Abstract

The invention discloses a titanium metal ceramic preparation process. According to a technical scheme: an hierarchical carburizing technology is employed to conduct surface high temperature carburizing on Ti6Al4V alloy to prepare titanium carbide ceramics on the surface and form a thick carburized layer, thus preparing the titanium alloy metal ceramic with superior biological friction performance and affinity performance. The process provided by the invention is characterized in that: the hierarchical carburizing technology is employed to conduct surface high temperature carburizing on Ti6Al4V alloy to prepare titanium carbide ceramics on the surface and form the thick carburized layer, thus preparing titanium metal ceramics.

Description

technical field [0001] The invention discloses a preparation process of titanium metal ceramics. Background technique [0002] At present, Ti6Al4V alloy, also known as TC4 titanium alloy, is the most widely used in the field of orthopedic surgery, which has high corrosion resistance, good biocompatibility, high mechanical strength and good processing performance. However, the poor tribological properties of titanium alloys greatly limit its further widespread use in artificial joints. [0003] In order to overcome the above problems, the present invention adopts a gas carburizing process to carry out surface carburizing treatment on Ti6Al4V alloy to prepare titanium alloy cermet. The preparation of titanium cermets has excellent nanomechanical properties, corrosion resistance, mechanical properties and biotribological properties, which lays the foundation for the wide application of titanium alloy cermets in biomedicine, especially in the field of artificial joints, and pro...
