Novel titanium-zirconium alloy material and preparation method thereof

Abstract

The invention discloses a novel titanium-zirconium alloy material and a preparation method thereof.The alloy material comprises, by weight, 20%-70% of titanium, 30%-80% of zirconium, 0.1%-25% of niobium and the balance inevitable trace impurities, and the total amount of the inevitable trace impurities is smaller than 0.4%; the preparation method of the novel titanium-zirconium alloy material comprises the following steps: taking titanium, zirconium and niobium in percentage by weight, mixing the titanium, the zirconium and the niobium, pressing into an electrode, and smelting in a consumable electrode vacuum furnace for two to three times to obtain an alloy ingot; the obtained alloy cast ingot is scalped, a dead head and a tail are cut off, a plate blank or a bar blank is manufactured through cogging forging, then rolling is conducted, and a plate or a bar is obtained; the obtained plate blank or rod blank is heated in the atmospheric environment, the obtained plate blank or rod blank can be heated in the atmosphere, a black protective film is formed on the surface, and the formed protective film has high hardness and abrasion resistance.

Description

technical field [0001] The invention relates to the field of alloy materials, in particular to a novel titanium-zirconium alloy material and a preparation method thereof. Background technique [0002] Because titanium, zirconium and their alloys have high tensile strength and yield strength, as well as low density, light weight, good inertness and hypoallergenicity, with the development of the national economy in recent years, titanium, zirconium and their alloys Materials are increasingly used in various civil fields, such as dentistry, orthopaedic implants, sporting goods, architectural decoration, etc.; [0003] With the increase in the application of titanium, zirconium and its alloy materials, people's requirements for the surface color of products are increasing day by day, among which black-based application scenarios are the majority; [0004] Electroplating or anodizing is currently the mainstream method to change the surface color of titanium, zirconium and its al...

Problems solved by technology

[0004] Electroplating or anodizing is currently the mainstream method to change the surface color of titanium, zirconium and their alloy materials. A thin layer of coating can be formed on the surface of the material through electroplating or anodizing, but the coating formed by these methods has poor wear resistance. , it is easy to scratch, and the process of electroplating or anodizing requires some chemical reagents, some of which are toxic and harmful to human health
