Thermal spraying technology has many characteristics, and various coatings prepared by thermal spraying technology have many unique advantages. There are mainly the following points;
(1) A wide range of materials can be sprayed. Including all kinds of metals and alloys, ceramics, cermet, intermetallic compounds, non-metallic minerals, plastics and other solid engineering materials, thus can prepare a variety of protective coatings and functional coatings, Such as wear resistant, anti-friction self-lubrication, wear sealing, friction resistance, corrosion resistance, oxidation resistance, high temperature resistance, thermal barrier, insulation, conductivity, superconductivity, radiation, radiation protection, shielding, anti-interference, wavelength absorption, catalysis and biological function coating.
(2) It can be developed into coatings on a variety of substrate materials. These include metals, ceramics, plastic substrates, gypsum, wood and even cardboard. The range of substrate materials being sprayed is very wide.
(3) Yixiu is not limited by the workpiece size and construction site, can spray large heavy workpiece, but also can spray small parts, thin wall parts; It can be constructed in the factory or on site.
(4) High deposition efficiency, especially suitable for the deposition of thick film coating. Compared with electroplating, electroless plating, ion plating, vapor deposition and other technologies, thermal spraying has a higher deposition rate, higher production efficiency, and the coating thickness can be controlled, from tens of microns to several millimeters, or even thicker.
(5) the thermal effect on the base material is small. Compared with thermal diffusion infiltration plating, vapor deposition, high temperature synthesis, sintering and other processes, except spray welding, thermal spraying has little thermal influence on the matrix, and the matrix heating temperature is generally not more than 200 degrees, so the matrix materials will not change the structure, properties, and deformation.
(6) It is easy to adjust the coating composition. The composition and properties of coating can be easily adjusted by adjusting the type, proportion and coating technology of coating materials.
(7) It is easy to locally strengthen or modify the product. It can be sprayed locally on products to achieve local surface strengthening and modification. It can also produce thin - walled parts, hollow parts and complex - shaped parts without matrix by demoulding.
(8) Save valuable materials. On the premise of meeting the strength requirements, the matrix material can choose more common materials instead of the valuable whole material, only the surface coating with precious materials.
(9) Convenient maintenance. Thermal spraying operation is flexible, the process is relatively simple, strong adaptability, widely used in the maintenance of various equipment and components. After the coating is damaged, it can be removed and repaired by spraying again, and the base material can be fully utilized.
