Abstract

Abstract:

Arc sprayed 3Cr13 coating on the surface of 316LN austenitic stainless steel was developed and investigated to increase the hardness and wear resistant of material for ITER poloidal filed (PF) strut dowel. The bonding strength test shows that the coating has good adhesion with base materials. Micro hardness of the coating is 353MPa, increasing by 23.4% compared to the base material. In addition, the result of friction test shows that the coating has the preferable friction properties at liquid nitrogen temperature (77K) in vacuum, which meet the requirements of ITER PF strut dowel.

Key words: ITER, Arc sprayed, 3Cr13wear-resistant coating

摘要：

按照ITER极向场线圈(PF)销轴的设计要求，考虑到工程制造过程中的实际需求，采用对锻造后的销轴进行电弧喷涂铁基3Cr13耐磨涂层以增加其表面硬度和耐磨性能。所制备的涂层性能优异，与基底之间的结合牢固，表面维氏显微硬度HV0.3为353MPa，比基底材料增加了23.4%，摩擦磨损性能测试表明，涂层材料在77K液氮及真空环境下耐磨性能更优，满足ITER PF销轴的要求。
