碳氮硼三元共渗是一种适用于各种钢材和球墨铸铁的化学热处理新工艺,简称“三元共渗”。 目前我国已经初步试验成功并用于生产的三元共渗,有液体三元共渗和气体三元共渗两种工艺。前者是玉门石油管理局机械厂热处理工人、干部和技术人员在综合分析渗碳、渗氮、渗硼的优缺点的基础上,破除迷信,解放思想,于1973年试验成功的;后者是由兰州石油机械研究所试验成功的。 Carbonitride boron ternary permeation is a new chemical heat treatment process suitable for a variety of steel and ductile iron, referred to as “ternary infiltration.” At present, China has been initially tested successfully and used in the production of ternary percolation, liquid ternary and gas ternary infiltration two processes. The former is the Yumen Petroleum Administration Machinery Plant heat treatment workers, cadres and technical personnel in a comprehensive analysis of carburizing, nitriding, boron infiltration on the basis of the advantages and disadvantages, to get rid of superstition, emancipate the mind, a successful trial in 1973; the latter is Lanzhou Petroleum Machinery Institute successfully tested.
