1. Izinga lokushisa lokwelapha lokushisa kwamakhemikhali endabuko
Izinqubo ezijwayelekile zokwelapha ukushisa kwamakhemikhali zifaka i-carburizing ne-nitriding, futhi izinga lokushisa lenqubo linqunywa ngokuya ngomdwebo wesigaba se-Fe-C kanye nomdwebo wesigaba se-Fe-N.Izinga lokushisa le-carburizing licishe libe ngu-930 °C, kanti izinga lokushisa le-nitriding licishe libe ngu-560 °C.Izinga lokushisa le-ion carburizing kanye ne-ion nitriding nalo lilawulwa ngokuyisisekelo kuleli banga lokushisa.
2. Ukushisa okuphansi kwe-ion amakhemikhali okushisa ukushisa ukushisa
Ukwelashwa kokushisa kwamakhemikhali e-ionic asezingeni eliphansi ubuchwepheshe obusha obuthuthukiswe eminyakeni yamuva nje ukuze kuhlangatshezwane nezidingo zokuthuthukiswa kokukhiqiza.Izinga lokushisa eliphansi le-ion carburizing lokushisa ngokuvamile lingaphansi kuka-550C, futhi izinga lokushisa eliphansi le-ion nitriding lezinga lokushisa livamise ukuba ngaphansi kuka-450°C.
3. Uhla lokusebenza lokwelashwa kokushisa kwamakhemikhali e-ionic asezingeni eliphansi
(1) Insimbi engagqwali yezinga lokushisa eliphansi lokwelashwa kwe-ionochemical: ukumelana nokugqwala kwendawo yensimbi engagqwali ngemva kokwehliswa kokwelashwa okujwayelekile kokushisa kwe-ionochemical.Ukusetshenziswa kokwelashwa kokushisa kwamakhemikhali e-ionic aphansi okushisa kungathuthukisa ubulukhuni bobuso ngesisekelo sokuqinisekisa ukuthi imikhiqizo yensimbi engagqwali ayigqwali futhi isagcina umphumela omuhle wokuhlobisa phezulu.
(2) Ukwelashwa kokushisa okuphansi kwe-ionochemical kwesikhunta: imakethe idinga izinga lokushisa eliphansi le-ion nitriding phezu kwezibungu ezisindayo ngaphambi kokufaka izimbotshana eziqinile ukuze kwakheke ungqimba oluqinile lokuguquka kwe-gradient phakathi kwe-matrix ne-hard coating, ngaleyo ndlela ibe ngcono ngempumelelo. ukumelana komthelela kwesikhunta;Ngaphezu kwalokho, ukuze kuqinisekiswe ukunamathela okuhle koqweqwe oluqinile, ungqimba lwe-nitriding njengongqimba lwenguquko yobulukhuni akumele lube nendawo ekhanyayo nehlanzekile kuphela, kodwa futhi alukwazi ukwakha ungqimba oluhlanganisiwe olukhanyayo olumhlophe.
Ukuthuthukiswa komkhakha wokucubungula okuphezulu kukhuthaze ukuzalwa nokuthuthukiswa kokwelashwa kokushisa kwamakhemikhali e-ion aphansi.
