Abstract

The invention discloses a solvent-type tungsten carbide cobalt wear-resistant coating. The following components are calculated in parts by weight. The preparation method comprises the following steps: (1) weighing 40-60 parts of tungsten carbide cobalt powder, drying to remove crystal water, Obtain dry tungsten carbide cobalt powder; weigh 20-30 parts of epoxy resin, 1 part of silane coupling agent, 20-30 parts of ethanol and 3-7 parts of benzyl alcohol, mix and ultrasonically stir to obtain epoxy resin mixture liquid; add the dry tungsten carbide cobalt powder into the epoxy resin mixture, ultrasonically and stir evenly to obtain component A; (2) weigh 20-30 parts of polyamide, 7-13 parts of benzyl alcohol and 0.7 parts of graphene ‑1.3 parts, after mixing, ultrasonically and stir evenly to obtain component B; (3) Mix component A and component B, and stir evenly to obtain tungsten carbide cobalt wear-resistant coating. This solvent-based tungsten carbide cobalt wear-resistant coating does not require thermal spraying, which greatly saves the cost of spraying.

Description

technical field [0001] The invention relates to a solvent-type tungsten carbide cobalt wear-resistant coating. Background technique [0002] With the development of coating technology, coating the device surface has become an effective method for wear and corrosion protection. The process of coating the device surface protection is simple. Generally, it is only necessary to evenly apply the prepared wear-resistant coating to the parts to be protected. In recent years, the use of adhesive film coating technology to form a film on the surface of metal materials such as steel for protection has been widely studied. The composite formed by the adhesive film coating and metal makes the metal material more excellent performance; at the same time, due to The film is covered on the metal surface, which makes it have better corrosion resistance and wear resistance than metal, and can provide good wear and corrosion protection for mechanical parts in complex environments. However, w...
