Chromium hmoovKev piav qhia
Chromium yog hlau-grey, lustrous, thiab tawv hlau uas pom dav siv los ua catalyst lossis alloys. Tag nrho cov chromium tebchaw muaj khaus thiab ntau xim.
Chromium yog siv los ua hardener hauv cov hlau, rau kev tsim cov hlau tsis muaj steel thiab ntau cov alloys muaj txiaj ntsig. Nws kuj yog ua hauj lwm los muab iav emerald ntsuab xim. Chromium tsis oxidize nyob rau hauv huab cua, txawm nyob rau hauv huab cua noo.
Chromium hlau sai sai dhau los ua ib qho khoom tseem ceeb hauv ntau yam khoom siv vim nws cov yam ntxwv tshwj xeeb. Piv txwv ntawm cov ntawv thov no suav nrog stainless hlau, super alloys, aluminium alloys, thiab electronics. Cov qib siab stainless hlau, ua tau los ntawm kev ntxiv cov hlau chromium, yog qhov tseem ceeb rau kev ua haujlwm zoo thiab ib puag ncig zoo ntawm cov nroj tsuag tshuaj, cov chaw tsim hluav taws xob nuclear, kev ua zaub mov, thiab lwm yam kev lag luam tseem ceeb. Chromium hlau kuj yog ib qho tseem ceeb muaj nyob rau hauv ntau hom super alloys uas yog ib qho tseem ceeb rau lub aerospace thiab nuclear fais fab kev lag luam. Tsis ntev los no, chromium hlau ion plating tau dhau los ua ib puag ncig zoo rau lwm txoj hauv kev chromium plating.
