Technology Research and Performance Verification of Laser Cladding WC/Co Coating on High Speed Steel Tool
In view of the shortage of hardness and red hardness of high speed steel tool in high-speed cutting and high-hard material cutting, WC/Co coatings is fabricated on the surface of high speed steel turning tool by using laser cladding technology to improve tool performance. The influence of different pre-processing morphology on the cladding layer is studied, the method to solve the problem of the inconsistency of the turning edge angle in the process of cladding is put forward, and the actual cutting performance of the coated tool is verified. The results show that the pre-laid groove cladding is a reasonable pre-processing morphology, the micro-hardness of the cladding layer is 57% higher than of the turning tool substrate, at 600 ℃ the red hardness of the cladding layer is 0.25 times higher than that of the turning tool substrate, and at 1 000 ℃ the red hardness reaches more than 50HRC. the design of special cladding flip fixture can effectively adjust the angle of tool edge angle. The cladding turning tool shows excellent practical performance in high-hard material cutting and high-speed cutting.
