30CrMnSiA钢激光表面淬火的显微组织及耐磨性
Microstructure and Wear Resistance of Laser Hardening Layer on 30CrMnSiA Steel
【摘要】 采用功率为 2kW ,扫描速度为 10 0mm/min的工艺参数对钻杆接头材料 30CrMnSiA钢进行了表面相变硬化处理 ,研究了相变层的组织和耐磨性。实验结果表明 ,30CrMnSiA钢表面相变硬化层分为完全淬硬层、过度层和受热影响的基体组织 ,硬化层的显微组织明显细化 ,其表面层的耐磨性明显高于未经激光处理的 30CrMnSiA钢。
【Abstract】 Surface hardening of drill-stem joint material 30CrMnSiA by using 2kW power and 100mm/min scanning velocity has been performed, The microstructure and wear resistance of the transformation layer have been studied ,The experimental results show that the surface hardened layer consists of the hardened region and the interim region and the temper microstructure,The microstructure of hardened layer was very tiny,Its wear resistance higher than the 30CrMnSiA steel in the normal state
