摘要: <正> 钽的耐蚀性非常好,而铬常用作合金元素以提高钢或镍基合金的耐腐蚀性能.钽由于在铁中溶解度过低,用一般方法较难形成表面合金。以钽离子直接注入已有报导。考查离子束混合方法是否能应用于钽将是一项有意义的工作。本文作者进行了钽镀层的离子束混合实验,并在盐酸溶液中考察了其耐蚀特性。所用的基材为 GCr15轴承钢。关于铬注入及离子束混合在文献中已有较多报导。作为对照,

Abstract：Mixing of Ta coating with Xe~+ or mixing of Cr coating with Ar~+ ions implantation in GCr15 bearing steel was studied.In the Ta-mix- ing case,about 6×10~(16) ions/cm~2 a dose was enough to make an amor- phous layer,and anodic polarization tests in chloric acid showed that the corrosion current was suppressed by nearly two orders.In the Cr-mixing case,a Cr_2 O_3 phase dominated layer was formed and the Cr/Fe ratio was measured after immersion test in FeCl_3.The Cr concentration decreased abruptly inside as compared with that of out- side of the pit.
