201994 Parkerizing, bonderizing, phosphating, or phosphatizing is a method of protecting a steel surface from corrosion and increasing its resistance to wear through the application of a chemical phosphate conversion coating. Parkerizing is usually considered to be an improved zinc or manganese phosphating process, and not to be an improved iron
phosphate. This step can be omitted for iron phosphate process. 6. Phosphating This forms coating of zinc phosphate 4 to 6 microns.

2012423 Manganese phosphate coating process is generally used for the coating of metal parts that work under oily environment. It prevents galling and provides excellent wear protection on iron and steel. Oil treatment is commonly employed as post treatment. Manganese phosphating is mostly used in automotive and defence industries.
Manganese phosphate coatings are used for reducing wear and for improvement in the running-in of a gearbox. In the phosphating process, phosphoric acid pickles the suface and forms with Mn-ions a.
Phosphating is a process that is used to coat metals, such as iron and steel. In this process, a phosphate of another type of metal, such as zinc, is coated onto a piece of iron or steel to protect it from corrosion. By phosphating a piece of metal, the metal is protected from rust and prepared for other treatment processes, like painting.

Phosphating. Phosphating is the treatment of metallic surfaces with aqueous and acid phosphatecontaining solutions. The metal phosphate conversion layer resulting from the chemical reaction is slightly soluble and adheres firmly to the substrate. Phosphating
Phosphating metal surfaces with zinc or iron phosphate easily in a multistage metal pretreatment system for powder, paint, Ecoat and plating operations.
2017827 phosphating process was felt way back in the 19th century and its development has gained rapid momentum with the advent of the Bonderite process in 1929. Recently, Sankara Narayanan et al 17 have made an overview on the acceleration of the phosphating process and justified its role to reduce process time.
1987120 The present invention relates to a process for phosphating metals, in particular steel and galvanized steel, by a spray method, using an aqueous acidic phosphating solution containing an accelerator, zinc and, if appropriate, nickel, and the use of this process prior to electrocoating.
2012-3-18 · Manganese phosphating as a wear protection measure is widely used in the auto industry. Gearwheels in the gearbox, crown and pinion gears in the differential, cam-shafts, valves and valve-steams as well as pistons in larger diesel engines are frequently treated in this way.
Phosphating requires use of iron or zinc salts depending on the materials intended use and final corrosion resistance desired. It is a process that can be applied by spraying or by immersion, depending on the shape and structure of the part.
Phosphating is the process of converting a steel surface to iron phosphate. This is mostly used as a pretreatment method in conjunction with another method of corrosion protection.
