Ukwelashwa okungaphezulu kuyinqubo yokwenza ungqimba olungaphezulu ngokuzenzela endaweni engaphansi kwe-substrate ehlukile emshinini, wezinto ezibonakalayo namakhemikhali we-substrate.Inhloso yokwelashwa kwendawo iwukuhlangabezana nokumelana nokugqwala, ukumelana nokuguga, ukuhlobisa noma ezinye izidingo ezikhethekile zokusebenza komkhiqizo.Ngokusakazwa kwensimbi, izindlela zokwelashwa ezivame ukusetshenziswa kakhulu ukupholisha ngomshini, ukwelashwa ngamakhemikhali, ukwelashwa kokushisa okungaphezulu, ukufafaza indawo engaphezulu, ukwelapha okungaphezulu ukuhlanza, ukuhlanza, ukukhipha, ukukhipha amafutha, i-deoxide, njll. endaweni yokusebenza.
I-Electrolysis iyinqubo lapho ukuhlanganiswa kwamakhemikhali ezinto ezihlanzeke kakhulu kanye nokwelashwa kwendawo ebonakalayo kwenziwa ukusabela kwe-electrochemical okwenzeka esibonakalayo phakathi kwe-electrode njengomqhubi we-elekthronikhi kanye ne-electrolyte njengomqhubi we-ion.
Ukupholisha kubhekisela ekusetshenzisweni komshini, amakhemikhali noma isenzo se-electrochemical ukuze kuncishiswe ubulukhuni obungaphezulu bomsebenzi ukuze kutholwe indlela yokucubungula indawo ekhanyayo neyisicaba.Kuwukusetshenziswa kwamathuluzi okupholisha nezinhlayiya ezilumayo noma enye imidiya yokupholisha ukuze kulungiswe indawo yokusebenza.
Inqubo ye-sandblasting isebenzisa umoya ocindezelwe njengamandla okwenza i-jet beam yesivinini esikhulu, futhi ifafaze izinto ezifuthwayo ebusweni bomsebenzi ozocutshungulwa ngesivinini esikhulu, ukuze ukubukeka kwendawo yangaphandle ye-workpiece kushintshe.Ngenxa yomthelela kanye nomphumela wokusika we-abrasive ebusweni be-workpiece, ingaphezulu le-workpiece Thola izinga elithile lokuhlanzeka kanye nobunzima obuhlukile, ukuze izakhiwo zemishini yendawo yokusebenza zithuthukiswe.
I-oxidation ibhekisela emandleni ento ukuthola ama-electron.Izinto ezisesimweni se-valence ephezulu kanye nezinto ezisebenzayo ezingezona ezensimbi (njenge-fluorine, i-chlorine, umoya-mpilo, njll.) ngokuvamile ziyi-oxidizing.Ukwelashwa kwe-oxidation kwezinsimbi wukusebenzelana kwendawo yensimbi ne-oxygen noma i-oxidant ukuze kwakhe ifilimu ye-oxide evikelayo ukuvimbela ukugqwala kwensimbi.
I-Electroplating yindlela yokwelapha engaphezulu kwensimbi ehlanganisa ukumboza ungqimba oluncane lwensimbi noma ingxubevange yensimbi engxenyeni yensimbi ukuvimbela ukugqwala kanye ne-oxidation yocezu lokusebenza, noma ukushintsha ukubukeka kwayo.Ithini, i-nickel, i-zinc (i-galvanized) ne-chromium zonke ziyizinsimbi ezivamile ze-electroplating, kuyilapho ithusi ne-carbon steel kuyizinsimbi ezimbili ezivame kakhulu ezisebenzisa izinqubo ze-electroplating.
Ukuqoshwa kwe-laser ukwenza amamaki anembile futhi ahlala njalo ezinsimbi namapulasitiki athile.
Ukugaya okwenziwa ngesandla kungasusa izimpawu zomshini, kususe ama-burrs ebusweni bezingxenye, imigqa yokukhiqiza kanye nezimpawu zokunamathela kanye nezinye iziphambeko zomkhiqizo.I-flatness yezingxenye izothuthukiswa futhi ukugoqa kuzoncishiswa ukuze kuzuzwe indawo yokubukeka ebushelelezi futhi engaguquki.
