The development prospect of thermal spraying technology

       In my country, thermal spraying technology is an emerging material protection technology. Because of its flexible process, convenient construction, strong adaptability, high production efficiency and various types of coatings, it can be used for parts repair, material surface protection, and To give new properties to the surface of materials, etc., has become very important in material processing and material science.



The data shows that: in 1976, the National Bureau of Standards announced that the national corrosion loss in 1975 was 70 billion US dollars, which was equivalent to 4% of the national economic output value, and the annual wear and tear loss was estimated to be 140 billion US dollars. United Kingdom: 13.65 pounds in 1971 for the British Isles alone. Switzerland: 500 million kroner was lost in 1969 for only 2 million cars. my country: In 1981, the corrosion amounted to 10.015 billion yuan. In 1980, ten large chemical companies



According to industry statistics, the direct economic loss of corrosion is 3.97%. The annual wear and corrosion of the coal department is 1.7 billion yuan (including 800 million yuan for wear and 900 million yuan for corrosion). According to the statistics of the Ministry of Metallurgy in 1989, the losses caused by wear and corrosion can only be recovered by thermal spraying technology, accounting for 6.9% of the saved value.



From the above data, continuing to widely and deeply promote the application of thermal spraying technology has significant potential social benefits and considerable economic benefits, and the promotion and application of this technology is of great significance.
