Lot of metal components due to corrosion and wear failure, resulting in a great waste and loss of doob tubes wholesale some industrialized countries, according to statistics, the annual loss due to corrosion and wear steel caused about 10% of seamless steel pipe  production, the amount of loss of national economic output accounted for about 2 - 4%. If downtime due to metal corrosion and wear and tear caused by the shutdown and consequential injury, fire, accidents and other losses included in the statistics, then its value even more amazing with the development of cutting-edge science and modern industry, the industrial sector increasingly. The more long-term stability of machinery and equipment required to run at high parameters (temperature, high pressure, high speed and highly automated) and poor working conditions (such as severe wear and corrosion).

Therefore, the material properties also put more high demand. using high-performance advanced materials manufacturing equipment and spare parts to get the whole surface protection and strengthening effect, is obviously not the economy, and sometimes even impossible. Therefore, the research and development of materials Surface treatment technology would have significant technical and economic significance. The surface treatment technology is driven by this demand gained rapid development and improvement. Thermal spray technology is one such surface protection and enhanced technology, surface engineering is an important subject in the so-called thermal spraying is using a heat source such as arc, plasma arc, flame, or the like powdered metals and non-metallic filamentary coating material is heated to a molten or semi-molten state, and powered by the flame itself or in addition to the flow of high velocity gas atomization and to a certain speed to form a jet technology has a variety of functions through the surface of the overlay coating pretreated substrate surface, combined with the matrix material.

With the development of cutting-edge science and modern industry, the industrial sector increasingly require mechanical devices to high parameters (temperature, high pressure, high speed and highly automated) and poor working conditions (such as severe wear and corrosion) Under long-term stable operation. Consequently, the performance of the material also put forward higher requirements. using high-performance advanced materials manufacturing equipment and spare parts to get the whole surface protection and strengthening effect, is obviously not the economy, and sometimes even impossible . Therefore, the research and development of materials for surface treatment technology would have significant technical and economic significance. The surface treatment technology has gained rapid development and improvement driven by this demand.
