Ukwelashwa kokushisa okungaphezulu kubhekisela kwinqubo yokwelapha ukushisa kuphela ungqimba olungaphezulu lwensimbi. Ukwelashwa kokushisa okungaphezulu nakho kungathola isakhiwo esidingekayo se-metallographic kanye nezakhiwo zemishini.
Izindlela ezisetshenziswa kakhulu zokwelapha ukushisa komhlaba yilezi: ukucisha ukushisa kokungeniswa, ukucisha ukushisa kwelangabi, ukwelashwa kokushisa kwe-laser, ukucisha ukushisa kokuxhumana, ukucisha i-electrolyte, ukwelashwa kokushisa kwe-pulse, njll. Ngokwelashwa kokushisa okungaphezulu, ukubunjwa nezinye izingxenye zensimbi zingathola ungqimba olungaphezulu. ehlangabezana nezidingo zokusebenza.
Ngemuva kokuthi ungqimba oluqinile olungaphezulu lutholakala ngokushisisa nokucisha, umnyombo wokuphonsa usengagcina i-microstructure yasekuqaleni nokusebenza, ukuze kuzuzwe ukusebenza okuhle kakhulu okuphelele kokuthuthukisa amandla okukhathala, ukuthuthukisa ukumelana nokugqoka nokugcina ukuqina. Ngesikhathi esifanayo, ukwelashwa kokushisa okungaphezulu kunganciphisa ukusetshenziswa kwamandla futhi ngesikhathi esifanayo kunciphise ukuguqulwa kokucisha.
Ukuqina kokungeniswa kuyinqubo yokwelapha ukushisa esebenzisa umthelela wokushisa okhiqizwa amandla amanje okungenisa ngocezu lokusebenza ukushisa ingaphezulu lokulingisa, endaweni noma kukonke, bese kwenziwa ukupholisa okusheshayo. Izimiso eziyisisekelo zokushisa kwe-induction yilezi: ukungeniswa kwe-electromagnetic, umphumela wesikhumba kanye nokushisa kokushisa.
Izici Zokucisha Ukushisisa Okungeniswayo:
I-1) Ukucinywa kwe-induction kune-superplasticity. Ukuqina kobuso be-workpiece buyi-2-3 HRC ephakeme kunaleyo yokucisha okuvamile. Ngemuva kokushisa kokungeniswa nokucisha, i-martensite ye-casting incane futhi ama-carbides ahlakazeka.
I-2) Ukumelana nokugqoka kokusakazwa ngemuva kokucisha ukushisa kwe-induction kuphezulu kunokokucisha okuvamile.
3) Ngenxa yokuthi ingaphezulu le-workpiece lihle kakhulu i-cryptocrystalline martensite futhi kukhona ukucindezeleka okucindezelayo, amandla okukhathala kwe-workpiece athuthukiswa kakhulu.
I-4) Ikhwalithi ye-workpiece izinzile futhi i-deformation incane.
5) Isivinini sokushisa esisheshayo nokusebenza kahle kokushisa okuphezulu
6) Ukukhiqiza okuphezulu, kulula ukukubona ukukhiqizwa okwenziwe ngomshini
