【摘要】 本文采用(PVD)非平衡磁控溅射技术,在304不锈钢表面沉积CrTiAlN硬质涂层,测定和研究涂层表面性能和耐腐蚀性能,探索提高奥氏体不锈钢表面性能和耐腐蚀性能的可能性。基于奥氏体不锈钢在含氯离子酸和非氧化性酸中缺乏足够抵抗力的特点,腐蚀介质选用了0.5Mol/L的NaCl水溶液。结果表明CrTiAlN涂层试样表现了优异的表面性能和耐腐蚀性能,特别是对于提高304不锈钢耐点蚀的能力有很大作用。更多还原

【Abstract】 In this paper,CrTiAlN coating has been deposited on surface of 304 stainless steel using an unbalanced magnetron sputtering technology.Coated surface properties and corrosion resistance are characterized with a view to exploring the possibility of improvement in performance.Considering the austenitic stainless steel in the chlorine ion and non-oxidizing acid in the absence of sufficient acid resistance characteristics,0.5Mol / L of NaCl aqueous solution was selected as a corrosion medium.The results shows that the coated CrTiAlN sample exhibit excellent surface properties and corrosion resistance,especially for that improved pitting resistance of 304 stainless steel plays a significant role in the ability.更多还原
