在石油化工生产中,有盐酸与有机溶剂或者稀硫酸与有机物同时存在的条件下,钛材具有优良的耐腐蚀性。如岳阳化工总厂将钛材应用于含7—8%的稀硫酸的羟胺硫酸盐介质中的设备上使用,抗腐蚀效果显著,腐蚀率为0.02毫米/年。为了进一步提高钛材在其他浓度中酸的抗腐蚀性,对钛合金和钛材采用辉光离子氮化处理,使其表面形成一层氮化钛保护
In petrochemical production, hydrochloric acid and organic solvents or dilute sulfuric acid and organic matter exist under the conditions of titanium has excellent corrosion resistance. Such as Yueyang Chemical Plant will be used in titanium containing 7-8% of hydroxylamine sulfate medium containing dilute sulfuric acid medium equipment, anti-corrosion effect is significant, the corrosion rate of 0.02 mm / year. In order to further improve the titanium in other concentrations of acid corrosion resistance, the titanium alloy and titanium using glow ion nitriding, the surface to form a layer of titanium nitride protection
