Abstract

Ni60-WC-Co double-layer coating was successfully prepared on TC4 alloy substrate using the rapid hot-press sintering method. The WC-Co coating primarily consists of WC and Co phases, with a small amount of W₂C phase. The Ni60 interlayer is mainly composed of four phases: FeNi₃, Cr₇C₃, CrB and Cr₂B. A diffusion layer of approximately 500 μm was formed between the Ni60 interlayer and the TC4 substrate. The Ni60 interlayer significantly improved the interfacial bonding between the WC-Co coating and the TC4 substrate. Dense interfaces were formed between the TC4 substrate, the diffusion layer, the Ni60 interlayer, and the WC-Co coating, with no micro-porosity or cracks observed. Compared to the TC4 substrate, the microhardness and wear resistance of the coating were increased by 3.42 times and 12.12 times, respectively.
