Molao-motheo: Kamora hore lisebelisoa tsa ferromagnetic le li-workpiece li hoketsoe, ka lebaka la ho ba teng ha li-discontinuities, melapo ea matla a khoheli e holim'a metsi le haufi le bokaholimo ba lisebelisoa tsa mosebetsi li kena ho khopame ea lehae, e leng se bakang ho lutla ha matla a khoheli. Likaroloana tsa Magnetic tse kentsoeng ka holim'a lisebelisoa tsa mosebetsi li adsorbed, li etsa matšoao a bonahalang a khoheli tlas'a mabone a loketseng, ka hona a bonts'a sebaka, sebopeho le boholo ba li-discontinuities.
Tšebeliso le meeli:
Tlhahlobo ea likaroloana tsa Magnetic e loketse ho bona li-discontinuity holim'a metsi le haufi le holim'a lisebelisoa tsa ferromagnetic tse nyane haholo ebile li na le likheo tse moqotetsane haholo (joalo ka mapetsong a ka bonoang ka bolelele ba 0.1mm le bophara ba li-micrometer) tseo ho leng thata ho li lemoha. ka pono; E ka boela ea hlahloba lisebelisoa tse tala, lihlahisoa tse feliloeng, lisebelisoa tse felileng, le likarolo tsa ts'ebeletso, hammoho le lipoleiti, profil, liphaephe, mekoallo, likarolo tse cheselitsoeng, likarolo tsa tšepe tse entsoeng ka tšepe le likarolo tsa tšepe tse entsoeng. Litšitiso tse kang mapetsong, li-inclusions, li-hairlines, matheba a masoeu, mameno, li- shuts tse batang, le ho lokoloha li ka fumanoa.
Leha ho le joalo, tlhahlobo ea likaroloana tsa makenete ha e khone ho bona lisebelisoa tsa tšepe tse sa hloekang tsa austenitic le li-welds tse cheselitsoeng ka li-electrode tsa tšepe tse sa hloekang tsa austenitic, hape e ke ke ea bona lisebelisoa tse seng tsa makenete tse kang koporo, aluminium, magnesium, titanium, joalo-joalo. , le delamination le ho mena ka angle e ka tlase ho 20 ° ho tloha holim'a workpiece.
Teko ea Penetrant (PT)
Molao-motheo: Ka mor'a hore karolo e ka holimo ea karolo e kenngoe ka penetrant e nang le li-fluorescent kapa li-coloring dyes, tlas'a ketso ea tube ea capillary, ka mor'a nako e itseng, motho ea kenang ka hare a ka kenella ka har'a mefokolo ea ho bula holimo; Ka mor'a ho tlosa ho kenella ho feteletseng holim'a karolo, moqapi o sebelisoa holim'a karolo. Ka mokhoa o ts'oanang, tlas'a ts'ebetso ea capillary, moqapi o tla hohela motho ea ts'oaretsoeng ka phoso, 'me ea kenang o tla khutlela ho moqapi. Tlas'a mohloli o itseng oa leseli (ultraviolet kapa khanya e tšoeu), mesaletsa ea penetrant ka sekoli a hlokomela (bosehla bo botala fluorescence kapa bofubelu bo khanyang), ka tsela eo ho lemoha morphology le kabo boemo ba sekoli.
Melemo le meeli:
Teko e kenang ka hare e ka bona lisebelisoa tse fapaneng, ho kenyeletsoa lisebelisoa tsa tšepe le tse seng tsa tšepe; Lisebelisoa tsa Magnetic le tseo e seng tsa makenete; Welding, forging, rolling le mekhoa e meng ea ho lokisa; E na le kutlo e phahameng (e ka fumanoa e le 0.1 μ M sekoli se pharaletseng, e nang le ponts'o e hlakileng, ts'ebetso e bonolo, le litšenyehelo tse tlase tsa ho lemoha.
Empa e khona ho bona feela mefokolo e nang le menyetla e ka holimo 'me ha e tšoanelehe bakeng sa ho hlahloba li-workpieces tse entsoeng ka thepa ea porous le e hlephileng le li-workpieces tse nang le libaka tse thata; Ke kabo ea bokaholimo ba mefokolo feela e ka bonoang, e leng ho etsang hore ho be thata ho tseba botebo ba bofokoli, ho etsa hore ho be thata ho lekola mefokolo ka bongata. Liphetho tsa ho sibolloa le tsona li susumetsoa haholo ke opareitara.
