| 摘 要： | 为了降低渗硼层的脆性，提高其耐磨性，对20G钢渗硼层进行了氩弧重熔处理，研究了渗硼层重熔前后的形貌、相结构、显微硬度及耐磨性。结果表明：渗硼层由FeB和Fe2B两相组成，经氩弧重熔处理后FeB相消除，氩弧重熔渗硼层由Fe23（C，B）6和Fe2B相组成，包括氩弧重熔区和过渡区；氩弧重熔处理使渗硼层表层微观硬度降低，且使...

| Abstract: | The boronizing coating of 20G steel was treated by argon arc remelting so as to decrease the brittleness and increase wear resistance. The morphology, phase structure, microhardness and wear resistance of the boronizing coating before and after argon arc remelting were analyzed. Results indicate that the boronizing coating is composed of FeB and Fe2 B. After argon arc remelting, FeB phase disappeared, and argon arc remelted zone and transition zone were formed, while new phase Fe23 (C,B) 6 was generated alo... |
