What are the properties and application characteristics of silicide ceramics

       Silicide is hard and brittle at room temperature, and becomes plastic at high temperature, and the bar can be bent and formed. The only silicide with wear resistance is chromium silicide (Cr3Si).



      The melting point of chromium silicide is 1660°C to 1760°C, and the hardness is HV1005. It has good high temperature oxidation resistance, high high temperature hardness, good wear resistance and good thermal shock resistance. It is oxidized when heated to above 1050 degrees Celsius in the air. It can be used for heat-resistant oxidation coating and acid corrosion-resistant coating.

      Coatings can be prepared by spraying processes such as gas-stabilized plasma spraying, supersonic flame spraying, and explosive spraying.
