前言本文采用线材火焰喷涂法,对Al—Mg—Re、Zn—Al和Al涂层进行了浸溃腐蚀试验和周浸腐蚀试验。从涂层电位的角度对钝化进行了研究。以考核铬酸锌型封闭剂对涂层抗腐蚀性的影响。以A_3钢为基材的涂层分别放入3%、3.5%、5%的氯化钠溶液中,室温浸泡,测定了这些涂层相对于饱和甘汞电极的电极电位,涂层的常规物理性能,如结合力、硬度等,以便为设计部门选用热喷涂工艺对钢铁构件进行保护提供依据。
Preface In this paper, wire-coating flame spraying method, the Al-Mg-Re, Zn-Al and Al coatings were immersion corrosion test and immersion corrosion test. Passivation is studied from the viewpoint of coating potential. To examine the effect of zinc chromate-type blocking agent on corrosion resistance of coatings. A 3 steel substrate coating were placed in 3%, 3.5%, 5% sodium chloride solution, soaked at room temperature, these coatings were measured relative to the saturated calomel electrode electrode potential, the coating of conventional physics Performance, such as bonding strength, hardness, etc., in order to design department for the use of thermal spraying process to provide protection for steel components provide the basis.
