In order to improve the penetration performance of TC4, the direct laser deposition technology was used to prepare TC4 composite material.TA15+30% TiC powder, TA15+20%Cr3C2 powder and TA15+15%B4C powder were used as deposited materials for TC4 matrix.The micromorphology, change of hardness of the deposited Wireless Headphones coating and mechanical properties of the three composites were studied.The experimental results demonstrate that the TC4 matrix with the three kinds of materials can form a complete metallurgical bonding, and the strength of TC4-(TA15+TiC), TC4-(TA15+Cr3C2) and TC4-(TA15+B4C) are higher than that of Ear Plugs TC4 matrix materials, while the plasticity is slightly worse.
