英国Consarc工程公司最近安装了一台最大处理量达5吨的等离子氮化炉,用来氮化处理齿轮,以提高齿轮的承载能力、耐磨性能、疲劳性能和摩擦性能,但其尺寸不产生明显变化。等离子氮化是在真空下进行的。最初阶段,由于溅射放电作用,等离子放电对部件进行清洗。当部件达到处理温度时,即可连续进行氮化处理直到处理中止,尔后部件在真空下冷却。 British Consarc Engineering recently installed a plasma nitriding furnace capable of handling up to 5 tons of nitrocarburizing gear to improve gear carrying capacity, wear resistance, fatigue and friction but not in size obvious change. Plasma nitriding is carried out under vacuum. During the initial stages, the parts were cleaned by plasma discharge due to the sputtering discharge. When the part reaches the processing temperature, the nitriding can be continued until the treatment is stopped, and the part is then cooled under vacuum.
