Introduction of Corrosion Resistant Alloy Metal Spray Plating Process
阅读: 0 Posted by: 2014-1-9 16 : 52 : 42Read : 0 times

Metal spraying is the process of spraying molten corrosion-resistant alloy metal to the surface of the metal with compressed air or inert gas to maintain the coating. During metal spraying, the plating material is melted and atomized in a special spray or spray gun, and is sprayed onto the substrate material. This surface decoration method is sometimes called metal spraying. Oxygen-acetylene flames are usually used, but other gases are sometimes used. When the coated metal wire is actively fed by the flame center, the metal wire is melted and atomized by the condensed air stream and blasted onto the base material. Almost any metal that can be made into a wire can be sprayed in this way. Another type of spray gun uses powdered material to be emitted through a flame. The advantage of this method is that it can not only spray metal, but also cermet composite materials, oxides and cemented carbides.

Appearance preparation before spraying

Because the connection between the plating data obtained by metal spraying and the base material is a simple mechanical connection, it is necessary to perform proper pre-treatment of the base material. In order to obtain outstanding mechanical contacts. No matter what appearance preparation method is used, the external appearance of the substrate must be hygienic and free of oil.

The most common method of appearance preparation is sandblasting. For this reason, the sand grains meet the sharpness to produce a truly rough appearance. As for the cylindrical appearance that can be reversed on a lathe, it is useful to turn out very thick threads and then quietly roll the crest with a rolling knife. One improvement method that can be used for flat surfaces is to cut a series of parallel grooves with a circular groove cutter, and then use a knurling knife to grab the edges between the grooves. If the plating surface is to be processed, the substrate surface should be prepared by roughing or grooving to get the best preparation.

Use of metallization

Metal spraying has many important uses in product description. For example, zinc and aluminum can be spray coated onto the surface of steel to obtain a maintenance coating to obtain corrosion resistance. Because metal spraying can spray metal onto almost any metal or non-metallic appearance, it provides a simple way to coat a conductive surface on a poor or non-conductive surface. For this reason, copper is often used. Or silver sprayed on glass or plastic. Because the sprayed metal can be processed by various methods, such as polishing, brushing, or saving the spraying status, the sprayed metal can be used as a decoration method in the product and construction industry.
