In this paper; boronitriding; a method of chemical heat treatment; was used to change the chemical composition of the surface layer of carbon steel and cast iron; improve the structure of the surface layer and increase the electrode potential; so as to obtain the acid-resistant corrosion layer.Through a series of heat treatment process; acid corrosion resistance test and metallographic analysis; the best boronitriding agent formulation and treatment process were determined.When the flake graphite size of gray cast iron is less than grade 4; the acid corrosion resistance of gray cast iron can be significantly improved by boronitriding.Ordinary carbon steel after treatment; at room temperature; can withstand different concentrations of hydrochloric acid; sulfuric acid corrosion.Therefore; under appropriate conditions; it can be used to replace some stainless steel and save the rare nickel-chromium alloy.

本文通过化学热处理的方法——硼氮共渗,来改变碳钢与铸铁表层的化学成份,改善表层的组织结构和提高电极电位,从而获得耐酸腐蚀层。通过一系列热处理工艺,耐酸腐蚀试验和金相分析,确定了最佳的硼氮共渗剂配方及处理工艺。灰口铸铁的片状石墨尺寸小于四级时,硼氮共渗可显著提高其耐酸腐蚀性能;普通碳钢处理后,在常温下,能承受不同浓度的盐酸、硫酸的腐蚀。因此,在适当条件下,可用它来代替部分不锈钢,节约稀贵的镍铬合金.
