SiC coating by painting / spraying

Silicon Carbide is a ceramic compound, that is chemically inert and very hard. The coating is stable up to medium temperatures (withstands up to 1000 °C on air/in oxidizing atmosphere). The hardness of SiC gives the coating high resistivity against abrasion.

Main advantages:

  • Extends lifetime of graphite parts
  • Provides a hard surface, resistant to abrasion
  • Endures repeated heating cycles, and has its best performance above 700 °C. It creates a sealed surface of the graphite which stops oxidation
