摘　　要：以机械液压杆用40Cr合金钢为研究对象,在其表面喷涂不同成分的陶瓷涂层,研究涂层的孔隙率、微观形貌和电化学性能。结果表明,氧化铝+20%氧化钛复合涂层的自腐蚀电位和点蚀电位明显高于其它涂层,耐腐蚀性能最好。The porosity, microstmcture and electrochemical performance of ceramic coating on 40Cr alloy steel, which was used as the mechanical hydraulic rod, were studied. The results show that the best corrosion resistance of the ceramic coating is alumina and 20% titanium oxide composite coating, which shows higher corrosion potential and pitting potential.
