Abstract

A biological bone composite material and a preparation method thereof belong to the field of material technology. The composite material is composed of CoCrMo alloy powder, CeO2 alloy powder and ZrO2 alloy powder; among them, in terms of mass percentage, CoCrMo alloy powder: CeO2 alloy powder: ZrO2 alloy powder = (92~98): (1~3): (1 ~5); CoCrMo powder particle size ranges from 100 to 200 mesh, CeO2 powder particle size ranges from 0.5 to 1 μm, and ZrO2 powder particle size ranges from 30 to 80nm. All three powders are spherical in shape. The preparation method is: (1) mixing of composite powder; (2) matrix material pretreatment for laser direct deposition forming; (3) laser direct deposition forming process method, using laser 3D printer, inert gas protection; laser continuous scanning n The layer returns to the origin coordinates of the XY plane. The composite material has good strength, toughness, wear resistance and corrosion resistance; the hardness reaches 619HV and the tensile strength reaches 686MPa; after being soaked in artificial simulated saliva for seven days, the Cr ion concentration is 0.11mg / L. Composite materials are used in the preparation of artificial bone dentures.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a bio-bone composite material and a preparation method thereof. Background technique [0002] With the gradual improvement of people's living standards and the rapid development of modern science and technology, people's attention to the quality of life in modern life and the health of the human body is also increasing year by year. For diseases, natural disasters, sudden accidents, natural aging, etc. Tooth loss or fractures caused by various factors occur frequently. Under the premise of being non-toxic and harmless and ensuring good biocompatibility, dentures made of different materials with excellent mechanical properties such as good wear resistance, high corrosion resistance, and sufficient hardness, which are prepared and put into clinical application, are the world's leading dentures. One of the research hotspots in this field. Since Co-Cr-based alloys hav...
