Tribological Properties of Coated Tool Materials and Wood-Based Materials
摘要
Abstract
[Objective]The tribological properties of coating materials and wood-based composites were analyzed, which can provide practical guidance for the research on wear and cutting performance of coated carbide cutting tools.[Method]The effects of the coated cutting tool and wood-based materials on the tribological properties were investigated by examining how TiN and MoS2 coated cemented carbide behavior in sliding when in contact with wood-based composite materials,respectively,and by comparing their behaviors with those of uncoated cemented carbide.[Result]The results showed that the friction coefficients of MoS2 coated cemented carbide with MDF,PB and WFPEC,respectively,were significantly lower than those of uncoated cemented carbide and TiN hard-coated cemented carbide,and that of the TiN coated cemented carbide was the lowest. The friction coefficients of PB with uncoated cemented carbide,TiN and MoS2 coated,respectively,were significantly lower than those of MDF and WFPEC,and that of WFPEC was the lowest. In the friction test of uncoated cemented carbide,TiN and MoS2 coated cemented carbide with MDF and PB,respectively,the friction coefficients increased with the increase of load. However,in the friction test of WFPEC,the friction coefficients exhibited independent with load. The change rate of the surface roughness for uncoated cemented carbides was the highest before and after the MDF friction test,followed by the MoS2 coated cemented carbide,and the smallest change rate of the surface roughness was found in the TiN coated cemented carbide.[Conclusion]Both TiN and MoS2 coating materials could effectively reduce the friction coefficients of tool materials and wood-based composite materials,and the friction coefficient of MoS2 coated cemented carbide was lower than that of TiN coated cemented carbide. The wear resistance property of TiN coated cemented carbide was becter than that of MoS2 coated cemented carbide.关键词
