Abstract

The invention belongs to the field of medical materials and discloses a medical metal ceramic material and a preparation method thereof. The medical metal ceramic material comprises 11-15 parts of zirconium oxide, 13-17 parts of titanium dioxide, 2-4 parts of nickel, 6-11 parts of magnesium silicate, 3-7 parts of cobalt, 2-4 parts of magnesium, 3-6 parts of tungsten silicide,2-4 parts of aluminum carbonate and 4-8 parts of calcium metasilicate. The preparation method comprises the following steps: (1) respectively ball-milling the metals and a ceramic material; (2) pouring into a high-speed mixture and mixing at a high speed; and (3) sintering in vacuum at a high temperature, firstly heating the inside of a high-temperature sintering furnace to the temperature of 725-755 DEG C, heating the inside of the high-temperature sintering furnace again to the temperature of 980-1220 DEG C, sintering for 2.5-3.5 hours, and cooling the metal ceramic material inside the high-temperature sintering furnace to room temperature to obtain the medical metal ceramic material.

Description

technical field [0001] The invention belongs to the field of medical materials, and relates to a cermet material and a preparation method thereof, in particular to a medical cermet material and a preparation method thereof. Background technique [0002] Cermet material is a material formed by high temperature treatment process, so it has the dual advantages of metal and ceramics: (1) Because it is sintered at high temperature, its structure includes ionic bonds or covalent bonds with strong bonds , so it has good mechanical strength, hardness, high compressive strength, and is extremely stable; it is difficult to dissolve in the body, not easy to oxidize, not easy to corrode and deteriorate, good thermal stability, easy to heat and disinfect, wear-resistant, has certain lubricating properties, and is not easy to produce fatigue phenomenon , and has good affinity with human tissue, and almost no repulsion with human tissue can be seen, so it can meet the requirements of impla...
