WebDec 8, 2024 · Laser phosphate removal, also known as laser coating removal, is the process of removing coatings using the heat of a laser beam. As the coating is heated, it is vaporized into dust and fumes that must be extracted with a proper fume extractor. The laser beam can also be configured to strip coatings from localized areas with extreme precision. WebThe zinc phosphate continues to be the main coating constituent. The addition of nickel and manganese promotes grain refinement and enhances the corrosion resistance of the phosphate layer. This type of coating is known as trication phosphate. The thickness of zinc-phosphate coatings varies from 1 to 43 g/m 2, most frequently from 1 to 20 g/m 2.
