Problems solved by technology

Corrosion will reduce the strength, plasticity, toughness and other mechanical properties of metal materials, and then affect the geometric shape and physical properties of components, parts, equipment, etc. made of metal materials, shorten the service life, and even cause safety accidents
Corrosion of metals is very common, among which the corrosion of iron products, the most used metal, is the most common. To deal with metal corrosion, one is to change the structure of metal materials by doping elements, and the other is to use electrochemical cathodes and The third method of anodic protection is to add organic coatings and non-metal oxide coatings on the metal surface. The main anti-corrosion methods for steel wires are galvanizing and grease coating, but the galvanized steel wires are easy to react with mortar. , poor adhesion between grease and steel wire, etc., its anti-corrosion performance cannot meet the high actual demand

Abstract

The invention discloses a molybdenum disulfide anticorrosive coating based on electrochemical deposition and a preparation process thereof. The molybdenum disulfide anticorrosive coating comprises anelectroplating reactant, a solvent and an auxiliary agent, wherein the electroplating reactant comprises the components of, in parts by weight, 27-41 parts of molybdenum pentachloride, and 6.5-9.6 parts of elemental sulfur, and the solvent comprises the components of, in parts by weight, 65-75 parts of pure water and 25-35 parts of ethylene glycol. According to the molybdenum disulfide anticorrosive coating, the components of the anticorrosive coating and the preparation process are arranged, so that molybdenum disulfide crystal grains in the coating are of a fullerene structure, the added auxiliary agent is partially inserted between molybdenum disulfide layers, carbonized at high temperature, and promotes formation of the fullerene structure, and mutual dissolution between metal zinc andmetal aluminum in modified graphite promotes and improves the lubricating property, the corrosion resistance and the mechanical property of the coating, so that the comprehensive performance of the coating is improved while the corrosion resistance function of the coating is realized, and the coating is suitable for wide popularization and application.

Description

technical field [0001] The invention relates to the field of electrochemical coatings, in particular to a molybdenum disulfide anticorrosion coating based on electrochemical deposition and a preparation process thereof. Background technique [0002] Affected by the environmental medium, a chemical or electrochemical multiphase reaction will occur on the interface of the metal material, causing the metal element to become oxidized or ionized, and the metal material will be damaged. This phenomenon is called metal corrosion. Corrosion will reduce the strength, plasticity, toughness and other mechanical properties of metal materials, and then affect the geometric shape and physical properties of components, parts, equipment, etc. made of metal materials, shorten the service life, and even cause safety accidents. Corrosion of metals is very common, among which the corrosion of iron products, the most used metal, is the most common. To deal with metal corrosion, one is to change ...
