Preparation method of metal ceramic brake pad and carbon ceramic brake disc and friction pair coupling
The invention provides a preparation method of a metal ceramic brake pad, a preparation method of a carbon ceramic brake disc and a friction pair coupling. The preparation method of the brake pad comprises the steps that MAX-phase ceramic powder and strengthening powder are sequentially subjected to mixing, pressing, sintering, resin impregnation, curing and carbonization treatment, and a metal ceramic blank is obtained; and the metal ceramic blank is machined and welded in sequence, and the metal ceramic brake pad is obtained. The preparation method of the brake disc comprises the following steps: sequentially carrying out pre-heat treatment, chemical vapor deposition treatment, resin impregnation, curing, carbonization treatment, post-heat treatment, primary machining, melting siliconizing treatment, secondary machining and assembling on the carbon fiber preform to obtain the carbon ceramic brake disc. The friction pair coupling part comprises the metal ceramic brake pad obtained through the preparation method and the carbon ceramic brake disc. The friction pair coupling is good in tribology matching performance, low in friction coefficient, stable in braking and excellent in abrasion resistance, and the basic braking requirement of the high-speed rail with the speed of 400 km or above per hour is met.
