1. Ci ci chrome: ci zoo li daim iav; 2. Sub-chrome: matt; 3. Electrophoresis: dub nciab, muaj qhov ci ntsa iab, nyob hauv qhov kev txiav txim sab nraud DC, cov nqi uas tau txav mus rau hauv kev coj ua ntawm cov dej nruab nrab mus rau cathode lossis anode los txhawb kev sib cais ntawm cov khoom; Phosphating: dub, tab sis qhov ci ntsa iab tsaus, cov khoom yog raus rau hauv cov kua phosphating, thiab tso rau saum npoo tsim ib txheej ntawm dej-insoluble crystalline phosphorus, uas yog txheej txheem ntawm hydrochloric acid conversion. 5. Grey Nickel: Nws yog ib qho chaw tshiab kev kho cov tshuaj kho nrog txoj kev muaj zog tiv thaiv xeb thiab yuav ua rau lub neej muaj kev pab cuam ntawm lub khoom. 6. Lwm tus yog xim dub, xauv npoo npauj npaim, xim ncoo, xim dub nciab thiab titanium plating.
Kev ntsuam xyuas cov cai
1. Tsis muaj xeb, burrs, tawg thiab me ntsis; 2. Tus pas nrig yog symmetrical, thiab lub laser ntawv yuav tsum paub meej; 3. Lub hardness yuav tsum ua tau raws li cov qauv qhia ntawv, thiab qhov chaw yuav tsum yog qhov tseeb. Lub cav hlau ntawm txoj hlua yuav hloov tau yooj yim thiab tus pin yuav tsum tsis txhob xoob.
