Lub hauv paus ntsiab lus: Tom qab cov ntaub ntawv ferromagnetic thiab workpieces yog magnetized, vim muaj cov discontinuities, cov magnetic teb kab nyob rau ntawm qhov chaw thiab nyob ze ntawm lub workpieces undergo lub zos distortion, uas ua rau kom cov magnetic teb. Cov khoom sib nqus siv rau saum npoo ntawm cov khoom ua haujlwm yog adsorbed, tsim cov cim sib nqus pom hauv qab teeb pom kev zoo, yog li nthuav tawm qhov chaw, duab, thiab qhov loj ntawm qhov tsis sib xws.
Kev siv thiab kev txwv:
Kev tshuaj xyuas cov khoom sib nqus yog tsim nyog rau kev kuaj xyuas qhov tsis sib xws ntawm qhov chaw thiab nyob ze ntawm cov ntaub ntawv ferromagnetic uas muaj me me thiab muaj qhov tsis tshua muaj nqaim (xws li cov kab nrib pleb uas tuaj yeem tshawb pom qhov ntev ntawm 0.1mm thiab dav ntawm micrometers) uas nyuaj rau kev kuaj xyuas pom kev; Nws tseem tuaj yeem tshawb xyuas cov khoom siv raw, cov khoom lag luam ib nrab, cov khoom ua tiav, thiab cov khoom siv hauv kev pabcuam, nrog rau cov phaj, profiles, kav, tuav, welded qhov chaw, cam khwb cia hlau qhov chaw, thiab forged steel qhov chaw. Cov kab mob xws li cov kab nrib pleb, suav nrog, cov kab plaub hau, cov pob dawb, folds, txias kaw, thiab xoob tuaj yeem pom.
Txawm li cas los xij, kev ntsuam xyuas cov khoom sib nqus tsis tuaj yeem ntes cov khoom siv austenitic stainless hlau thiab welds welded nrog austenitic stainless hlau electrodes, thiab nws tsis tuaj yeem ntes cov khoom tsis sib nqus xws li tooj liab, txhuas, magnesium, titanium, thiab lwm yam. , thiab delamination thiab folding nrog lub kaum sab xis tsawg dua 20 ° los ntawm qhov chaw ua haujlwm.
Kev Ntsuas Penetrant (PT)
Lub hauv paus ntsiab lus: Tom qab lub npoo ntawm ib feem yog coated nrog ib tug penetrant muaj fluorescent los yog xim dyes, nyob rau hauv qhov kev txiav txim ntawm ib tug capillary raj, tom qab ib tug lub sij hawm ntawm lub sij hawm, lub penetrant tuaj yeem nkag mus rau hauv qhov chaw qhib qhov tsis xws luag; Tom qab tshem tawm qhov dhau ntawm qhov nkag mus rau ntawm qhov chaw, tus tsim tawm yog siv rau qhov chaw ntawm qhov chaw. Ib yam li ntawd, nyob rau hauv qhov kev txiav txim ntawm ib tug capillary, tus tsim tawm yuav nyiam cov penetrant nyob rau hauv qhov tsis xws luag, thiab cov penetrant yuav nkag mus rau hauv tus tsim tawm. Nyob rau hauv ib lub teeb ci (ultraviolet los yog lub teeb dawb), cov cim ntawm qhov nkag mus ntawm qhov tsis xws luag (daj ntsuab fluorescence lossis ci liab), yog li kuaj pom cov morphology thiab kev faib tawm ntawm qhov tsis xws luag.
Qhov zoo thiab kev txwv:
Kev ntsuam xyuas Penetrant tuaj yeem ntes ntau yam khoom siv, suav nrog cov khoom siv hlau thiab cov khoom tsis yog xim hlau; Cov khoom siv sib nqus thiab tsis sib nqus; Vuam, forging, dov thiab lwm txoj kev ua; Muaj qhov rhiab heev (tuaj yeem pom tias yog 0.1 μ M dav qhov tsis xws luag, nrog cov khoom siv nkag siab, kev ua haujlwm yooj yim, thiab tus nqi qis dua.
Tab sis nws tsuas tuaj yeem txheeb xyuas qhov tsis xws luag nrog qhov qhib qhov chaw thiab tsis haum rau kev tshuaj xyuas cov khoom ua haujlwm ntawm cov khoom ntxeem tau thiab xoob thiab cov khoom ua haujlwm nrog cov khoom ntxhib; Tsuas yog qhov kev faib tawm ntawm qhov tsis xws luag tuaj yeem kuaj pom, ua rau nws nyuaj rau kev txiav txim siab qhov tob ntawm qhov tsis xws luag, ua rau nws nyuaj rau kev ntsuas qhov tsis xws. Cov txiaj ntsig kev tshawb nrhiav kuj tseem cuam tshuam los ntawm tus neeg teb xov tooj.
