Ukugqwala yisifo esibulalayo sentambo yensimbi, ikakhulukazi ezindaweni zasolwandle nasogwini. Emashumini eminyaka, i-Hot-Dipped Galvanization (HDG) iwukuphela kwekhambi. Nokho, ukuvela kwe-Zinc-Aluminium (Zn-Al) ingxubevange yengxubevange, njenge-Galfan, yethule ipharadigm entsha ekuvikelweni kwe-electrochemical.

I-Chemistry of Protection:

I-HDG yosiko incike kungqimba lomhlatshelo lwe-Zinc emsulwa. Uma lesi sendlalelo sesidliwe yi-oxidation, umgogodla wensimbi uyavezwa. I-Zn-Ama-Al alloys (imvamisa engu-95% Zn kanye no-5% Al) adala umgoqo oyinkimbinkimbi. Ukwengezwa kwe-Aluminium kudala 'ifilimu ye-passive' ye-aluminium oxide, elehlisa kakhulu izinga lokugqwala.

Ubufakazi Bokufutha Usawoti:

Ekuhlolweni okujwayelekile kwesifutho sikasawoti saselabhorethri (i-ASTM B117), i-Zn-Izintambo ezi-Al coated zihlala zidlula izintambo ze-HDG nge-factory of 2 kuya ku-3. Ngaphezu kwalokho, i-alloy coating idonsa kakhulu, okusho ukuthi imelana nokuvuleka{4}okuncane okwenzeka phakathi{5}}nomjikelezo wokucindezeleka ogoba ngaphezulu kwe-stress.

Isinqumo se-SOLITE:

Kuma-offshore mooring kanye nama-port cranes, ukushintshela ku-Zn-I-Al alloy coatings imele umnyakazo wokuvikela impahla. Nakuba iprimiyamu yezinto ezibonakalayo icishe ibe ngu-15%, ukunwetshwa kwempilo yesevisi okungu-200% kuyenza ibe ikhambi elibiza kakhulu-lokulwa{5}}ne-corrosion ku-metallurgy yesimanje. Sihlinzeka ngamadosi kasawoti abhalwe phansi{7}}kuzo zonke izimpahla zasolwandle-ezithunyelwayo.
