Phosphate conversion coating process
WebMay 26, 2015 · The phosphate process is the treatment of a metal surface that produces a reasonably hard, electrically non-conducting surface coating of insoluble phosphate that adheres to the underlying metal. It is used to enhance corrosion resistance, lubricity or as a foundation for subsequent coatings or paint. WebChromated and rinsed aluminium workpieces should be dried in driers or ovens but it is important not to set drying temperatures above 70°C. After all these treatment workpieces are painted then cured 10 – 15 minutes at 200°C for subsequent application of powder coating. Process line of chromate conversion coating can be set up as follows:
