前言自从Sulf·B·T法在法国问世以来。人们在渗硫工艺和渗硫设备等方面,做了大量的试验研究工作。近几年来,国内在采用井式炉气体渗硫和辉光离子渗硫时,一般都是进行二元、三元和多元共渗,很少采用单纯渗硫。渗硫虽然有良好效果,但因有工艺比较复杂、质量尚不够稳定,设备投资高等 Foreword Since the advent of Sulf BP Law in France. People in the sulfur infiltration process and sulfur infiltration equipment, has done a lot of experimental research. In recent years, the domestic use of pit furnace gas sulfur and glow ion infiltration sulfur, are generally carried out binary, ternary and multiple infiltration, infiltration of infiltration is rarely used alone. Although sulfur infiltration has good results, but because of the more complex process, the quality is not yet stable enough, high equipment investment
