【Abstract】 This paper studied the impact of trace boron on the microstructure and performance of C100 drive gear and the influence of both surface quenching and plasma nitriding on the performance were investigated. The results showed that the addition of trace boron can improve the hardenability of gear materials and the grain refinement of hardening layer. The quenching layer of the sample of boron containing about 0. 003% was the thickest and the grains of this sample were finer. The depth of the hardened layer was close to that of the 16- hour- nitrided layer,but the hardness of high frequency quenching was higher.更多还原
