Abstract A ternary boride cermet coating was prepared on 304 stainless steel by plasma cladding technique. The microstructure and phase composition of the cladding layer were characterized by optical microscope, scanning electron microscope and X-ray diffraction. The hardness distribution of the cladding layer was measured with a micro-hardness tester, and the corrosion resistance of the cladding layer was also studied. The results showed that the boride cladding layer forms a good metallurgical bond with the 304 stainless steel, and no defects such as macro cracks and holes were found at the interface. The average microhardness of the cladding layer was 630.4 HV0.5, which was three times higher than 304 stainless steel (HV0.5≤200), effectively improving the surface hardness of 304 stainless steel. After immersion test in 10%HNO3+3%HF acidic solution for 48 h, the maximum corrosion depth ratio of the bare 304 stainless steel and the cladding layer is 77 and 9 μm respectively, so the corrosion resistance of the cladding layer is better than that of 304 stainless steel.
