The detection of phosphate in a coating shall be taken as proof that it is a phosphate coating cf.

If necessary, scrub the coating off with a rubber wiper. Learn more about the cookies we use and how to change your settings. Use the other half of the solution to test for the presence di calcium as described in subclause NA.

Zinc phosphate coatings should be neutralized after rinsing, by treatment with a weakly alkaline aqueous solution.

The phosphate layers improved corrosion protection and the coating adhesion, and favorable anti-friction properties can be achieved by incorporating lubricants in the microporous surface.

Review of gravimetric and chemical analysis methods Status: Previous editions DIN Dn der flaechenbezogenen Masse. To identify the purified white precipitate as calcium oxalate, remove it from the filter by spraying with hot distilled water, and then add about 50 ml of distilled water.

Review of gravimetric and chemical analysis methods.

A white precipitate, which may have a slight green tinge due to the presence of a small amount of iron, indicates the presence of zinc. Iron din alkali phosphating is used vin example for deep drawn parts.

Summarizes recommendations for phosphate conversion coatings Zinc phosphate coatings to ensure good adhesion of paints, dinsimilar coating materials, sealants, PTFE, wax, grease or oil. In phosphate bonderizinga property-enhancing conversion layer is applied dun chemically altering the surface.

The rin colour varies from light to dark grey depending on the composition of the material and its surface mechanical working and any previous thermal treatment. Soap lubrication can be performed by dipping in a suitable soap solution tube drawing, cold heading, cold extrusion, deep drawing. In phosphate bonderizinga property-enhancing conversion layer is applied by chemically altering the surface.

In addition din corrosion resistance, the phosphating can fulfil an extremely useful role for anchoring other applied materials like rubber, Teflon, stearate, laccar, paint, etc.

Manganese phosphating is therefore preferred for friction bearings, intake bushes and dih applications that are subject to din loads.
