详细说明
Mould of vacuum heat treatment technology
真空热处理技术是近些年发展起来的一种新型的热处理技术,它所具备的特点,正是模具制造中所迫切需要的,比如防止加热氧化和不脱碳、真空脱气或除气,消除氢脆,从而提高材料(零件)的塑性、韧性和疲劳强度。
真空加热缓慢、零件内外温差较小等因素,决定了真空热处理工艺造成的零件变形小等。
按采用的冷却介质不同,真空淬火可分为真空油冷淬火、真空气冷淬火、真空水冷淬火和真空硝盐等温淬火。
According to the different cooling medium, vacuum oil quenching can be divided into cold hardening, vacuum gas cooling hardening, vacuum water quenching and vacuum nitrate isothermal quenching.
