1.Dab tsi yog qhov kev ntsuas qhov tob ntawm khawb thiab lawv qhov cuam tshuam ncaj qha?
Cov Khaub Ncaws Me (Tshwj xeeb tsuas yog cov txheej oxide saum npoo los yog txheej ntiav heev)
Yam ntxwv: Pom pom ntawm qhov muag liab qab, tab sis NW nyuam qhuav hnov lossis hnov me ntsis thaum khawb nrog ib tug ntiv tes; Qhov tob feem ntau tsawg dua li ob peb micrometers.
Kev cuam tshuam: Feem ntau cuam tshuam rau qhov tsos. Tej zaum nws yuav tsis raug muab zais kiag li tom qab txau tom ntej los yog electroplating, uas ua rau cov cim ntawm cov khoom kawg. Nws zoo li tsis muaj kev cuam tshuam rau lub zog ntawm cov qauv lossis corrosion kuj.
Nruab Nrab Scratches (Muaj cuam tshuam rau lub substrate, nrog pom qhov tob thiab tactile tawm tswv yim)
Yam ntxwv: Pom pom ntawm qhov muag liab qab; hnov tsis kam thaum khawb nrog ib tug ntiv tes; Qhov tob yuav yog 10-50 micrometers lossis tob dua, tab sis tsis nkag mus rau lub ntsiab thickness.
Kev cuam tshuam:
Stress Concentration: Lub ntsej muag ntse nyob hauv qab ntawm qhov khawb ua ib qho kev ntxhov siab. Thaum khoov tom ntej, stamping, lossis load-cov kabmob, tawg lossis tawg tau yooj yim pib ntawm qhov no.
Txo Corrosion Resistance: cuam tshuam nto txuas ntxiv; Txawm tias tom qab galvanizing lossis txau, corrosive media tuaj yeem yooj yim sib sib zog nqus hauv qhov khawb, dhau los ua qhov pib ntawm corrosion, ua rau "linear corrosion" lossis kis ntawm xeb.
Txheej tsis xws luag: Xim lossis hmoov tsis tuaj yeem npog qhov khawb tob, uas tuaj yeem ua rau cov txheej txheem tsis sib xws thiab tev tawm ntxov.
Kev khawb hnyav (qhov tob txaus kom pom hauv qab lossis tshwm li grooves)
Yam ntxwv: Qhov tob yuav ncav cuag 0.1 hli lossis ntau dua, qee zaum nrog plowing lossis curling ntawm cov khoom.
Kev cuam tshuam:
Kev puas tsuaj ntawm cov qauv: Ncaj nraim txo cov khoom siv tau zoo -cov kabmob thickness ntawm cov khoom, txo nws lub zog thiab rigidity.
Moulding tsis ua haujlwm: Yuav luag 100% yuav tawg thaum cov txheej txheem molding tom ntej.
Kev ua haujlwm tsis zoo: Rau cov ntawv thov uas xav tau kev sib khi siab (xws li cov khoom siv plua plav) lossis cov khoom ua kom tiav (xws li cov menyuam muaj tseeb, siab- cov khoom siv kawg), qhov no ncaj qha ua rau muaj qhov tsis xws luag.
2.Yuav ntsuas li cas raws li kev siv kawg?
Cov yam ntxwv / zais cov khoom (piv txwv li, kev txhawb nqa sab hauv ntawm lub tsev cog khoom thav ntawv, kev txhawb nqa khoom siv sab hauv)
Qhov yuav tsum tau muaj: Lub zog yog qhov tseem ceeb, qhov tsos yog qhov thib ob.
Kev kam rau siab: kwv yees siab. Kev khawb sab saum toj yog feem ntau txais tau. Txawm li cas los xij, kev khawb me me mus rau qhov hnyav, tshwj xeeb tshaj yog nyob rau hauv qhov chaw khoov tom ntej lossis cov ntsiab lus tseem ceeb ntawm kev ntxhov siab, yog qhov tsis tsim nyog.
Cov tsos mob / Cov npog sab nrauv (xws li, cov khoom vaj tse, lub tsheb of elevator, tsheb sab nrauv vaj huam sib luag)
Qhov yuav tsum tau muaj: Nto zoo yog qhov taw qhia tseem ceeb.
Tolerance: Tsawg heev. Txhua qhov khawb pom ntawm qhov muag liab qab thiab palpable rau qhov kov yuav tshwm sim tom qab pleev xim thiab feem ntau suav hais tias tsis tuaj yeem lees txais.
Yam Yuav Tsum Tau Ua Tom Qab Sib Nrauj lossis Teeb Duab (xws li, cov khoom siv hauv tsheb, cov ntawv hlau nyuaj)
Qhov yuav tsum tau muaj: Cov khoom siv yuav tsum muaj kev txuas ntxiv zoo meej; tej yam tsis xws luag yuav tau amplified thaum tsim.
Tolerance: Tsawg heev. Txhua qhov khawb uas ua rau lub substrate puas muaj kev pheej hmoo siab - thiab tuaj yeem ua rau pwm puas lossis cov khoom tawg thiab khawb.
3.Dab tsi yog cov qauv kev lag luam thiab cov txheej txheem kuaj?
Cov Qauv: Feem ntau ua raws li cov qauv hauv tebchaws (xws li GB / T), cov qauv kev lag luam, lossis kev pom zoo ntawm tus neeg yuav khoom thiab tus muag khoom.
Txoj Kev Tshuaj Xyuas: Ntxiv nrog rau kev tshuaj xyuas qhov muag, ntau txoj hauv kev suav nrog ntiv tes kov, ntiv tes xoo ntiv tes, ntsuas qhov tob nrog lub teeb dawb / xiav interferometer, thiab kev txheeb xyuas seem metallographic.
Cov Kev Cai Lij Choj: Rau qib siab -qib txias- cov ntawv dov (xws li O5 nplooj ntawv, automotive txheej vaj huam sib luag), cov qauv yuav qhia tias "tsis muaj khawb los ntawm tes" lossis "kos qhov tob tsis tshaj X% (xws li 3-5%) ntawm cov ntawv hlau tuab."
4.Yuav ntsuas kev khawb li cas?
Qhov tob: Nws puas pom qhov kov? Nws puas tau puas lub substrate?
Puab: Puas yog ib kab, ntau kab, lossis tuab "hairline" qauv?
Qhov chaw: Puas yog nws nyob rau tom ntej shearing npoo, khoov kab, vuam qhov chaw, lossis qhov chaw raug?
5.Yuav ua li cas txiav txim siab?
Tsis lees txais / Scraped: Siv rau sab nrauv sab nrauv, sib sib zog nqus sib sib zog nqus, thiab siab corrosion kuj yuav tsum tau, qhov chaw khawb tob thiab tactile.
Conditionally Txais/Degraded: Siv rau cov uas tsis yog - tseem ceeb, tsis yog - sab nrauv structural Cheebtsam, qhov twg khawb me me thiab nyob deb ntawm lub machining cheeb tsam. Cov neeg siv khoom lossis tom ntej - theem kev pom zoo yuav tsum tau.
Kho: Rau qee qhov tsis yog - cov khoom tseem ceeb, khawb tuaj yeem raug tshem tawm los ntawm kev sib tsoo, polishing, thiab lwm yam, tab sis nws yuav tsum tau ua kom ntseeg tau tias cov khoom tuab thiab du nto tsis hloov pauv ntau.
