【Abstract】 B-penetrated layer of steel surface have the excellect feature of high hardness,resist-wear and resist-corrode ,the technology of B-penetrate is the fine measure to enhance the resist-wear feature of mechanical part, this paper analyzed the technology and performance, especially put it into use in the plant, the experimental results reveal: the wear mass loss of 45-steely surface B-penetrate follow general wear rules of mechanical part with the varying curve of machining number, in the same working condition, the working life of 45 steely B-penetrate boring-ringer is 5.37 times as long as boring-ringer of T9-quenching,greatly prolonging the working life of boring-ringer part.3figs.,1tab.,5refs.更多还原
