Rare-earth aluminum alloy to achieve a hundred years of anti-corrosion?? (Reporter Zhang Hong) China's anti-corrosion technology has a major breakthrough, a hundred years of anti-corrosion patented new technologies, new materials --- rare earth aluminum alloy second-generation products by The successful development of China Shenghua Changyuan Anticorrosion (Group) Co., Ltd. made China's anti-corrosion technology and materials more competitive. Among the many problems plaguing the development of the world's petroleum and chemical industries, the corrosion problems caused by sulfur, hydrogen sulfide, and chlorine ions in the marine environment are a worldwide problem. Rare-earth aluminum alloys have unique anti-corrosion properties due to rare earths and pure aluminum. . A large number of test data shows that the annual corrosion rate of this new patented material is zero or almost zero. The second-generation product of rare earth aluminum alloy - micro-arc plasma TC has completely solved the extremely harsh corrosive environment problems of most arbitrary concentrations of strong acids, alkalis, strong oxidants, etc., can withstand thousands of degrees of high temperature, high pressure, and resistance Grinding, for aerospace, aviation and other fields and petrochemical and other high-pressure oil wells, pipelines, equipment, etc., especially excellent cost performance, compared with the previous generation of products have a wider range of application prospects. This patented technology and materials can be applied to key projects and landmark projects in the country's century-long plan. Workers Daily
