Zr702 Zirconium Bar Khoom Description
Zirconium 702 fasteners (ASTM B493), tseem hu ua UNS R60702, yog cov hlau reactive uas muaj kev sib raug zoo rau cov pa oxygen thiab tsim cov txheej tiv thaiv oxide hauv huab cua ntawm chav tsev kub. Cov oxide tiv thaiv txheej muab zirconium alloys universal corrosion kuj.
Cov txheej txheem oxide no tuaj yeem txhim kho los ntawm cov txheej txheem kho cua sov. Cov txheej txheem zoo li qub, txhim kho oxide txheej ua haujlwm zoo tshaj plaws ntawm cov kabmob, tiv taus ntau yam ntaub ntawv, tiv taus cov decomposition hauv high-speed thav duab, thiab txhim kho corrosion kuj nyob rau hauv tej qhov chaw corrosive.
Thaum Astm B493 zirconium 702 fasteners raug rau hydrochloric acid, tus nqi corrosion yog tsawg dua 5 mpy. Qhov no tsis tshua muaj corrosion kuj siv tau txawm tias thaum zirconium hexagon socket lub taub hau hau hau screws raug rau ntau yam ntawm cov concentrations ntawm hydrochloric acid los yog HCl, thiab mus rau ib tug ntau yam ntawm kub saum toj no lub boiling point.
