Iron phosphate

Ọgwụgwọ na phosphate iron (nke a na-akpọkarị phosphating thin Layer) na-enye ezigbo ihe nrapado na enweghị mmetụta na-adịghị mma na njiri arụ ọrụ nke mkpuchi ntụ ntụ. Iron phosphate na-enye nchebe corrosion dị mma maka ikpughe na klas corrosion dị ala na nke etiti, n'agbanyeghị na ọ nweghị ike ịsọ mpi zinc phosphate na nke a. Enwere ike iji ígwè phosphate mee ihe n'ebe a na-efesa ma ọ bụ n'ime mmiri. Ọnụ ọgụgụ nke usoro na usoro nwere ike ịdị iche site na 2-7, dabere na basemetal na ihe achọrọ maka nchebe. N'ihe gbasara ọgwụgwọ zinc phosphate, usoro phosphate iron bụ mkpụrụ ndụ ihe nketaraldị ọnụ ala ma dị mfe iji rụzuo oyi akwa phosphate na-adịkarị n'etiti 0.3-1.0g/m2.

Zinc phosphate

Usoro zinc phosphate na-edobe akwa oyi akwa karịa ígwè phosphating, ma tinyekwa ya n'ime ihe ndabere. Zinc phosphate nwekwara nnọọ mma adhesion Njirimara, ọ bụ ezie na n'ọnọdụ ụfọdụ ọ nwere ike ibelata n'ibu iguzosi ike n'ezi ihe (mgbanwe nke usoro. Zinc phosphate na-enye magburu onwe corrosion nchebe na-akwadoro maka tupu ọgwụgwọ nke ígwè na galvanized ígwè maka ikpughe na elu corrosion klas. Enwere ike iji Zinc phosphate mee ihe na ebe a na-agba mmiri ma ọ bụ n'ime mmiri, ọnụ ọgụgụ nke usoro na-adịgasị iche n'etiti 4-8.
Zinc phosphating na-adịkarị ọnụ karịa iron phosphating, n'ihi ma ọnụ ahịa osisi dị elu yana ọrụ dị oke ọnụ.

Chromate

Usoro usoro dị iche iche dị n'ime otu chromate nke ọgwụgwọ. Usoro a họọrọ na-adabere n'ụdị ígwè ma ọ bụ alloy, ụdị ihe (usoro nke mmepụta: casr, extruded wdg) na n'ezie, àgwà chọrọ.
Enwere ike kewaa ọgwụgwọ chromate n'ime:

Nke ikpeazụ bụ usoro a na-ahụkarị maka ọgwụgwọ tupu tupu mkpuchi ntụ ntụ. Ọnụ ọgụgụ nke usoro na usoro ahụ nwere ike ịdị iche iche, dabere n'otú a ga-esi kwadebe ngwongwo maka chromating, dịka ọmụmaatụ site na pickling, neut.ralization wdg na n'ihi na nchacha nzọụkwụ.
