Phosphate conversion coating - Wikipedia

Phosphate coating is used on steel parts for corrosion resistance, lubrication, or as a foundation for subsequent coatings or painting. It serves as a conversion coating in which a dilute solution of phosphoric acid and phosphate salts is applied via spraying or immersion and chemically reacts with the surface of the part being coated to form a layer of insoluble, crystalline phosphates.

Substrate-level vs Oxidative Phosphorylation – DBriers.com

An example of substrate level phosphorylation that occurs in glycolysis is the production of ATP when 1,3 bisphophoglycerate is converted into 3-phosphoglycerate. The phosphate is removed directly from the substrate( 1,3 bisphophoglycerate) and joined with ADP to make ATP. This process can occur in conditions where no oxygen in present.
