Embodiment 1

[0041] The composition of the preparation is TiFe 2 Mo 17 mn 10 Nb 14 Zr 6 Ce 0.02 Dental titanium alloy

[0042] Take grade 1 sponge titanium, reduced iron powder, electrolytic manganese, industrial grade pure molybdenum powder, grade 1 sponge zirconium and industrial pure niobium, by mass percentage Ti:Fe:Mo:Mn:Nb:Zr:Ce=50.98:2:17 : 10: 14: 6: 0.02 ingredients, put each raw material into a vacuum non-consumable electrode water-cooled copper crucible electric arc furnace. Vacuumize the water-cooled copper crucible electric arc furnace with non-consumable electrodes to 5×10 -3 Pa, and filled with 99.999% pure argon. The pure titanium that comes with the furnace is melted to remove the oxygen in the vacuum chamber before melting the invented alloy. The current used during smelting is 300A to 500A. After melting, add electromagnetic stirring for 10 to 20 seconds, and then turn off the power to let the alloy cool down with the furnace. During the second smelting, the all...

Abstract

The present invention is one kind titanium alloy suitable for making false tooth. The alloy consists of Fe 1-3 wt% Mo 14-18 wt%, Mn 8-13 wt%, Nb 12-22, Zr 6-16 wt% and Ce 0.01-0.3 and the rest is Ti.Compared with available titanium alloy for stomalogical use, the titanium alloy of the present invention has improved biocompatibility, higher compression strength, higher hardness and higher wear resistance.

Description

technical field [0001] The invention relates to a titanium alloy material, in particular to a titanium alloy material suitable for manufacturing dentures. Background technique [0002] With the aging of the world's population, the demand for denture materials is increasing. Compared with other materials, titanium and titanium alloys have excellent biocompatibility, corrosion resistance, and high specific strength. Since the 1980s, developed countries have begun to study the application of titanium materials in oral restorations, and the research on titanium and titanium alloys has become a hot spot in the study of alloys for dental applications. Commonly used dental titanium alloys are mainly α+β type, such as Ti6Al4VELI, Ti6Al7Nb and Ti5Al2.5Fe, these alloys contain cytotoxic elements and elastic modulus that are not suitable for teeth. Compared with α+β-type titanium alloy, β-type titanium alloy has an elastic modulus closer to that of teeth, which is beneficial to reduc...
