Umgaqo: Emva kokuba imathiriyeli ye-ferromagnetic kunye nezinto zokusebenza zenziwe umazibuthe, ngenxa yobukho bokungaqhubeki, imigca yemagnethi kumphezulu kunye kufuphi nomphezulu wezixhobo zokusebenza igqwetheka, okukhokelela ekuvuzeni kwemagnethi.Amasuntswana emagnethi asetyenziswa kumphezulu wezixhobo zokusebenza adsorbed, enza amanqaku abonakalayo omagnetic phantsi kokukhanya okufanelekileyo, ngaloo ndlela ebonisa indawo, imilo, kunye nobukhulu be-discontinuities.
Ukusebenza kunye nokunciphisa:
Ukuhlolwa kwamasuntswana emagnethi kukulungele ukubona ukungaqhubeki kumphezulu nakufutshane nomphezulu wemathiriyeli yeferromagnetic encinci kakhulu kwaye inezithuba ezimxinwa kakhulu (ezinje ngeentanda ezinokubonwa kubude be-0.1mm kunye nobubanzi beemicrometers) ekunzima ukuzibhaqa. ngokubonakalayo;Iyakwazi nokuhlola imathiriyeli ekrwada, iimveliso ezigqityiweyo, izixhobo zokusebenza ezigqityiweyo, kunye namalungu akwinkonzo, kunye neepleyiti, iiprofayili, imibhobho, imivalo, iindawo ezidityanisiweyo, iinxalenye zentsimbi ekhandiweyo, kunye neentsimbi ezikhandiweyo.Iziphene ezifana nokuqhekeka, ukufakwa, iinwele, amabala amhlophe, ukugoba, ukuvala okubandayo, kunye nokukhululeka kunokufumaneka.
Nangona kunjalo, uvavanyo lwamasuntswana amagnetic alukwazi ukubona izixhobo zentsimbi engenakutyiwa nge-austenitic kunye ne-welds ezidityaniswe nge-electrode yensimbi engenasici ye-austenitic, kwaye ayinakukwazi ukubona imathiriyeli engeyiyo kazibuthe efana nobhedu, i-aluminium, i-magnesium, i-titanium, njl njl. , kunye ne-delamination kunye nokusonga nge-engile engaphantsi kwe-20 ° ukusuka kumphezulu womsebenzi.
Uvavanyo olungeneyo (PT)
Umgaqo: Emva kokuba umphezulu wenxalenye uhlanganiswe ne-penetrant equkethe i-fluorescent okanye i-coloring dyes, phantsi kwesenzo sombhobho we-capillary, emva kwexesha elithile, i-penetrant ingangena kwiiphene zokuvula umphezulu;Emva kokususa i-penetrant engaphezulu phezu kwendawo, umphuhlisi usetyenziswa kumphezulu wenxalenye.Ngokufanayo, phantsi kwesenzo se-capillary, umthuthukisi uya kutsala i-penetrant egciniweyo kwi-defect, kwaye i-penetrant iya kuphinda ibuyele kumthuthukisi.Ngaphantsi komthombo othile wokukhanya (i-ultraviolet okanye ukukhanya okumhlophe), ukulandelwa kwe-penetrant kwi-defect kuyenzeka (i-fluorescence eluhlaza okwesibhakabhaka okanye ebomvu eqaqambileyo), ngaloo ndlela ibona i-morphology kunye nesimo sokusabalalisa kwesiphene.
Izinto eziluncedo kunye nemida:
Uvavanyo olungena ngaphakathi lunokubona izinto ezahlukeneyo, kubandakanya nentsimbi kunye nezinto ezingezizo ezentsimbi;Izixhobo zemagneti nezingezizo;Welding, forging, rolling kunye nezinye iindlela zokulungisa;Inovakalelo oluphezulu (inokufumaneka ukuba yi-0.1 μ M i-defect ebanzi, kunye nomboniso ocacileyo, ukusebenza kakuhle, kunye nexabiso eliphantsi lokufumanisa.
Kodwa inokubona kuphela iziphene ngokuvuleka komphezulu kwaye ayifanelekanga ukuhlola izixhobo zokusebenza ezenziwe ngezinto ezinqabileyo kunye nezikhululekile kunye neendawo zokusebenza ezinemigangatho erhabaxa;Ukwabiwa komphezulu kuphela kweziphene kunokubonwa, okwenza kube nzima ukumisela ubunzulu bokwenene beziphene, okwenza kube nzima ukuvavanya ubungakanani beziphoso.Iziphumo zokubhaqwa zikwaphenjelelwa kakhulu ngumsebenzisi.
