Metal material and preparation method and application thereof

Abstract

The invention discloses a metal material, and a preparation method thereof and a metal material product. The metal material comprises the following components in parts by weight: 35-42 parts of nickel, 15-20 parts of cobalt, 1-3 parts of silver, 25-30 parts of titanium, 0.5-3 parts of tantalum and 0.1-0.3 part of niobium. According to the preparation method of the metal material, a colloid impregnation method and a powder metallurgy method are combined, the defects that titanium alloy is poor in oxidation resistance and thermal conductivity at the high temperature and has strict requirements for energy input in the forming process are overcome, the metal material has good fatigue resistance, corrosion resistance and comprehensive mechanical performance by adding cobalt, tantalum and niobium, and the metal material is suitable for large-scale production. Meanwhile, due to good biocompatibility, high mechanical strength and fatigue resistance and addition of a proper amount of silver element, a certain broad-spectrum sterilization or bacteriostasis effect is achieved while the basic mechanical property is guaranteed, the bacterial infection problem of the titanium alloy surgical implantable instrument is effectively solved, and the surgical implantable instrument is worthy of popularization and application. Metal material products made of the metal material can be widely applied to the medical fields of dental prostheses, joints, spines, trauma and the like.

Description

technical field [0001] The invention relates to the field of metal composite material preparation, in particular to a composite metal material preparation and a preparation method and application thereof. Background technique [0002] With the continuous advancement of science and technology, it is difficult for a single material to meet the needs of modern industry for the comprehensive performance of materials. Due to its designability, composite materials have attracted more and more attention from the industry. [0003] Due to its unique chemical and mechanical properties and good biocompatibility, titanium-based alloy materials are mainly used in aerospace and biomedical fields. They are alloy materials commonly used in technology, but titanium alloys have poor oxidation resistance at high temperatures. , the forming atmosphere needs to be strictly controlled; at the same time, the thermal conductivity of titanium alloy is poor, and there are strict requirements for ene...

Problems solved by technology

However, as biomedical materials, traditional metal materials still have unavoidable deficiencies in the following aspects: the metal prosthesis-bone interface bonding problem, the surface of the prosthesis is smooth, and the long-term fixation effect is not good; most surface modified layers are generally better than the surface The coating is thick and its performance gradually changes in a gradient, with a higher load-carrying capacity than the surface coating
