利权输送机溜槽等离子体碳础共渗研究．其三洋等（46－47）选用合适或渗剂及工艺参数，利用长压等离子体分热源对矿刮板运输机溜槽实现了碳硼共渗及表面淬火。表层硬度达HV50595（HRC56）以上，硬度分布合理。
Study on Plasma Carbon Infiltration in Profit Conveyor Chute. Sanyo, etc. (46-47) choose appropriate or penetration agent and process parameters, the use of long-pressure plasma sub-heat source on the scraper conveyor chute to achieve carbon boron and surface hardening. Surface hardness of HV50595 (HRC56) above, the hardness distribution is reasonable.
