A PREPARATION METHOD AND MACHINED PARTS FOR CERMETS

The invention discloses a metal ceramic preparation method and a machined part. The preparation method comprises the following steps of: taking metal as a matrix, firstly combining wear-resistant ceramic on the matrix through a special high-strength composite medium for ceramic, and then heating and drying to obtain the metal ceramic. The metal alloy and the ceramic are compounded, the preparation operation is simple, and the wear resistance of an alloy matrix is improved by utilizing the wear resistance of the ceramic. According to the machined part prepared through the method, the high-strength alloy serves as a matrix, the abrasion-resistant ceramic serves as an abrasion-resistant part, a firm composite body is prepared through the special composite medium for ceramic, the bonding force is high, the wear resistance is high, and the service cycle and the service life of the machined part can be greatly prolonged.
