利用常压等离子体扫描金属表面,实现了快速扫描多元共渗。用此技术对硼铸铁气缸套进行了B-Si-Re多元共渗。通过电子探针、金相显微镜对多元共渗层的成分、组织进行了观察,利用显微硬度计测定了共渗层的硬度分布。95型硼铸铁气缸套分别进行等离子多元共渗与激光处理,对比磨损试验结果表明:等离子多元共渗气缸套的耐磨性及配副性能优于激光处理气缸套;缸套耐磨性提高7.7%,活塞环耐磨性提高4.1%,达优等产品标准。且设备投资少,生产效率高,生产过程稳定。
Using atmospheric plasma scanning metal surface, to achieve a rapid scanning multivariate permeation. Boron cast iron cylinder liner with this technology B-Si-Re multiple infiltration. The composition and microstructure of the multiple co-permeation layer were observed by electron probe and metallographic microscope. The hardness distribution of the co-permeation layer was measured by micro-hardness tester. 95 type boron cast iron cylinder liner were plasma multivitamin infiltration and laser processing, comparative wear test results show that: plasma multivibrator infiltration cylinder liner wear and auxiliary performance is better than the laser processing cylinder liner; liner wear resistance increased by 7 .7%, the piston ring wear resistance increased by 4.1%, up to excellent product standards. And equipment investment, high production efficiency, the production process is stable.
