Abstract

The invention discloses a thermal spraying treatment process. The thermal spraying treatment process comprises the following steps of (1) metal surface pretreatment, (2) coating treatment, (3) thermalspraying treatment and (4) cooling treatment. According to the thermal spraying treatment process, thermal spraying treatment processes are reasonably improved and adjusted, the thermal spraying treatment effect is improved, a thermal spraying coating which is compact in structure, good in mechanical quality and high in abrasion resistance and corrosion resistance is formed on the surface of a metal matrix, the protection effect on metal is improved, the service life of metal is prolonged, and the thermal spraying treatment process has application and popularizing value.

Description

technical field [0001] The invention belongs to the technical field of metal processing, and in particular relates to a thermal spraying process. Background technique [0002] Metal materials are common and essential materials in people's lives, including iron, steel, aluminum and their alloys. Usually, the surface properties of metal materials are relatively active, and corrosion and other adverse phenomena are prone to occur under natural conditions, which in turn affects their quality and life. Therefore, it is necessary to modify the surface. The thermal spraying treatment method is a common metal surface treatment process, which can form a thermal spray coating on the metal surface to enhance the protection of the metal material, thereby improving its service quality and life. However, the existing thermal spraying treatment process is relatively rough, and the combination of process steps is unreasonable, resulting in low bonding strength between the thermal spraying ...
