What Is The Zinc Phosphate Coating Ask The Professional
If you want to improve corrosion protection beyond what you would normally get with stainless steel, you can use displacement or water-soluble oil for that. Zinc phosphates are also used for anti-galling purposes to change the friction of the mesh parts. Decorative applications are more for aesthetic appeal or for the presentation of the piece at the point of sale.
The thermal desorption spectra for Zinc Phosphate coated samples thermally immersed in PAO / ester, with or without the black oxide layer removed during ADD. The sample thermal desorption spectra covered with Zinc Phosphate without thermal immersion with the coating removed before ADD was included in the figure for comparison. A significant amount of hydrogen was detected if the oxide layer during ADD is not removed after thermal immersion in PAO / ester. Minimal hydrogen is detected after thermal immersion when the oxide layer is removed before ADD. With the oxide layer removed during ADD, the hydrogen detected in the black oxide-coated sample without thermal immersion is greater than that experienced by thermal immersion. The Zinc Phosphate process is alkaline in nature and supports ferrous metals, tool steel, and powdered metals.
