Phosphating is a popular and relatively simple process that has been used to protect metal from corrosion for more than 100 years. de Bussy was the first to obtain a British patent in 1864 for the treatment of iron with a mixture of coal-dust and calcium dihydrogen phosphate. In 1906 T.W. Coslett of Birmingham improved the process by adding zinc dihydrogen phosphate to the phosphoric acid and thereby became the originator of a process that is still in use today.
Phosphate coatings are used to provide a receptive surface for bonding fabric, wood and other material to steel, however the main application is as a foundation for paint.
The three most commonly used phosphates today are: · manganese phosphate · iron phosphate · zinc phosphate
