Firearms History, Technology & Development: Metal

2020-05-26· The process of applying a phosphate coating was originally invented in the 1850s, but really became prominent in the 1900s, thanks to improvements done by the Parker Rust-proof Phosphating Company in the 1915-1945 period, who were responsible for making it possible to mass produce parts using this metal treatment process.

Manganese phosphating for increased contact fatigue

2019-03-22· The FFI-project “Manganese phosphating for increased contact fatigue” was executed in cooperation between Scania, Swerea IVF AB and Swerea KIMAB AB. The main objective of the project was to increase the knowledge of the manganese phosphating process and its influence on the contact fatigue strength. This included the development

ELECTROCHEMICAL PHOSPHATE CONVERSION COATING:

Passivation (chemistry) Wikipedia

2020-06-11· Passivation, in physical chemistry and engineering, refers to a material becoming "passive," that is, less affected or corroded by the environment of future use. Passivation involves creation of an outer layer of shield material that is applied as a microcoating, created by chemical reaction with the base material, or allowed to build from spontaneous oxidation in the air.

EP0264811A1 Process for producing phosphate

Phosphate coatings are produced on surfaces of cold-rolled steel or steel galvanised on one or both sides by using, to produce coatings rich in phosphophyllite, a phosphating solution which contains 10 to 20 g/l of phosphate (calculated as PO4) 1.5 to 2.5 g/l of zinc (calculated as Zn) 5 to 15 g/l of nitrate (calculated as NO3) 0.5 to 1.5 g/l of fluoride (calculated as F) 0.5 to 1.5 g/l of
