碳钢和铸铁经抗蚀氮化处理后,可以代替渗镍、镀锌、发蓝等处理,也可以代替有色金属来制造某些受蚀的零件,如气焊嘴、氧气瓣等。经抗蚀氮化处理后的零件,非但能够得到很好的抗蚀表面层,还能增加零件的耐疲性。我厂对低碳钢和球墨铸铁会进行了较长时期的抗蚀氮化试验,到目前为止已获得了一定的成绩,并将逐渐投入生产。试验分抗蚀氮化的工艺试验和抗蚀氮化层的抗蚀性能试验两部分进行。一、抗蚀氮化的工艺试验试验用的材料为3号钢和-54球墨铸铁,精车成直径20公厘、长50公厘的试棒若干
Carbon steel and cast iron after nitriding treatment, instead of infiltration nickel, zinc, blue hair treatment, you can also replace the non-ferrous metals to make some of the parts subject to corrosion, such as welding tip, oxygen valve and so on. After the anti-nitrided parts, not only can get a good surface layer of corrosion, but also increase the fatigue resistance of parts. I plant on the low-carbon steel and ductile iron will be a longer period of corrosion nitriding test, so far has obtained some results, and will gradually put into production. Test points nitriding process corrosion resistance and nitriding layer corrosion resistance of two parts of the test. First, the anti-corrosion nitriding process test materials used for the test No. 3 and-54 ductile iron, fine car into a diameter of 20 mm, 50 mm length of the test bar number
