Novel composite coating of diamond applied to stone cutter

Abstract

The invention provides a preparing technology of a surface hydrothermal composite titanizing and tungsten plating metal layer of the diamond applied to a stone cutter, and belongs to the technical field of diamond surface plating metal layer film preparing. The low-temperature pressure plating and high-temperature thermal treatment technology is achieved, the continuity and uniformity of an obtained film are good, the shape is regular, the thickness is controllable, the strength of the diamond is improved, and the anti-corrosion capability and bonding performance under the high temperature are improved. The service life of the manfuactured cutter during stone cutting is greatly prolonged, the efficiency of the manufactured cutter during stone cutting is greatly improved, and economic benefits are obvious. The preparing method is simple and low in cost, and large-scale production is easy to achieve. Thus, the technology method has very wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of film preparation of metal layer coated on diamond surface, and in particular relates to a preparation process of hydrothermal composite titanium and tungsten metal layer coating on diamond surface. Background technique [0002] Diamond itself not only has excellent properties such as high hardness, corrosion resistance and wear resistance, but also has excellent optical, acoustic, thermal and electrical properties. For more than half a century, the production and application technology of artificial diamond has developed by leaps and bounds, and its quantity, quality and many properties have reached or even surpassed that of natural diamond. Diamond and its products are not only widely used in various industrial and technical fields such as machinery, metallurgy, construction, transportation, and national defense, but also have been expanded to important fields such as high-performance heat-resistant part...

AI Technical Summary

Problems solved by technology

[0006] In order to obtain the ideal metal coating layer on the diamond surface, various methods can be used, such as the combination of chemical plating and electroplating, vacuum plating, salt bath plating, vacuum physical vapor plating and physical chemical vapor plating, etc., but these plating The method generally has problems such as uneven plating, weak bonding between the plating layer and the diamond, low single plating amount, difficulty in controlling the plating thickness, and high cost.

Among them, the vacuum micro-evaporation plating method developed by Yanshan University can realize the process of plating Ti as low as 650°C, but the atom diffusion ability is limited at low temperature, and the formed coating is thin, which is difficult to meet the actual needs.
