| 摘 要： | 以齿轮为研究对象，用辊子模拟方法，对４５＾＃钢制试件进行激光表面铬合金化，然后与４０Ｃｒ钢调质试件和４０Ｃｒ钢高频淬火试进行接触强度对比试验。结果表明：４５＾＃钢试件经铬合金化后，其接触疲劳寿命比４０Ｃｒ钢调质试提高１１．７７倍，而与４０Ｃｒ钢高频淬火试的接触疲劳寿命相当。用扫描电研究分析其显微结构及提高接触强度的机理。

| Abstract: | Based on contrast experiment simulated sugarcane crusher gear drives,investigates effect of the Laser surface Chromium Alloying treatment on the contact fatiguelif e on the slipping contact surface. The experimental results are analysed and conclusion isas follows f the contact fatigue life of the roller made from 45 carbon steel and treated withLaser sun'ace Chromium Alloying was increased remarkablely than that of the roller madefrom 40 Cr steel with hardening and tempering, but thair contact fatigue life and that ofthe roller made from 40Cr steel with high--frequency hardening are well-matched. Themechanism why the contact thtigue life was raised is analysed. |
