Our company provides SiC coating process services by CVD method on the surface of graphite, ceramics and other materials, so that special gases containing carbon and silicon react at high temperature to obtain high purity SiC molecules, molecules deposited on the surface of the coated materials, forming a SiC protective layer.
1. Résistance à l'oxydation à haute température:
the oxidation resistance is still very good when the temperature is as high as 1600 ℃.
2.
3. Résistance à l'érosion: dureté élevée, surface compacte, particules fines.
4. Résistance à la corrosion: réactifs acide, alcalin, sel et organique.
