Embodiment Construction

[0027] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0028] The plasma spraying process of the present embodiment comprises the following steps:

[0029] S1. Before spraying, place the sandblasted workpiece in the cleaning tank for cleaning, and use an air gun to dry the workpiece after cleaning. The purpose of cleaning is to effectively remove oil and other impurities on the surface of the workpiece, so that the subsequent sprayed coating will adhere more firmly and improve product quality. The specific cleaning method is: soak the workpiece in weak alkali solution at room temperature, and then take it out Rinse with pure water.

[0030] S2. Paste the spray tape on all the non-sprayed surfaces of the workpiece. It needs to be specially explained that the edge of the tape is 2mm away from the adjacent workpiece surface and the cut marks are neat. Use a scraper to scrape in the same directi...

Abstract

The invention discloses a plasma spraying technology. Coatings on boundary portions can be effectively prevented from falling off when adhesive tapes are demounted down from corners and sides of sprayed faces of a workpiece, and therefore the product quality is improved. By means of the small-area local high temperature of a spraying flame, the color difference on the surface of the workpiece is effectively removed, the problem of workpiece (especially workpiece made of a metal material) deformation caused by long-time drying box high-temperature heat treatment in traditional technologies is avoided, and the appearance uniformity of a finally-obtained product is good; and according to the technology, consumed time is short, a large quantity of time cost is saved, the production period is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a spraying process, in particular to a plasma spraying process. Background technique [0002] Plasma spraying is a material surface strengthening and surface modification technology, which can make the substrate surface have properties such as wear resistance, corrosion resistance, high temperature oxidation resistance, electrical insulation, heat insulation, radiation protection, wear reduction and sealing. Plasma spraying technology uses a plasma arc driven by direct current as a heat source to heat materials such as ceramics, alloys, and metals to a molten or semi-molten state, and sprays them on the surface of the pretreated workpiece at high speed to form a firmly adhered surface layer. [0003] Plasma spraying technology is widely used. When spraying polyhedral workpieces, it is necessary to pay attention to: not all surfaces are sprayed surfaces, and the sprayed surfaces need to be sprayed one by one to ensure the qualit...
