Abstract

The invention discloses a anti-carburizing coating for heat treatment, which comprises the following components in percentage by weight: 15%-30% of boric acid, 8%-20% of titanium dioxide, 6%-10% of lithium bentonite, 3%-15% of kaolin, 3%-5% of ethanol, 3%-5% of chrome yellow, 3%-5% of sodium carboxymethyl cellulose, 3%-10% of maleic acid, 1%-5% of triethanolamine, 0.5%-3% of zinc chloride, 0.5%-1%of ferrous sulfate, and the balance of deionized water. The invention relates to the technical field of anti-carburizing coatings. The anti-carburizing coating for heat treatment has a very good anti-carburizing effect and can effectively prevent carbon atoms from permeating into the surface of a workpiece, so that a carburizing layer is not generated on the surface of the workpiece in a carburizing atmosphere, and an anti-carburizing coating layer formed after the anti-carburizing coating is brushed on the surface of the workpiece is good in cohesiveness and sealing performance, does not peel, flow or influence the carburizing atmosphere at high temperature, and can be washed and removed after heat treatment.

Description

technical field [0001] The invention relates to the technical field of anti-carburization coatings, in particular to a heat-treated anti-carburization coating. Background technique [0002] Anti-carburizing coating is a partial protective coating used to prevent the infiltration of carbon elements in certain parts when metal is subjected to chemical heat treatment. It is a common metal heat treatment anti-seepage coating for metal heat treatment protective coatings. Such fillers, pigments, and solvents are composed of ceramics, silicon chromate, aluminum borate, boron oxide, copper oxide, nickel oxide, glass frit and other anti-carburizing coatings. [0003] The existing heat-treated anti-carburization coating has poor anti-seepage effect during use, and is inconvenient to remove after heat treatment. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the present invention provides a heat-treated anti-ca...
