介绍了用于492 QC小型高速柴油机曲轴的几种材料的离子氮化层性能的弯曲试验方法。试验结果表明,从氨化层的塑性看,选用40Cr和35CrMo上述曲轴材料是适宜的。
The bending test method for the performance of the ionic nitride layer of several materials for the 492 QC small high speed diesel engine crankshaft is introduced. The test results show that, from the plasticization of the ammoniated layer, the choice of 40Cr and 35CrMo crankshaft material is suitable.
