The development of Chinese thermal spray technology industry has multiple opportunities

Thermal spraying technology is to use a certain heat source to heat or semi-melt the thermal spray material, and atomize it by flame flow or external high-speed air flow, and then spray it on the surface of the substrate (workpiece), and combine with the substrate to form a functional coating method. Thermal spraying technology creates a special working surface on the surface of ordinary materials to achieve: anti-corrosion, wear resistance, friction reduction, high temperature resistance, oxidation resistance, heat insulation, insulation, electrical conductivity, anti-microwave radiation, etc. Function to achieve the purpose of saving materials and energy. We call the special working surface coating, and the working method of manufacturing the coating is called thermal spraying. Thermal spraying technology is one of the important components of surface process technology, accounting for about one-third of surface engineering technology.

 

Shangpu Consulting industry analyst pointed out: The main connotation of thermal spraying technology should include materials, equipment and processes (including pretreatment, spraying process, post-processing) three aspects. The initial thermal spraying can only use metal wire with a lower melting point as the material, and flame as the heat source to spray anti-corrosion coatings and perform maintenance services, so it is called "metal spraying." During the Second World War, the emergence of self-fluxing alloy powder enabled powder flame spraying to obtain large-scale industrial applications. After the war, the aviation and aerospace industries developed rapidly, and high-melting-point metals or alloys and ceramic materials became practical with the emergence of atmospheric plasma spraying technology. The successful development of self-adhesive composite powder represented by nickel and aluminum has played an important role in further improving the bonding force of the coating.

 

With the improvement of spraying equipment and the subsequent development of new processes such as explosive spraying, low-pressure plasma spraying, and supersonic flame spraying, the realization of high-quality coatings is possible, and thermal spraying materials for various purposes have emerged accordingly. For a long period of time, thermal spraying equipment and processes have been pursuing the high energy of the heat source and the high speed of particles, and pursuing the high efficiency of the spraying process through operation automation, and ultimately improving the quality and stability of the coating. Over the past century, thermal spraying materials have developed from the original several metal wires to hundreds of thermal spraying materials that are required to adapt to different process operations and different use characteristics. The thermal spraying material obtains a coating of a certain composition and structure through spraying methods (equipment, process), and then obtains the required coating characteristics. In a broad sense, thermal spraying technology is a means of material compounding. It can be said that the variety of thermal spray coating functions or adaptability to different specific uses depends on the material. The development of thermal spraying materials and spraying methods promote each other, and the two together promote the progress of the entire thermal spraying technology.

 

From January to June 2014, the sales revenue of my country's thermal spray industry reached 3.271 billion yuan, a year-on-year increase of 25.6%. In 2013, the sales revenue of my country's thermal spray industry reached 6.047 billion yuan, a year-on-year increase of 14.5%.

The current rapid, stable and healthy development of my country's economy is the best stage of economic development since the founding of the country. Thermal spraying, as a high-tech industry and multi-disciplinary crossover, edge technology, is extremely sensitive to the development state of the national economy, especially to the development state of the manufacturing industry and product structure adjustment, and has a strong dependence. Therefore, in this economic situation, the annual growth rate of thermal spraying has been above 10% in the past five years.

 

Therefore, as a pioneer in the field of thermal spraying in the southwest region, our company is based on making the thermal spraying business stronger and bigger, and doing the best in the Chengdu thermal spraying industry. Chengdu thermal spraying, Chengdu plasma spraying and Chengdu surface technology, our company will The most professional and first-class surface technology continues to grow and develop.

 

Thermal spray technology is also used in many task industries. At present, the key customers of thermal spray technology are mainly concentrated in many domestic fields such as papermaking, machinery, electric power, transportation, construction, glass, aerospace, petrochemical, and light industry. The vast market area brings many opportunities for the development of the spraying technology industry.
