Abstract
The invention discloses a titanium alloy compound material for dental department and a preparation method thereof. The titanium alloy compound material for the dental department is prepared from the following chemical components in percentage by weight: 2 to 3 percent of Cu, 3 to 5 percent of Zr, 0.05 to 0.1 percent of Ce, 0.02 to 0.1 percent of Ag, 10 to 15 percent of graphene oxide fibers and the balance of Ti. According to the titanium alloy compound material for the dental department, graphene oxide is added so that the mechanical property is greatly enhanced; compared with an alloy matrix, the composite material provided by the invention has the advantages that the plasticity is greatly improved when the room-temperature strength of the composite material is improved, and the corrosion resisting performance of the titanium alloy compound material for the dental department is ensured; an inert gas protected stirring method is used for preparing mixed slurry of the graphene oxide and alloy powder, the interface bonding property of the graphene oxide and the alloy powder is improved, and oxidization of the alloy powder is avoided, so that the molding property of subsequent powdersintering is improved; a processing technology of the preparation method is simple, and the preparation method is easy to popularize in a large scale.
Description
technical field [0001] The invention belongs to the technical field of medical materials, in particular to a titanium alloy composite dental material and a preparation method thereof. Background technique [0002] According to statistics, periodontal disease, dental caries, and irregular dentition are the three most common dental diseases in my country at present. The various sequelae of these three dental diseases, such as tooth loss, gingival swelling and pain, and tooth extraction, also plague people, accounting for 90% of them. of people suffer from varying degrees of gingivitis and periodontitis. In the past, due to the restriction of the level of economic development and the concept and awareness of oral hygiene, the understanding and cooperation of early treatment and preventive treatment among the Chinese lagged behind that of developed countries. In recent years, with the improvement of people's living standards and the enhancement of patients' awareness of treatmen...
