液体碳、氮、硼三元共渗(以下简称三元共渗)是近代发展起来的一项新的表面硬化热处理技术,目前还未被广泛应用。三元共渗是利用原料充足的尿素(CO(NH_2)2)、碳酸钠(Na_2 CO_3)、氯化钾(KCI)和硼酐(B_2O_3),按一定重量比配合加热到熔融状态,使盐浴中碳、氮、硼活性原子渗入零件表面,从而改变零件表面化学成
Liquid carbon, nitrogen, boron ternary permeation (hereinafter referred to as ternary permeation) is a newly developed surface hardening heat treatment technology developed in modern times, has not been widely used. Ternary infiltration is the use of sufficient raw materials urea (CO (NH_2) 2), sodium carbonate (Na_2CO_3), potassium chloride (KCI) and boric anhydride (B_2O_3), according to a certain weight ratio with heating to the molten state, Bath carbon, nitrogen, boron active atoms penetrate the surface of the part, thereby changing the chemical composition of the surface
