Ama-electrode okushisela amelela isigaba esikhethekile sezinto ezisetshenziswayo zokushisela ezenzelwe ukuvikela ubuso nokubuyiselwa kwezingxenye. I-electrode ye-Ni307-2, evumelana nokuhlukaniswa kwe-AWS A5.11 ENiCrFe-2, iyisibonelo salesi sigaba ngokwakheka kwayo kwesisekelo se-nickel kanye nezici ezithile zobuchwepheshe. Le electrode inesistimu yokumboza i-sodium ephansi futhi isebenza ku-DCEP (Direct Current Electrode Positive), okwenza ifaneleke ukusetshenziswa lapho kudingeka khona izici zokubeka ezilawulwayo kanye nokuqukethwe okuncane kwe-hydrogen. Lezi zakhiwo ziyibeka njengesixazululo esisebenzayo sezimo ezahlukahlukene zokugcinwa kwezimboni.
Ukwakheka okuyisisekelo kwalokhuama-electrode okushiselaUmkhiqizo usekelwe ohlelweni lwe-alloy ye-nickel-chromium-iron. Le nhlanganisela ye-metallurgical inikeza izakhiwo ezilinganiselayo kufaka phakathi ukumelana okuhle nokugqwala kanye ne-oxidation, kanye namandla ahlala ekhona emazingeni okushisa aphezulu. Isisekelo se-nickel-base sinikeza ukuqina okuphezulu uma kuqhathaniswa nama-electrode avamile asekelwe ensimbini, okunciphisa ukuthambekela kokuqhekeka ngaphansi kwezimo zokucindezeleka kokushisa. Ibhalansi ethile ye-alloy iqinisekisa ukuhambisana nezinto ezahlukahlukene eziyisisekelo ngenkathi iletha izakhiwo ezidingekayo zomphezulu.
Isici esibalulekile salokhuama-electrode okushiselaIzinto zokwakha ziyindlela yokwakheka kwe-hydrogen sodium ephansi. Lolu hlobo lwe-coating lunciphisa ngempumelelo okuqukethwe kwe-hydrogen ensimbini efakiwe, ngaleyo ndlela lunciphise ingozi yokuqhekeka okubangelwa yi-hydrogen engqimbeni eqinile. I-coating iphinde ibe negalelo ezicini ze-arc ezizinzile, ukudluliselwa kwensimbi okubushelelezi, kanye nokuhlukaniswa kwe-slag okuhle. Isidingo se-DCEP polarity siqinisekisa ukuzinza kwe-arc okufanele kanye nezici zokungena ngenkathi kuthuthukiswa ukusebenza kahle kwe-deposition ngesikhathi senqubo yokushisela.
Amapharamitha okusebenza ale mikhiqizo ye-hardfacing yama-electrode okushisela afaka izici zokubeka ezilawulwayo kanye nokusebenza kahle kokushisela okulawulekayo. Ama-electrode aklanyelwe ukukhiqiza amadiphozithi aminyene, asezingeni eliphezulu anokuchitheka okuncane kanye nephrofayili yobuhlalu obulawulwayo. Insimbi yokushisela ephumayo ingashintshwa ngomshini kusetshenziswa izindlela ezivamile, okuvumela ukulungiswa kobukhulu kanye nokuqedwa kwendawo lapho kudingeka. Lezi zici zenza i-electrode ifanele ukusetshenziswa lapho kokubili ukusebenza kwesendlalelo esiqinile kanye nesimo sayo sokugcina sobuso kuyizinto ezibalulekile okufanele zicatshangelwe.
Ezisetshenzisweni ezisebenzayo, lezi zisekelo ze-nickelama-electrode okushiselaIzinto zokwakha zisebenza ekulungiseni izingxenye kanye nezindima zokuvikela ubuso emikhakheni eyahlukene yezimboni. Izicelo ezijwayelekile zifaka phakathi ukwakha kabusha izingxenye ezigugile ezisebenza ezindaweni zokushisa eziphakeme, ukuhlanganisa izinsimbi ezingafani nezici ezahlukene zokukhulisa ukushisa, kanye nezindawo zokumboza ezidinga ukumelana nokugqwala kanye namandla omshini. Izici zobuchwepheshe kanye nezici zokusebenza kwenza lawa ma-electrode asebenze ezimweni zokulungisa kanye nokukhiqiza lapho kudingeka khona ukuvikelwa kobuso okuhlala isikhathi eside kanye nokubuyiselwa kwezingxenye.
