摘　　要：研究了几种钝化剂对金属粉末表面的稳定化处理工艺，分析了其钝化机理。经钝化处理后的粉末，其抗氧化性显著提高，而其他物理性能及化学组成基本保持不变。稳定化处理对金属粉末的生产具有很重要的意义。Surface stabilization of metal powders were processed with some oxida-tion - retarder. oxidatiOn retardation mechanism was discussed in this paper. Thestabilized powders have obvious better oxidation resistance than unstabilized Pow-ders. And the other physical and chemical properties remain constant. Therefore,surface stabi1ization process is of great significance to the industrial production of metal powders.
