Carbon-ceramic crucible for siliconizing carbon-ceramic brake disc and preparation method of carbon-ceramic crucible
The invention relates to the technical field of thermal field components for siliconizing of carbon-ceramic brake discs. The invention discloses a carbon-ceramic crucible for siliconizing a carbon-ceramic brake disc and a preparation method of the carbon-ceramic crucible. The preparation method comprises the following steps that S1, fiber carbon cloth and a net tire are alternately stacked to form composite cloth, the composite cloth is attached to a mold, needling is conducted, and a crucible prefabricated body is prepared; s2, performing carbon-carbon densification on the crucible preform by adopting chemical vapor deposition to prepare a carbon-carbon crucible preform; s3, performing heat treatment on the carbon-carbon crucible preform to obtain the carbon-carbon crucible; s4, carrying out finish machining on the carbon-carbon crucible; and S5, a silicon material is flatly laid at the bottom in the carbon-carbon crucible after finish machining, melting siliconizing is carried out, and the carbon-ceramic crucible for siliconizing of the carbon-ceramic brake disc is prepared. The carbon-ceramic crucible for siliconizing of the carbon-ceramic brake disc is prepared by the preparation method. The prepared carbon-ceramic crucible for siliconizing of the carbon-ceramic brake disc is high in wear resistance, high in strength, long in service life and low in cost.
