Isixhobo sedayimani sokufakelwa ngombane
Ukuplatwa kwezixhobo zedayimani yinkqubo yokufaka i-electrode kwisinyithi esisisiseko (esifana ne-nickel okanye i-cobalt) kwisiseko (esifana nentsimbi) ukuze sijikeleze amasuntswana edayimani ngokuqinileyo. Esi sixhobo sedayimani esifakwe nge-electrode sinikezela ngeenzuzo ezininzi, kubandakanya ukumelana nokuguguleka okugqwesileyo, ubulukhuni obuphezulu, kunye nokusebenza kakuhle kokusika okanye ukugawula. Ezifana nokuidiski yeflap, iphepha lokusanti, ibhanti yokusantisa, idiski yokusantisa, njl. Ukusetyenziswa kweplating yezixhobo zedayimani kusetyenziswa kakhulu kumashishini ahlukeneyo. Kwishishini loomatshini, ezi zixhobo zisetyenziswa kakhulu ekubholeni, ekusikeni nasekugayeni. Kwishishini le-elektroniki, zisetyenziselwa umatshini ochanekileyo wezixhobo ze-elektroniki. Ishishini leglasi lisebenzisa iplating yezixhobo zedayimani ukusika, ukubumba kunye nokugaya iimveliso zeglasi. Kwishishini lokwakha, ezi zixhobo zisetyenziselwa ukusika nokupolisha izixhobo zokwakha ezifana neethayile zekhonkrithi okanye zeseramikhi. Ukongeza, iplating yezixhobo zedayimani ikwasetyenziswa kakhulu kwiinkqubo zokumba kunye nokugqiba kwishishini lokumba ioyile. Ngokubanzi, izixhobo zedayimani ezifakwe ngombane ziphucula ukusebenza kwazo kwaye zandisa ukusetyenziswa kwazo kumacandelo ahlukeneyo emizi-mveliso.
Kuluntu lwanamhlanje olukhula ngokukhawuleza kwezobuchwepheshe obuphezulu, isidingo sezixhobo ezisebenzayo nezihlala ixesha elide sibalulekile kumashishini ahlukeneyo. Izixhobo zedayimani ezifakwe ngombane ziyindlela ethandwayo ngenxa yokusebenza kwazo okuphezulu. Nangona kunjalo, nangona ezi zibonelelo, abasebenzisi badla ngokudibana nemingeni enciphisa ukusebenza kwazo kunye nobomi benkonzo. Enye yeengxaki ezinkulu ezijongene nabasebenzisi kukukhuhla kancinci kancinci kwengubo esetyenziswa kwizixhobo zedayimani ezifakwe ngombane. Oku kunokubangela ukwehla okukhulu ekusebenzeni kwesixhobo kwaye kuchaphazele kakhulu ubomi benkonzo yaso iyonke. Kweli nqaku, siza kuphonononga ezinye zeengxaki ezixhaphakileyo ezinxulumene nezixhobo zedayimani ezifakwe ngombane kwaye sixoxe ngezisombululo ezisebenzayo zokoyisa ezi ngxaki.
Ungayikhetha njani idayimani?
Ubumsulwa: Khangela iidayimani ezicocekileyo kangangoko. Iidayimani ezicocekileyo azinambala kwaye azibonakali, zinombala otyheli-luhlaza. Ziphephe iidayimani ezinee-inclusions ezininzi, njengoko zinokubonakala zingwevu-luhlaza okanye zibe neminye imibala. Iidayimani ezine-boron maziphetshwe kuba ziya kubonakala zimnyama.
Ulwakhiwo: Hlola ulwakhiwo lwedayimani usebenzisa imakroskopu ye-metallographic. Iidayimani zendalo zihlala zithatha uhlobo lwee-octahedron, ii-rhombohedral dodecahedrons, iityhubhu okanye ii-aggregates. Iidayimani ezenziwe ngabantu zinokubonakala ngokwahlukileyo. Ukungcola nokungapheleli: Kuphephe ukusebenzisa iidayimani ezinokungcola nokungapheleli okubonakalayo njengoko zinokuchaphazela ukusebenza kunye nokuqina kwesixhobo sakho sedayimani. Ukungcola kunokwenza idayimani ibe buthathaka kwaye kwenze ukuba ingasebenzi kakuhle ekusikeni.
Umgangatho weDayimani: Iqwalasela umgangatho opheleleyo wedayimani ngokwemibala, ukucaca, ukunqunyulwa, kunye nobunzima be-carat. Nangona ezi zinto zihlala zinxulunyaniswa needayimani ezisemgangathweni welitye elinqabileyo, zinokuchaphazela ukufaneleka kwedayimani ekusebenziseni kwizixhobo. Khetha iidayimani ezinombala ongcono kunye namanqanaba okucaca ukuze usebenze ngcono.
Indlela yokusebenzisa: Qonda iimfuno ezithile zesixhobo sedayimani ocinga ngaso. Iimpawu kunye nobukhulu obahlukeneyo bedayimani bunokufaneleka kwimisebenzi eyahlukeneyo. Umzekelo, idayimani enkulu ecacileyo kancinci kodwa enamandla aphezulu isenokufaneleka ngcono kwizicelo ezinzima, njengokugqobhoza izinto eziqinileyo, ngelixa idayimani encinci, ecacileyo ngakumbi isenokufaneleka ngakumbi ekusikeni ngokuchanekileyo.
Ungayisombulula njani ingxaki yokuwa kwezixhobo zokugquma?
Izixhobo zokugquma zidlala indima ebalulekileyo kumashishini amaninzi, ziqinisekisa ukusebenza kakuhle kunye nokuchaneka kwiinkqubo ezahlukeneyo. Nangona kunjalo, ingxaki ekudala ikhathaza abavelisi kunye nabasebenzisi yingxaki yezixhobo ezigqumayo eziqhekekayo. Ukunciphisa le ngxaki, iingcali ziye zacebisa izisombululo ezininzi ezisebenzayo, zigxile ekwenzeni ngcono inkqubo ye-electroplating kunye nokuphucula amandla okubopha phakathi kwengubo kunye ne-substrate.
Okokuqala, ukuphucula umgangatho jikelele wengubo, ifomula yesisombululo seplating kunye nenkqubo ye-electroplating kufuneka iphuculwe. Ngokusebenzisa iteknoloji yokutshaja bukhoma, abavelisi banokuthintela ngempumelelo i-bipolarity, enciphisa amandla okubopha kwengubo. Ukongeza, kwizinto zokusebenza ezineemilo ezintsonkothileyo, ukusetyenziswa kwengubo yomoya enefuthe lexesha elifutshane kuye kwabonakala kuluncedo. Le teknoloji inceda ekunciphiseni imiphumo yoxinzelelo lwangaphakathi kunye nokuguquka kwe-hydrogen, okubangela ukuba ingubo ibe semgangathweni ophezulu engenakukwazi ukukrazuka.
Okwesibini, unyango oluphuculweyo lwe-pre-plating lubalulekile ukukhuthaza ukunamathelana okufanelekileyo phakathi kwesinyithi esigqumayo kunye nesinyithi esisisiseko. Ii-Burrs, amabala eoyile, iifilimu ze-oxide, umhlwa kunye nesikali kumphezulu we-substrate kufuneka zisuswe ngokupheleleyo. Ngokwenza njalo, ukukhula okuqhelekileyo kwe-lattice yesinyithi yesigqumayo kuyakhuthazwa, ngaloo ndlela kuphucula kakhulu amandla okubopha ngokubanzi.
Ukongeza, ukuba kukho ukucima kombane ngexesha lenkqubo yokutyeba, kucetyiswa amanyathelo athile ukuqinisekisa ukuba i-workpiece igcina i-coating eqinileyo. Kule meko, i-workpiece kufuneka ibekwe kwi-electrolyte ukuze kuncitshiswe i-cathodic. Emva kokuba inkqubo yokunciphisa igqityiwe, i-workpiece ifakwa etankini ukuze ifake i-electroplating ukuqinisekisa amandla okubopha afunekayo e-coating. Kufuneka kugxilwe ekuphuculeni itekhnoloji kunye neenkqubo kwinkqubo yokususa isanti ukuze kuncitshiswe ixesha lokucima kombane. Ngokunciphisa ukucima kombane, isanti ingasuswa amanzi kwaye igxininiswe kwi-santi yokuqala okanye ye-backup. Oku kuqinisekisa ukuphuculwa kokubopha phakathi kwamasuntswana edayimani kunye ne-coating, kwandisa ukuqina kunye nokunciphisa amathuba okuchithakala.
Ezi zisombululo zicetywayo zijolise ekusombululeni ingxaki ekudala ikho yokucinywa kwezixhobo ezigqunyiweyo. Ngokusebenzisa iindlela zokucwangcisa ezilungisiweyo, ukuphucula unyango lwangaphambi kokucwangcisa, kunye nokusebenzisa amanyathelo okulungisa asebenzayo ngexesha lokucima, abavelisi banokuwuphucula kakhulu umgangatho kunye namandla eengubo zabo zokugqunywa. Le mizamo iya kuphucula ngakumbi ukusebenza kunye nokuthembeka kwezixhobo ezigqunyiweyo, ukuqinisekisa imveliso efanelekileyo kunye nokunciphisa iindleko zokugcinwa kwamashishini axhomekeke kwezi zixhobo.
