“…They also exhibit strong resistance to crack extension, good low-temperature toughness, and corrosion resistance. As a result, titanium alloys find extensive applications in fields such as aerospace, national defense, and automobile manufacturing [1][2][3][4] . However, due to its high friction factor, wear resistance, and other shortcomings, the safety of actual titanium alloy usage and the stability of structures are reduced.…”

Titanium alloy, with its excellent performance, has been widely used across various industries. However, its high friction factor and poor wear resistance limit further engineering applications. Laser cladding technology, known for its efficiency, rapidity, controllable heat input, and strong metallurgical bonding with the base material, has emerged as an effective method for surface modification of titanium alloys. The TiB-reinforced coatings were prepared by mixing pure Ti powder with h-BN powder on the Ti3Al2V surface of the substrate using laser cladding technology. The effects of laser scanning speeds (1.5mm/s, 3mm/s, 4.5mm/s, and 6mm/s) on the microstructure and microhardness of the fused cladding layer were experimentally investigated. The results indicate that the fused cladding layer exhibited a needle and rod-like structure, identified as the reinforced phase TiB. As the laser scanning speed increased, the size of the reinforced phase gradually decreased, while the number of particles increased, resulting in an uneven distribution. Surprisingly, the hardness of the fused cladding layer did not decrease with the increase in laser scanning speed; instead, it reached its highest value at a speed of 6mm/s. Furthermore, the hardness of the fused cladding layer surpassed that of the substrate. Overall, the optimal hardness was achieved at a laser scanning speed of 6mm/s.
