Abstract

The invention discloses a composite material coating, which comprises the superposition of three layers of coating, the second layer is used as the interlayer between the first layer and the third layer, the first layer is attached to the outer surface of mechanical parts, and the third layer is exposed , the first layer is a coating prepared by co-spraying the same metal material as the metal part material and ceramic powder, the second layer is a coating prepared by co-spraying ceramic powder and alloy, and the third layer is a coating prepared by using 2,4-two Aminophenoxyethanol hydrochloride, N,N-bis(2-hydroxyethyl)-p-phenylenediamine sulfate or 4,5-diamino-1-(2-hydroxyethyl)pyrazole sulfate Any one or a combination of the two are sprayed together to prepare the coating. The invention also discloses a preparation method of the composite material coating. By adopting the technical scheme of the invention, an ultra-thick coating can be prepared, which is resistant to acid, alkali, and salt, and can prepare a coating with brilliant surface color.

Description

Technical field [0001] The present invention relates to a coating, particularly a composite coating and a preparation method thereof. Background technique [0002] With the development of surface modification techniques, as well as the surface spraying of functional coatings such as thermal barrier coating, wear-resistant coating, corrosion-resistant coating, and insulating applications are getting worse. The study of composite coating performance in harsh environments has gradually become the focus of research. The performance of all aspects of the conventional single-layer coating is not applied to the needs of harsh environments. Therefore, the multilayer coating of different components is sprayed in the surface of the matrix to improve the reliability of high speed, high temperature, high pressure, overload, corrosion conditions, relatively effective protective workpiece surface, and to withstand the repeated load capacity. Key Techniques for Surface of Mechanical Parts Surfa...
