New Development of Thermal Spray Technology

       【Summary】:

With the continuous improvement and perfection of thermal spraying technology, its application fields continue to expand. Modern plasma spray technology uses computer control systems, which greatly reduces the work intensity and reduces the error rate. The emergence of high-power plasma spraying technology has further improved the deposition efficiency of plasma spraying, and the spraying power has reached 200KW. In recent years, reactive spraying technology has been developed, that is, the chemical reaction between the components of the spraying material or between the spraying material and the spraying gas during the spraying process is used to synthesize coatings of special components in-situ. The materials used in thermal spraying have also developed with the development of thermal spraying technology, such as the use of high-temperature self-propagation.

The materials used for thermal spraying have also developed with the development of thermal spraying technology. For example, high-temperature self-propagation technology is used to prepare new spraying powders. Ceramic powder materials such as TiC, TiB 2 , and ZrB 2 have been synthesized. Ceramic powder materials such as TiC, TiB 2 and ZrB 2 have been synthesized.



The development of thermal spraying technology in the future may mainly develop in the following aspects: (1) The development of new spraying materials, and nanomaterials will become a hot spot for development; (2) The development of new fields of thermal spraying technology, such as combining thermal spraying technology with heat treatment technology (3) vigorously promote the application of computer in thermal spraying to realize programmed operation.
