Abstract

Abstract: Tribological performance as wear properties, wear scar morphology, wear degree and S content change of sulfurized layer on the surface of the W6Mo5Cr4V2 steel prepared by ion sulfurization and liquid sulfurization were analyzed by means of friction and wear test, wear surface morphology measurement and EDS analysis, and the stability and reliability of ion sulfurized part and liquid sulfurized part were comprehensively compared by appearance, size detection and microscopic wear morphology through operation test. The results indicate the friction coefficient, service life, maximum depth and area of wear scar and sulfur content of ion sulfurized layer are all equal to or better than those of liquid sulfurized layer. The operation test results show that both ion sulfuration and liquid sulfuration can meet the performance needs of the products.

Key words: ion sulfurization, tribological performance, liquid sulfurization
