摘要
针对现有国内的特种黄铜同步器齿环产品在使用中耐磨性差的情况,研究采用了原位复合法特种工艺———利用扩散-界面原位生成来控制材料中耐磨质点的类型、数量、形态和分布,同时进行固溶-时效热处理、添加微量元素及稀土中间合金等工艺使基体得到强韧化,并进行实验材料的性能测定。检测结果表明,经上述工艺处理后的材料能形成优良的硬质相及表层组织和强韧化的基体组织,其耐磨性能大幅度提高。
The special brass synchronism has been proved a poor property of wear-resistance in use. The paper identified that the matrix of the material has been much strenigthened and toughened by both methods of the following： ① The first is by application of the situ-compound process, which could control the hard phases in numbers, shape, distributiom ② The second is by addition of the trace elements （such as boron） or the mediate alloys （such as cerium-copper ） and by solution heat treatment. It expresses that in experiment and application ： there were got excellent hard phases and extra-surface structures within a strengthening and toughening matrix. The synchronism property of wear-resistance has been improved markedly.
