Izinga lidinga ukuthi ukwakheka kwe-crimping kwetheminali yesixhumi kufanelekile yini. I-porosity ye-terminal crimping wire ibhekisela esilinganisweni sendawo engaxhunywanga ye.ingxenye exhumayo kutheminali ye-crimping endaweni ephelele, okuyipharamitha ebalulekile ethinta ukuphepha nokuthembeka kwetheminali ye-crimping. I-porosity ephezulu kakhulu izoholela ekuthinteni okungalungile, ukwandisa ukumelana nokushisa, ngaleyo ndlela kuthinte ukuzinza nokuphepha kokuxhumeka kukagesi. Ngakho-ke, imishini yokuhlaziya i-metallographic iyadingeka ukuze kutholwe i-porosity engaphezulu nokuhlaziywa. Ukusikwa kwesampula ye-Metallographic, umshini wesampula we-metallographic wokugaya nokupholishwa, kanye nesibonakhulu se-metallographic kuyadingeka ukuze kusampula futhi kulungiswe itheminali, bese umfanekiso wesithombe uhlaziywa ngesofthiwe ye-metallographic microscope ukuze kuhlolwe i-terminal cross-section.
Inqubo yokulungiselela isampula: Isampula okufanele lihlolwe (izimbambo eziqinisayo zetheminali kufanele zigwenywe) liyasikwa futhi lithathwe ngomshini wokusika isampula ye-metallographic-kunconywa ukuthi kusetshenziswe umshini wokusika onembile ukuze usike, bese ucwecwe olutholiwe lufakwe kusampula enamapulatifomu amabili kusetshenziswa umshini wokufakela i-metallographic, bese indawo yokuhlola ehlanganisiwe idinga ukugaywa futhi icwebezeliswe indawo yamakhemikhali egayiwe bese igaywa ngensimbi. igqwalile futhi ibekwe ngaphansi kwesibonakhulu se-metallographic ukuze ihlolwe futhi ihlaziywe.
