采用等离子喷涂技术在45钢基体表面上制备了4种不同MoS2含量的AT13/MoS2复合涂层,研究MoS2含量对涂层组织和耐蚀性能的影响。结果表明,AT13/MoS2复合涂层的孔隙率随MoS2含量的增加而升高。由于较高孔隙率的原因,AT13/MoS2复合涂层在80℃的10%H2SO4腐蚀介质中耐蚀性能下降。
Four kinds of AT13 / MoS2 composite coatings with different MoS2 content were prepared on the surface of 45 steel substrate by plasma spray technique. The effects of MoS2 content on the microstructure and corrosion resistance of the coating were studied. The results show that the porosity of AT13 / MoS2 composite coating increases with the increase of MoS2 content. Due to the high porosity, the corrosion resistance of AT13 / MoS2 composite coating in 10% H2SO4 corrosive media at 80 ℃ decreased.
