合金粉末喷涂(焊)、电刷镀是金属表面处理新技术。在“六五”期间,冶金系统热喷涂(焊)、电刷镀技术的推广工作取得很大成绩,获直接经济效益五千万元、社会效益两亿元以上。这项新技术具有焊、镀层厚度均匀、结构致密、表面光滑、与基体结合强度较高等优点,使涂(焊)、镀工作表面获得高的耐蚀性,以及抗磨、耐热、抗氧化的保护层,提高了零部件的使用寿命,已广泛应用于冶金设备的备件维修及部分新部件的制造。据此,“七五”期间,国家经委和冶金部仍将热喷涂(焊)、电刷镀技术列为重点推
Alloy powder coating (welding), brush plating is a new technology of metal surface treatment. During the period of the Sixth Five-Year Plan, great efforts have been made in the popularization of thermal spraying (welding) and brush plating of the metallurgical system, with a direct economic benefit of 50 million yuan and a social benefit of over 200 million yuan. The new technology has the advantages of welding, coating thickness uniformity, compact structure, smooth surface, high bond strength with the substrate, etc., to achieve high corrosion resistance of coated (welded) and plated work surfaces, as well as wear resistance, heat resistance and oxidation resistance Of the protective layer to improve the service life of parts and components, has been widely used in spare parts maintenance of metallurgical equipment and the manufacture of some new components. Accordingly, during the “Seventh Five-Year Plan” period, the State Economic Commission and the Ministry of Metallurgical Affairs still listed thermal spraying (welding) and brush plating as the key push
