摘要
以Fe-Ni-Mo系合金粉作为基础，研究了Cu，C含量对内齿圈力学性能和烧结膨胀率等的影响。并研制出密度为6．95g／cm^3，烧结膨胀率为0．15％，硬度为HRC33-38，齿根抗弯强度达到570MPa的QDJ2829起动机内齿圈，其技术指标达到了产品要求指标．
A Fe-Ni-Mo alloy prepared by power metallurgy was investigated including the influences of different content of Cu, C on the mechanical properties and sintering expansion rate. The QDJ2829 starter ring gear with density of 6.95g/cm^3 and sintering expansion rate of 0.15% was made by Fe-Ni-Mo alloy. Its technical indices such as hardness of HRC33-38 and the tooth root bending strength of 570MPa have reached product requirements.
