Overview of The Thermal Spraying Technology

Thermal spraying is one of the techniques for preparing coatings, which has become one of the new technologies of surface protection and reinforcement. The most prominent characteristics of thermal spraying technology are the diversity of thermal spraying methods, the generalization of the coating and the economical efficiency of the application. Thermal spraying technology is playing a unique role in the fields from the protection of large steel components to special functional coatings in the high-tech field, from the manufacture of modern aircraft to the urban facilities. It can improve the product quality, prolong the service life, and recover the economic loss of waste parts. There are significant economic and social benefits. Therefore, the industrial departments attach great importance to the thermal spraying technology.

Surface engineering is one of the key technologies of industrial development in the 21st century. Surface technology is divided into three categories: surface modification technology, film technology and coating technology. Thermal spraying technology is a very important technology in surface engineering, accounting for about 1/3 of surface engineering technology. And thermal spraying technology is very important in the area of surface engineering technology, accounts for about a third of the surface engineering technology, is developed abroad in the 50 s of a mechanical parts repair and protection of new technology. It can prolong the service life of all kinds of machinery and equipment and make the scrapped parts "come back to life". Thermal spraying technology is a cross - edge science of metal, polymer, surface physics, surface chemistry, fluid mechanics, heat transfer, plasma physics and computer science in terms of subjects.

Thermal spraying technology has two main characteristics: first, the composition of the powder is not limited, and can be selected according to special requirements; Second, the temperature of the workpiece can be controlled in the process of thermal spraying, thus reducing the deformation oxidation and phase change, so that the properties of the material cannot be damaged or lost. These characteristics and special functions of thermal spraying coatings have such as heat resistance, corrosion resistance, wear resistance, oxidation resistance, insulation and insulation, made the thermal spraying technology developed rapidly. When choosing a coating technology, we should take into account the economic and technical performance of the coating technology, and consider the surface coating or other surface modification and treatment in the whole system. We need to know the function of the surface requirements and service environment, base material (alloy, heat treatment, etc.) on the surface of the processing performance, also need to consider the coating's own technical problems and economy and the service life of coating and advantages, rather than just the production cost of coating.
