Abstract

The invention discloses a wear-resistant casting of a metal-based ceramic composite material and a processing technology thereof. The wear-resistant casting is prepared by processing the metal-based ceramic composite material; during processing, ceramic particles are used as a basis for modification treatment and mix the ceramic particles and the metal-based material through the mixing injection molding device. After the modified ceramic material and the metal-based material enter the injection molding reaction cylinder, the mixed material is stirred by the stirring blade at the bottom of the stirring rod, and the power motor Drive the stirring rod to rotate clockwise. When the stirring rod rotates clockwise, the mixed material in the injection molding reaction cylinder is first stirred by the stirring blade at the bottom, and the screw blade at the bottom will convey the mixed material from bottom to top, and the The upper spiral blade returns the mixed material moved to the upper part to the lower part, so that the material is fully mixed in the injection molding reaction cylinder. Compared with the traditional stirring method, the material can be mixed more uniformly.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a wear-resistant casting of a metal matrix ceramic composite material and a processing technology thereof. Background technique [0002] With the continuous development of modern industry, traditional iron and steel materials have been difficult to meet the needs of materials in the field of wear resistance. In the existing technology, metal matrix ceramic composite materials have both the hardness and wear resistance of ceramics and the toughness of metals to solve the problem. It solves the contradiction between high hardness and high toughness in traditional steel materials, and is widely used in many technical fields; [0003] Metal matrix ceramic composites are composite materials composed of metal materials with good toughness and ceramic materials with good hardness, but in the prior art, due to the poor dispersion effect of metal materials and ceramic ma...
