摘要
采用有限元法计算了高频感应熔覆NiCrBSi涂层的基体和界面在不同工艺参数下的温度分布,并采用高频感应加热技术在抽油杆钢35CrMo表面制备NiCrBSi涂层。模拟结果表明,在感应加热频率105 Hz,感应加热电流1400 A,感应加热时间14 s时,涂层达到了NiCrBSi的熔点1100℃,此时抽油杆与镍基涂层形成了冶金结合。通过对熔覆层组织形貌观察及相结构分析,验证了模拟结果的准确性和可靠性,为高频感应熔覆工艺参数的优化提供了理论依据。
The temperature distribution in the substrate and coatings under different processing parameters was established using finite element method, NiCrBSi coating was manufactured on 35CrMo sucker rod steel using high fi＇equency induction heating technology. The results show that the melting point of NiCrBSi alloy arrives 1100 ℃ when the frequency is 105 Hz, the current is 1400 A, and the heating time is 14 s. At this time, the metallurgical bonding is formed between the NiCrBSi coating and substrate. The simulation results are in accordance with the experimental ones, through observing the cladding coating structure and analyzing the phase, which can offer reliable optimization of the high frequency induction parameters on the sucker rod.
