    If you want to remove chemicals during the phosphate coating removal process, laser cleaning machine may be the solution you are looking for. This up-and-coming finish has found its place in many production lines looking to simplify the manufacturing process and reduce costs.


    Removal of Phosphate Coatings Using Laser Cleaning Phosphating processes using phosphoric acid are hazardous and include steps such as degreasing, phosphate baths, post-phosphating water rinses, chromic acid rinses, and wastewater treatment.


    If you've ever stripped a phosphate coating from a part, or managed a phosphate conversion coating process, chances are you've seen quite a few chemicals. Traditional phosphate removal methods rely on chemical strippers such as hydrochloric acid and sulfuric acid. Other strongly alkaline and chelating solutions are equally dangerous.

What is Laser Phosphorus Removal?


    Laser phosphorus removal, also known as laser coating removal, is the process of removing coatings using the heat of a laser beam. When the coating is heated, it evaporates into dust and fumes, which must be extracted using a suitable fume extractor.


    The laser beam can also be configured to strip coatings from localized areas with extreme precision. One of the most revolutionary applications is replacement part masking: after coating the entire part, simply remove the coating from an area. Surface preparation before welding is another important application.


    The process leaves the metal substrate unharmed. The high temperature of the beam is sufficient to ablate the coating, but not the metal. Laser ablation can be used to clean any type of metal part, including stainless steel. If you want to learn more about this reaction, read our article on how laser cleaning works.


    Industrial laser cleaning can remove all types of phosphate coatings, including iron phosphate coatings, manganese phosphate coatings, and zinc phosphate coatings. It does not require secondary treatment as it also removes any contaminants that may have mixed with the protective coating, including oils and oxides.
