Properties and Benefits of Phosphate Coatings
Corrosion Protection
Phosphate, followed by an appropriate post-treatment, provides added corrosion protection to the surface of the metal, prolonging service and increasing the shelf-life of stored parts.Anti-Galling
The phosphate finish provides an anti-galling surface for mating parts that sacrifices the lubricating layer of phosphate during initial contact and abrasion, while a work-hardened surface is being formed.Lubricity
The oil-based post-treatment available for phosphate not only provides added protection against corrosion, but also produces a lubricating film for smoother running of mating parts.Reduced Light Glare
The phosphate finish also reduces glare and eye fatigue in optical applications or where bright light reflection is a concern.Surface Preparation
The phosphate finish improves adhesion of parts prior to painting and lacquering processes.Economical
Phosphate is a simple, cost effective means of providing mild corrosion protection and increasing the aesthetic value of parts. It is a much faster process that saves time and money over painting or other metal finishing processes.
