Embodiment Construction

[0020] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar extensions without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0021] As an embodiment of the present invention, a supersonic plasma spraying technique is used to prepare a titanium coating on the surface of a metal substrate. Supersonic plasma spraying technology is a kind of thermal spraying technology. It has the characteristics of high flame temperature and high flying speed of sprayed particles. It can spray a wide range of materials, dense coating, and high bonding strength with the substrate. Use plasma flame (non-transferred plasma arc) to heat the introduced spray powder to a molt...

Abstract

The invention relates to a method for spraying a titanium coating on a substrate. The method is characterized by comprising the following steps: performing substrate pre-processing to clear away oil and dust on the surface of the substrate; performing one-time or repeated spraying to prepare the titanium coating on the surface of the substrate. The titanium coating is sprayed by adopting a supersonic plasma coating method, and can be sprayed on the substrates such as steel, aluminum and aluminum alloy. Through the adoption of the titanium coating spraying technology, original titanium equipment can be made of steel, aluminum and aluminum alloy, and then is sprayed with a titanium coating, so that the titanium equipment has excellent corrosion resistance, and meanwhile, the manufacturing cost of the titanium equipment is reduced.

Description

technical field [0001] The invention relates to the field of material processing, in particular to a method for coating titanium on a substrate by supersonic plasma spraying technology. Background technique [0002] Due to its excellent corrosion resistance, mechanical properties and process properties, titanium is widely used in many sectors of the national economy. Especially in chemical production, titanium is used instead of stainless steel, nickel-based alloys and other rare metals as corrosion-resistant materials. This is of great significance to increase production, improve product quality, extend equipment life, reduce consumption, reduce energy consumption, reduce costs, prevent pollution, improve working conditions and increase labor productivity. Titanium metal has become one of the main anti-corrosion materials in chemical equipment, and has established its corrosion-resistant status in chemical equipment. At present, the application of titanium equipment has e...
