ИСО 9717-2017 Phosphate conversion films for metalsMethod for determining requirements

А Префаце
ИСО (Међународна организација за стандардизацију) је глобални савез националних тела за стандардизацију (Тела чланица ИСО). Развој међународних стандарда се обично спроводи преко ИСО техничких комитета. Свака институција чланица заинтересована за предмет за који је основан технички комитет има право да буде заступљена у комитету. У овај посао су укључене и владине и невладине међународне организације које су у вези са организацијама за стандардизацију. ИСО блиско сарађује са Међународном електротехничком комисијом (ИЕЦ) о свим питањима електричне стандардизације.

The procedures used to develop this document as well as those used for further maintenance are described in Part 1 ИСО/ИЕЦ директиве. Нарочито, треба обратити пажњу на различите критеријуме одобрења који су потребни за различите типове ИСО докумената. Овај документ је састављен у складу са уређивачким правилима Дел 2 ИСО/ИЕЦ директиве (види исо.орг/дирецтивес).

Увод
Phosphate conversion coatings are applied to ferrous metals, алуминијум, zinc and their alloys (including galvanized and zinc-alloyed steel, cadmium and their alloys) as end faces or as interlayers for other coatings. They are designed to

Imparts corrosion resistance,

Improves adhesion to paints and other organic finishes,

promote cold forming operation, such as drawing, tubing, and extrusion, as well

Modification of surface friction properties to facilitate sliding.

Phosphate conversion coating is produced by solution treatment, its main composition is proper orthophosphoric acid dihydrogen salt. These coatings are mainly applied to ferrous materials and zinc, and the coating quality and apparent density per unit area vary depending on

component of building materials and surface condition,

prior to mechanical and chemical processing of parts, as well

phosphating treatment conditions.

More or less all phosphate conversion coating is porous, but can be by subsequent sealant for which the material sealing process.
