Embodiment 1

[0013] The alloy material is prepared from sponge titanium, sponge zirconium, and palladium powder. The design masses of each component are: titanium (Ti) 84.8 kg, zirconium (Zr) 15 kg, palladium (Pd) 0.15 kg. After pressing the electrode, carry out secondary vacuum arc self-consumption smelting. The ingot is opened at 900-1050°C and processed into alloy rods at 800-900°C. The total variation is controlled between 65-95%. Above-mentioned processing technology can be carried out by the method of prior art.

Embodiment 2

[0015] The alloy material is prepared from sponge titanium, sponge zirconium, and palladium powder. The design masses of each component are: titanium (Ti) 74.8 kg, zirconium (Zr) 25 kg, palladium (Pd) 0.2 kg. After pressing the electrode, carry out secondary vacuum arc self-consumption smelting. The ingot is opened at 900-1050°C and processed into alloy rods at 800-900°C. The total variation is controlled between 65-95%. Above-mentioned processing technology can be carried out by the method of prior art.

Embodiment 3

[0017] The alloy material is prepared with titanium sponge, zirconium sponge and palladium powder as raw materials. The design masses of each component are: titanium (Ti) 94.85 kg, zirconium (Zr) 5 kg, palladium (Pd) 0.15 kg. After pressing the electrode, carry out secondary vacuum arc self-consumption smelting. The ingot is opened at 900-1050°C and processed into alloy rods at 800-900°C. The total variation is controlled between 65-95%. Above-mentioned processing technology can be carried out by the method of prior art.

Abstract

The invention discloses an alloy, especially a bio-medical titanium alloy for teeth. The alloy is used for clinical oral rehabilitation, planting and remedy. The alloy is characterized in that the alloy consists of Ti, Zr, and Pd, wherein the content of the components is as follows (by weight): Zr:5-25%, Pd:0.1-0.2%, Ti: the rest. The alloy has the following advantages: 1. good biocompatibility : selecting Zr and Pd as the alloy elements; 2. Low elastic modulus (80-90Gpa); 3. excellent corrosion-resisting property: containing negative active constituent Pd; 4. good technological formability.

Description

technical field [0001] The invention relates to an alloy material, in particular to a dental biomedical titanium alloy, which is mainly used for clinical oral restoration, implantation, orthodontics and the like. technical background [0002] With the development of social economy, the improvement of national living standards and the aging of the social population, the demand for dental materials in the market is growing significantly. Clinical surveys show that the demand for titanium as a dental orthodontic, restoration, and implant material is growing at a rate of 20-30%, and it has become a new material with the most development and application prospects in dental metal materials. With a development history of more than 50 years, there are too few varieties of dental titanium alloys that can be provided for clinical use. Currently, commercial pure titanium and Ti6Al4V alloys are mainly used. The strength of pure titanium is still insufficient, and the strength of Ti6Al4...
