Abstract

The invention discloses a method for preparing a high-bonding-strength carbide coating on a diamond surface through microwaves, relates to a method for preparing a coating on the diamond surface. and aims at solving the problems that a carbide coating prepared on the diamond surface through an existing method is not uniform, difficult in thickness control and low in bonding strength. The method comprises the following steps: weighing diamond powder with a metal coating; performing ultrasonic oscillation treatment and drying on the diamond powder, carrying out microwave treatment on the diamond powder under the protective atmosphere, then cooling the diamond powder to the room temperature along with a furnace to obtain diamond powder with the surface coated with the carbide coating, and performing cleaning and drying to obtain the diamond powder. According to the method, the diamond plated with the metal coating is treated through microwaves, the compact carbide coating is generated within a short time, firm chemical bonding combination is achieved between the carbide coating and a diamond matrix, graphitization of the diamond is avoided. The method is simple in process, energy-saving and environment-friendly, reduces the coating cost, is wide in application range and can realize industrial production and application easily. The method is suitable for preparing the coating on the diamond surface.

Description

technical field [0001] The invention relates to a method for preparing a coating on a diamond surface. Background technique [0002] Diamond has the characteristics of high thermal conductivity, low density, and low expansion, making it an ideal reinforcement for lightweight, ultra-high thermal conductivity metal matrix composites. However, diamond and copper do not react or wet, and it is difficult to form a low thermal resistance, high-strength interface bond; diamond and aluminum are also weakly bonded, and easily hydrolyzed Al will be generated at the interface when the preparation temperature is high. 4 C 3 phase, reducing the reliability of the material. Introducing a suitable interfacial transition layer on the diamond surface can effectively improve the wettability between the diamond and the base metal, and at the same time avoid Al 4 C 3 The generation of hydrolytic phase is an effective means of modification. Common coatings include W, Ti, Cr and other metal c...
