1. Pom kev tshuaj xyuas
GLAG hloov: Yog tias lub Chrome Deg ua Hazened, Matte, lossis ib nrab tsaus ntuj (piv txwv li, los ntawm daim duab {} zoo li ua kom tiav), ntawm cov yeeb yaj kiab oxide yog puas.
Xeb thiab corrosion: pom reddish - xim av xeb me ntsis ntawm cov tsheb ntug hiav txwv (piv txwv li, yuav tsum tau ua raws li peb xyoos) yuav tsum tau saib xyuas tam sim ntawd.
Plating Peeting: Yog tias lub plating nqa lossis peels (thaj chaw> 1 cm²) ntawm cov npoo lossis cov hauv paus, cov khoom siv tau tshwm sim thiab yuav tsum tau kho cov kev tshaj lij.
2. Kev soj ntsuam lub cev puas
Kos qhov tob: me me kos cov kos nrog koj cov rau tes. Yog tias nws pom tau tias pom tseeb indented (tob> 0.1 hli), cov khoom tiv thaiv ntawm lub plating tau cog tseg.
Microcack tsis ntev: Saib xyuas qhov chaw ua kom tawg nrog lub khob loj dua. Yog tias cov ntom ntom ntom nti
Decreased Wear Resistance: Obvious signs of wear (e.g., grooves >0.5mm dav) tshwm sim hauv cov cheeb tsam kom nquag sib txhuam (piv txwv li, piston pas nrig) qhia tias tsis muaj txiaj ntsig plating hardness.
Kev ua raws li kev ua haujlwm txawv: Siv cov kev ntsuas ntau kom ntsuas tsis kam. Yog hais tias tus nqi tiv taus ntau dua 20% siab dua thaum tshiab, corrosion tej zaum tau ua rau cov txheej txheem customive.
4. Ib puag ncig thiab lub neej
Cov pob zeb tsim hluav taws xob ib puag ncig: Chrome plating cov nroj tsuag thiab cov chaw ntug dej hiav txwv uas pom zoo kom raug tshuaj xyuas txhua peb lub hlis.
Ib puag ncig ib puag ncig: Chrome plating pas rau cov khoom siv kev lag luam yuav tsum tau tshuaj xyuas txhua rau lub hlis, thiab ntu trim tsheb yuav tsum tau kuaj xyuas ib xyoos ib zaug.
5. Kev Tshawb Fawb Kev Ntsuas
Thickness ntsuas: Siv cov electrolytic cov cuab yeej ntsuas ntsuas kom ntsuas cov plating thickness. Yog hais tias lub thickness yog tsawg dua 50% ntawm thawj tus nqi (piv txwv li, 10μm seem ntawm 20μm txheej), rov} plating yuav tsum tau.
Ntsev txau mus kuaj: kuaj hauv lub sim sim 5% sodium chloride ib puag ncig. Qhov kev sim ntsuas ntawm 168 teev ntawm xeb {{3} Kev ua tau dawb} dawb tau txais; Txwv tsis pub, kev txij nkawm yog qhov yuav tsum tau ua.
