The development of China's thermal spray technology industry has multiple opportunities

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



The industry analyst of Shangpu Consulting pointed out that the main connotation of thermal spraying technology should include three aspects: material, equipment and process (including pretreatment, spraying process, and post-processing). The initial thermal spraying can only use metal wire with a lower melting point as the material, and use the flame as the heat source to spray anti-corrosion coatings and perform maintenance services, so it is called "metal spraying". The advent of self-fluxing alloy powders during World War II enabled powder flame spraying to gain 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 advent of atmospheric plasma spraying technology. The successful development of self-adhesive composite powders 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 technologies such as explosive spraying, low-pressure plasma spraying, and supersonic flame spraying, the realization of high-quality coatings has become possible, and thermal spraying materials for various purposes have emerged accordingly. For a long time, thermal spraying equipment and processes have been pursuing high energy of heat source and high speed of particles, and pursuing high efficiency of spraying process through operation automation, and finally improving the quality and stability of coating. Over the past century, thermal spray materials have developed from several metal wires to hundreds of thermal spray materials to meet the needs of different process operations and different use characteristics. The thermal spraying material obtains a coating with a certain composition and structure through the spraying method (equipment, process), and then obtains the desired coating characteristics. In a broad sense, thermal spray technology is a means of material compounding. It can be said that the functional diversity of thermal spray coatings or their adaptability to different specific uses depends on the material. The development of thermal spray materials and spray methods promote each other, and together they promote the progress of the entire thermal spray technology.



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



Sales revenue and growth of my country's thermal spraying industry from 2011 to June 2014



The current high-speed, stable and healthy development of my country's economy is the best stage of economic development since the founding of the People's Republic of China. As a high-tech industry and a multidisciplinary cross-border technology, thermal spraying is extremely sensitive to the development status of the national economy, especially the development status of the manufacturing industry and the adjustment of product structure, and has a strong dependence. Therefore, under such 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 thermal spraying industry in Chengdu. The most professional and first-class surface technology continues to grow and develop.



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