Embodiment 1

[0020] A plasma coating surface treatment method, the specific treatment steps are as follows:

[0021] Step 1: Preliminary cleaning of the parts to be coated with plasma coating, and rough grinding of the surface.

[0022] Step 2: Degreasing the polished parts to be coated in Step 1 with a degreasing agent, followed by decontamination, water rinsing, deionized water rinsing and dehydration drying.

[0023] Step 3: Send alumina, steel, copper, titanium, chromium, and tungsten into the jet mill for grinding, and add a reducing agent during the grinding process. After grinding, use a bag filter to collect to obtain metal powder.

[0024] Step 4: Send the metal powder obtained in Step 3 to the plasma coater, place the parts to be coated in Step 2 on the plating table, and use the ion coater to perform high-temperature plating on them.

Abstract

The invention discloses a plasma coating surface treatment method. The plasma coating surface treatment method comprises the following steps: I, initially cleaning a plasma coating part needing to becoated, and roughly grinding the surface of the plasma coating part; II, removing oil from the part to be coated which is ground in the step I through an oil remover, and performing decontamination, water washing, deionized water washing and dehydration-drying in sequence; III, introducing aluminum oxide, steel, copper, titanium, chromium and tungsten into an airflow mill for grinding, adding a reducing agent in the grinding process, and collecting with a bag collector at the end of grinding to obtain metal powder; IV, conveying the metal powder obtained in the step III into a plasma coating device, placing the part to be coated which is treated in the step II on a coating table, and performing high-temperature coating on the part to be coated with the plasma coating device. The surface ofthe cooled metal coated part is subjected to hole-sealing treatment by using silicon dioxide sol, so that the corrosion resistance and oxidation resistance of the surface of the metal coated part areimproved effectively.

Description

technical field [0001] The invention belongs to the technical field of coating processing, and in particular relates to a plasma coating surface treatment method. Background technique [0002] After the coated parts are coated and cooled, tiny pores will be formed due to thermal expansion and contraction. During use, the corrosive medium will penetrate into the substrate through these micropores, causing corrosion and greatly reducing the service life of the coating. Cracks, shedding, etc. occur, reducing the service life of the coated parts. Contents of the invention [0003] The object of the present invention is to provide a kind of plasma coating surface treatment method, to solve the above-mentioned background technology proposed in the above-mentioned background technology after coating cooling, can form tiny hole because of the reason of thermal expansion and contraction, in use process, The corrosive medium will penetrate into the substrate through these micropore...
