63. Cov ntsiab lus nickel hauv cov kav hlau thiab cov lauj kaub galvanized substrates cuam tshuam li cas rau kub-dip galvanizing?

Nickel (Ni), cov hlau grey nrog lub cubic lossis hexagonal siv lead ua qauv, muaj cov txheeb ze atomic loj ntawm 58.69, melting point ntawm 1455 degree, thiab boiling point ntawm kwv yees li 2340 degree. Hais txog nws qhov cuam tshuam rau kub -dip galvanizing, sib txawv ntawm kev sim ntawm cov kws tshawb fawb tau ua rau muaj kev tsis sib haum xeeb. Piv txwv li, kev sib piv ntawm cov nickel-dawb qis- carbon steel thiab 5% nickel- muaj cov pa roj carbon tsawg - carbon steel ntawm 460℃zinc da dej kub pom tau tias 30% txo qhov corrosion rau tom kawg. Thaum cov ntsiab lus npib tsib xee nce mus txog 8%, galvanized txheej thickness txo qis, qhia tias cov nickel element tswj kev txhim kho ntawm ζ theem.
