A ceramic-based friction material

 A ceramic-based friction material refers to a friction material that adds a certain proportion of ceramic components or oxides with ceramic properties and exhibits partial ceramic properties as a whole. It is generally composed of ceramic fibers, iron-free filler substances, adhesives and a small amount of metal, and is a new type of friction material. At present, the research on ceramic tribology at home and abroad mainly focuses on a few ceramic materials such as SiC, Si3N4, Al2O3, BN and ZrO2. Among them, C/C-SiC composite materials and Al2O3 ceramic friction materials are the most widely used, and C/BN composite materials have more potential for development in friction materials.
