Diamond (diamond) is the hardest substance in the world, with a hardness of up to 10000 HV. Diamond coatings grown using related CVD technology have many excellent properties that cannot be compared to other materials. It has natural diamond like hardness and elastic modulus, extremely high thermal conductivity, excellent chemical stability, and optical properties. These excellent characteristics make it widely used in fields such as tool coating and semiconductor manufacturing

Chemical vapor deposition (CVD) technology is a technique that uses various energy sources such as heating and light radiation through chemical reactions to form solid deposits of diamond from gaseous chemical substances in a reactor. The Swiss NeoCoat diamond coating equipment used by Kehui uses HFCVD (Hot Filament CVD) technology, which decomposes substances through heating.
