實驗結果表明：本文中幾種燒結鋼的磨損機制均是由磨粒磨損、粘著磨損、和疲勞磨損共同作用的，且以磨粒磨損為主；在燒結態下，復合添加合金元素鎳、鉬的燒結鋼的耐磨性能最好，這是因為生成了大量的硬質相貝氏體；而淬火、低溫回火態下，則復合添加鉬、鎢的燒結鋼的耐磨性能最好，這是因為熱處理態下添加鉬、鎢的燒結鋼的硬度最高。The network carbide and acicular martensites that existed in the microstructure of the root grooves of the spline due to improper carburating and quenching process of the shafts, led to the initiation and propagation of the intergranular microcracks and were the main reason that caused the early fracture of the shafts
