Darasi na 8.8 Black Oxide Hex Socket Head Cap Screws-Bayyanawar Fasaha na Kariyar Lalacewa da Ƙirar Kai 

2. Grade 8.8 Black Oxide Gama: Kariyar Lalacewa

2.1 Menene Black Oxide?

Black oxide, wanda kuma ake magana da shi a matsayin baƙar fata, wani shafi ne na jujjuya sinadarai da aka samar ta hanyar mayar da martanin saman ƙarfe na ƙarfe tare da maganin alkaline oxidizing a yanayin zafi mai tsayi (yawanci 140 zuwa 150 digiri Celsius). Ba kamar kayan kwalliyar lantarki irin su zinc ko Dacromet, waɗanda ke ajiye wani nau'in ƙarfe daban-daban a saman ma'auni, baƙin ƙarfe oxide yana jujjuya mafi girman Layer na ƙarfe da kansa zuwa magnetite (Fe3O4), oxide baƙin ƙarfe mai tsayi. Sakamako shine bakin bakin ciki, matte-baƙi saman wanda ya zama wani ɓangare na maɗauri maimakon ƙara-kan Layer.

2.2 Tsarin Black Oxide

Daidaitaccen tsari na baƙin ƙarfe oxide don masu ɗaure Grade 8.8 ya ƙunshi matakai masu zuwa:

Ragewa da tsabtace alkaline don cire mai, yanke ruwa, da gurɓataccen shago.

Cire acid don cire duk wani sikelin saman ko tsatsa mai haske.

Nitsewa a cikin wanka mai zafi na alkaline-oxidizing (kimanin digiri 141 ma'aunin celcius), inda Layer magnetite ke samuwa a cikin mintuna 10 zuwa 20.
