【摘要】 选用Cr₂O₃、B₂O₃、TiO₂、SiO₂四种常见氧化物活性剂对444超纯铁素体不锈钢进行单组分活性TIG焊,对焊缝进行了电化学腐蚀测试及浸泡腐蚀试验。结果表明,涂覆SiO₂的接头自腐蚀电位高,自腐蚀电流密度低,耐腐蚀性能更好。更多还原

【Abstract】 The single-component active TIG welding of 444 ultra-pure ferritic stainless steel was performed using four common oxides of Cr₂O₃, B₂O₃, TiO₂, and SiO₂. Electrowelding corrosion tests and soaking tests were performed on the welds. The results show that the SiO₂ coated joints have high corrosion potential, low self-corrosion current density, and better corrosion resistance.更多还原
