Thermal spraying technology is a method of using a heat source to heat the sprayed material to a molten or semi-melted state, and spraying and depositing it on the pretreated substrate surface at a certain speed to form a coating. There are various process methods for thermal spraying, such as plasma spraying, arc spraying, flame spraying and explosive spraying.

Zirconium diboride (ZrB2) has high melting point, high hardness, high stability and good electrical conductivity, thermal conductivity, oxidation resistance and chemical resistance, which makes composite ceramics made of zirconium diboride as raw material excellent comprehensive performance. So zirconium diboride is very suitable for ultra-high temperature ablation resistant materials used in supersonic spacecraft and missile casings.

Nano-titanium diboride (Nano-TiB2) particle reinforced aluminum matrix composite material, TiB2/Al has excellent mechanical properties and physical properties such as high specific strength and specific modulus, wear resistance, fatigue resistance, low density, good dimensional stability, etc. Moreover, compared with continuous fiber reinforced composite materials, it has a significant low-cost advantage. The material is isotropic, easy to process, and flexible and diverse in preparation. It can be extruded, rolled and forged with traditional equipment.

Because carbon-carbon (C/C) composites have superior high-temperature thermophysical and mechanical properties than other materials, they are currently the first choice for solid rocket motor nozzle throat linings. During the working process of the engine, the C/C composite throat lining will be damaged due to the erosion and ablation of the heat flow of high temperature, high pressure, high speed and containing erosive particles under the harsh thermal environment, which is manifested as the expansion of the throat diameter. The surface is rough and uneven, the profile is irregular, etc., which affects the working pressure of the engine and reduces the efficiency of the nozzle.

Zirconium carbide has the characteristics of efficiently absorbing visible light and reflecting infrared rays. When it absorbs short-wavelength energy below 2μm, which accounts for 95% of sunlight, the energy can be stored in the material through thermal conversion. At the same time, it also has the ability to reflect infrared rays exceeding 2μm wavelengths.

B4C ceramic has the best protective performance, which is in line with the development direction of lightweight equipment. It is the most ideal bulletproof ceramic material. It is mainly used for the processing of high-end bulletproof inserts, especially the integrated multi-curved B4C ceramic bulletproof inserts. The highest level in the field of equipment.
