Abstract

The invention discloses a composite material coating. The composite material coating is manufactured by piling of three coatings, wherein a second coating is used as an interlayer of a first coating and a third coating; the first coating is adhered to the outer surface of mechanical parts and components; the third coating is exposed; the first coating is a coating which is jointly sprayed and prepared from metal materials the same as that of the metal parts and components and ceramic powder; the second coating is a coating which is jointly sprayed and prepared from ceramic powder and an alloy;and the third coating is the coating which is jointly sprayed and prepared from any kind or the combination of two kinds of 2,4-diaminophenoxyethanol hydrochloride, N, N-bis (2-hydroxyethyl)-P-phenylenediamine sulfate or 4,5-diamino-1-(2-hydroxyethyl) pyrazole sulfate. The invention also discloses a preparation method of the composite material coating. Through the adoption of the technical schemeof the composite material coating disclosed by the invention, super-thick coating can be prepared, and is acid proof, alkali proof and salt proof, and a coating of which the surface color is florid can be prepared.

Description

technical field [0001] The invention relates to a coating, in particular to a composite material coating and a preparation method thereof. Background technique [0002] With the development of surface modification technology, and the application environment of surface sprayed functional coatings such as thermal barrier coatings, wear-resistant coatings, corrosion-resistant coatings, and insulating coatings is becoming more and more harsh. The research on the performance of composite coatings in harsh environments has gradually become the focus of research. The performance of traditional single-layer coatings in all aspects cannot meet the requirements of harsh environments. Therefore, spraying multi-layer coatings with different components on the surface of the substrate can improve the reliability of working under high-speed, high-temperature, high-pressure, heavy-duty, and corrosion conditions, relatively effectively protect the surface of the workpiece, and improve the a...
