Microstructure and Properties of Ti2SC-Ti2Ni Composite Structural Phase Self-Lubricating Laser Cladding Layer on TC4 Surface
To improve the tribological properties of TC4 surfaces, a TC4+Ni60+Ni-MoS2 multi-component composite self-lubricating wear-resistant coating was prepared on the TC4 surface by the TruDisk4002 coaxial powder feeding fiber laser. The microstructure and the tribological performance of this coating were also analyzed. The results show that there are no cracks but a few pores within the coating. The main precipitation phases of the coating are TiC, Ti2Ni, Ti2SC, and α-Ti, and they are uniformly and compactly distributed within the coating. Ti2SC and Ti2Ni form the Ti2SC-Ti2Ni mosaic structure composite phase, and the misfit between (01
