Abstract

Abstract:

The MoS₂ self-lubrication coating spraying in the surface of 316LN austenitic stainless steel was developed and investigated. The test result shows that the coating had the preferable friction properties at liquid nitrogen temperatures (77K) for high pressure, and the bonding strength test showed that the coating was good adhesion with base materials. In addition, after the thermal shock between 300K and 77K, The coating was free from cracks, flakes and debonding. The average friction coefficient of MoS2 coating under static compression was reported, which indicated that the friction coefficient was less than 0.1, which met the requirements of ITER.

摘要：

研究了在316LN不锈钢板材表面涂覆二硫化钼基自润滑涂层来增加其耐磨性能的方法，此涂层性能优异，与基底之间的结合强度高，室温和77K液氮温度下进行热冲击试验后，涂层表面未出现裂纹，在高载荷(80MPa)、长周期(30000周期)、低温条件下磨损后不失效，满足ITER要求。
