Problems solved by technology

[0005] The biggest difficulty in the preparation of three-dimensional ceramic-reinforced metal composites is the poor wettability between metal and ceramic due to the different bonding mechanisms between ceramic materials and metal materials
The first three methods usually require expensive equipment, complex process, poor plating performance, and high cost, so it is difficult to implement on a large scale; as far as electroless plating is concerned, electroless plating on ceramics requires a series of sensitization and activation processes on the ceramic surface , the solution stability is poor, maintenance, adjustment and regeneration are troublesome, and the cost is high. At the same time, there is no relevant research showing that the electroless plating method can be used to obtain a single Ti coating

Abstract

The invention discloses a method for preparing a titanium metal coating on a ceramic surface. The method for preparing the titanium metal coating on the ceramic surface comprises the following steps of: firstly, placing ceramic the surface of which is treated into a quartz tube; then placing a mixture of titanium powder and iodine powder into a container, and placing the container into the quartz tube; then placing the quartz tube into a program control furnace, vacuumizing the program control furnace repeatedly, and introducing an inert gas, warming the program control furnace at the warming speed of 15-20 DEG C / min to 1030-1200 DEG C and carrying out heat preservation, and cooling, thereby obtaining the ceramic the surface of which is coated with the metal coating. The coating provided by the invention is high in purity, and has strong bonding force with base body ceramic, is uniform in distribution on the whole ceramic plane, can form a smooth deposition surface easily; and the device is simple, low in cost and simple to operate.

Description

technical field [0001] The invention belongs to the technical field of treating ceramics to metallize its surface, and relates to a method for treating ceramics to metallize its surface, in particular to a method for preparing a titanium metal coating on the surface of ceramics. Background technique [0002] With the rapid development of science and technology, the requirements for the comprehensive performance of materials are getting higher and higher, and materials with a single superior performance can no longer meet the needs of practical applications. Therefore, more and more attention has been paid to structural materials, functional materials or composite materials with integrated structure and function with excellent comprehensive properties. [0003] Metal composite materials have many advantages such as high specific strength, specific modulus, wear resistance, small thermal expansion coefficient, good high temperature performance, excellent thermal conductivity, ...
