金属表面渗硫技术是国际上70年代研究成功并获得深入发展的一项固体润滑新技术,在美、日、法等国已广泛应用于汽车零件和机械基础件。我国在80年代研制成功了“低温气体电离渗硫技术”,近年来在国内多处应用。该工艺简单实用。方法是将零件放在充满渗硫气体的真空反应室内,在高压直流电场作用下产生辉光放电效应,工件加热主要靠离子轰击的能量转换。高能 Metal surface sulphurization technology is a solid lubricating new technology successfully researched and developed in the 1970s. It has been widely used in automobile parts and mechanical foundation parts in the United States, Japan and France. China successfully developed in the 80’s “low-temperature gas ionization sulfurization technology”, in many places in the country in recent years. The process is simple and practical. The method is to place the part in a vacuum reaction chamber filled with sulfur infiltration gas and generate glow discharge effect under the action of high voltage DC electric field. The heating of the workpiece mainly depends on the ion bombardment energy conversion. High energy
