Embodiment Construction

[0020] The present invention will be further described below in combination with specific embodiments. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0021] A melt-spraying coating method of the present invention sprays molten coating metal powder onto a preheated base metal material, accumulates layer by layer, and after cooling, the coating metal powder forms a metal coating and coats the surface of the base metal material.

[0022] Wherein, the coating metal is an alloy metal, usually alloy materials such as tungsten carbide alloy can be used, and the base metal is...

Abstract

The invention provides a molten spray coating method, which comprises the following steps of: spraying molten coating metal powder to a preheated matrix metal material, stacking layer by layer; and after cooling, forming a metal coating on the surface of the matrix metal material by the coating metal powder. The invention also provides an excavating tooth, which consists of a carbon steel excavating tooth body and an alloy tooth crest coating. The carbon steel excavating tooth body comprises a tooth pole and a tooth crest; and the alloy tooth crest coating coats the tooth crest. The method solves the problem that an alloy layer coated on the surface of a metal is thin in the prior art, and makes up for the defect that the service life is short in the prior art.

Description

technical field [0001] The invention relates to a melt blown coating method and tooth digging. Background technique [0002] More and more mines have begun to use mechanized operations to increase the mining rate of mines and eliminate potential safety hazards. The degree of mechanization in mines such as coal mines, copper mines, and zinc mines has been greatly improved, greatly enhancing the market capacity of mining machinery and equipment. An excavator, also known as an excavator, is an earth-moving machine that uses a bucket to excavate materials that are higher or lower than the bearing surface, and load them into transport vehicles or unload them to the stockyard. The excavated materials are mainly soil, coal, silt, and pre-loosened soil and rock. Judging from the development of construction machinery in recent years, the development of excavators is relatively fast, and excavators are one of the most important types of construction machinery in engineering construc...
