Isifutho Esishisayo siyindlela yokumboza efutha into efudumele phezu kwendawo ukuze iyimboze futhi yenze ikwazi ukuguguleka, ukugqwala, ukuguguleka, ukushaqeka noma ukumelana nokuvuvukala. Izinto ezahlukahlukene zingasetshenziswa ekufutheni okushisayo, kodwa izinto ezintathu ezivame kakhulu yizinsimbi, izinto zobumba kanye nepulasitiki. Izinto (noma isitokwe sokudla) zifudunyezwa ngogesi (i-plasma noma i-arc) noma izindlela zamakhemikhali (ilangabi lokusha) ukuze kube umfudlana wezinhlayiya ezihlukaniswe ngesivinini esikhulu esimweni esincibilikisiwe noma esincibilikisiwe kancane esithinta isisekelo ukuze kukhiqizwe isimbozo. Isitokwe sokudla singaba ngesimo senduku, ucingo, impuphu noma uketshezi.
Isifutho sokushisa sivame ukwenziwa ukuvikela noma ukulungisa izinto ezingaphandle. Enye inzuzo yesifutho sokushisa ukuthi simboza izinto ezingaphandle ngesithiyo esivikelayo. Isibonelo, indawo embozwe ngensimbi eqinile izoba namandla kakhulu ekugugeni, ekushiseni, nasekuklwebhekeni. Enye inzuzo ukuthi isifutho sokushisa singalungisa izinto ezingaphandle. Ingxenye egugile noma ebolile ingafuthwa ngezifutho ukuze ibuyiselwe. Nakuba ifutho lokushisa lingangezi amandla engxenyeni, kuyindlela esheshayo neyongayo yokulungisa ubukhulu bezingxenye. Imisebenzi yokugaya elandelayo ivame ukudingeka ukuze kusheleleze indawo yezifutho futhi kulethwe ubukhulu bokugcina ekubekezeleleni kwabo okufanele.Amabhande okusantisa idayimanezisetshenziswa kabanzi emisebenzini yokugaya.
Izinzuzo eziyinhloko kanye nezici zesifutho sokushisa njengenqubo yokumboza zifingqiwe ngezansi:
● Akudingi noma yiziphi izinto eziphilayo eziguquguqukayo (ama-VOC) eziyingozi kubantu kanye nemvelo.
● Izinto eziphelele zingasetshenziswa njengezinto zokudla: izinsimbi, ama-alloy, izinto zobumba, ama-cermets, ama-carbide, ama-polymers kanye namapulasitiki.
● Izembozo zokufutha ezishisayo ziboshelwe ngomshini ku-substrate. Zingafutha izinto zokufutha ezingahambisani ne-substrate ngokwensimbi.
● Ingafafaza izinto zokumboza ngephuzu lokuncibilika eliphakeme kune-substrate.
● Izembozo zokufutha ezishisayo zingasetshenziswa ngesandla nangokusebenzisa imishini.
● Ukufakwa kwezembozo ezijiyile kungasetshenziswa ngamanani aphezulu okufakwa.
● Izingxenye eziningi zingafuthwa ngokushisa okuncane noma ngaphandle kokushisa kwangaphambi noma kokushisa kwangemva kokushisa, futhi ukuphambuka kwezingxenye kuncane kakhulu.
● Izingxenye zingakhiwa kabusha ngokushesha nangezindleko eziphansi, futhi ngokuvamile ngentengo encane kakhulu kuneyokushintshwa.
● Ngokusebenzisa izinto ezisezingeni eliphezulu zokufaka isifutho sokushisa, isikhathi sokuphila sezingxenye ezintsha singandiswa.
Kunezinhlobo eziningana ezahlukene zezinqubo zokumboza nge-thermal spray. Ziyahlukahluka ngendlela ezisebenzisa ngayo amandla okushisa kanye ne-kinetic ezintweni ezitholakala kumthombo, uhlobo lwezinto ezitholakala kumthombo kanye nesivinini esihlobene kanye namazinga okushisa elangabi. Inqubo ngayinye inezinzuzo kanye nokungalungi, kanti ezinye zilungiselelwe izinhlobo ezithile zokumboza.
Izinqubo zokufutha ngokushisa ziye zasetshenziswa kabanzi iminyaka eminingi kuyo yonke imikhakha emikhulu yobunjiniyela okuhlanganisa ukukhiqizwa kwama-turbine egesi, izinjini zikadizili, ama-bearings, amajenali, amaphampu, ama-compressor kanye nemishini yasensimini kawoyela, kanye nokufaka izinsimbi zezokwelapha. Imishini yakamuva kanye nentuthuko yenqubo kuthuthukise ikhwalithi futhi kwandise ububanzi bokusetshenziswa okungenzeka kwezingubo zokufutha ngokushisa.
