Ukufakwa kwe-electroplating yamathuluzi edayimane
Ukufakwa kwensimbi yedayimane kuyinqubo yokufaka insimbi eyisisekelo (njenge-nickel noma i-cobalt) ku-substrate (njengensimbi) ukuze izungeze izinhlayiya zedayimane ngokuqinile. Leli thuluzi ledayimane elifakwe nge-electrode linikeza izinzuzo eziningana, kufaka phakathi ukumelana okuhle kakhulu nokuguguleka, ubulukhuni obuphezulu, kanye nokusebenza kahle kokusika noma ukugaya. Njengokuthiidiski yeflap, iphepha lokusanta, ibhande lokusanta, idiski yokusantisa, njll. Ukusetshenziswa kwe-diamond tool plating kusetshenziswa kabanzi ezimbonini ezahlukene. Embonini yemishini, la mathuluzi avame ukusetshenziswa ekubholeni, ekusikeni nasekugayeni. Embonini ye-elekthronikhi, asetshenziselwa ukukhanda ngokunemba izingxenye ze-elekthronikhi. Imboni yengilazi isebenzisa i-diamond tool plating ukusika, ukuma nokugaya imikhiqizo yengilazi. Embonini yokwakha, la mathuluzi asetshenziselwa ukusika nokupholisha izinto zokwakha ezifana namathayela ekhonkrithi noma e-ceramic. Ngaphezu kwalokho, i-diamond tool plating nayo isetshenziswa kabanzi ezinqubo zokubhoboza nasekuqedeni embonini yokubhoboza uwoyela. Sekukonke, amathuluzi edayimane afakwe ngogesi athuthukisa ukusebenza kwawo futhi andise ukusetshenziswa kwawo emikhakheni ehlukene yezimboni.
Emphakathini wanamuhla othuthuka ngokushesha kwezobuchwepheshe obuphezulu, isidingo samathuluzi asebenzayo futhi ahlala isikhathi eside sibalulekile ezimbonini ezahlukahlukene. Amathuluzi edayimane afakwe ngogesi ayisinqumo esithandwayo ngenxa yokusebenza kwawo okuphezulu. Kodwa-ke, naphezu kwalezi zinzuzo, abasebenzisi bavame ukubhekana nezinselele ezinciphisa ukusebenza kahle kwabo kanye nempilo yesevisi. Enye yezinkinga ezinkulu ezibhekene nabasebenzisi ukukhuhla kancane kancane kwesembozo esisetshenziswa kumathuluzi edayimane afakwe ngogesi. Lokhu kungabangela ukwehla okukhulu ekusebenzeni kwamathuluzi futhi kuthinte kakhulu impilo yawo yesevisi iyonke. Kulesi sihloko, sizohlola ezinye zezinkinga ezivame ukuhlangana nazo ezihlobene namathuluzi edayimane afakwe ngogesi futhi sixoxe ngezixazululo ezisebenzayo zokunqoba lezi zinkinga.
Ungayikhetha kanjani idayimane?
Ubumsulwa: Funa amadayimane amsulwa ngangokunokwenzeka. Amadayimane amsulwa awanombala futhi acacile, anombala ophuzi oluhlaza ojwayelekile. Gwema amadayimane anezinhlanganisela eziningi, njengoba angase abonakale eluhlaza okotshani noma abe neminye imibala. Amadayimane aqukethe i-boron kufanele agwenywe njengoba azobonakala emnyama.
Isakhiwo: Hlola isakhiwo sedayimane ngaphansi kwe-microscope ye-metallographic. Amadayimane emvelo avame ukuthatha isimo sama-octahedron, ama-rhombohedral dodecahedrons, ama-cubes noma ama-aggregates. Amadayimane enziwe ngabantu angaba nokubukeka okuhlukile. Ukungcola kanye nokungapheleli: Gwema ukusebenzisa amadayimane anokungcola okubonakalayo kanye nokungapheleli njengoba kungathinta ukusebenza kanye nokuqina kwethuluzi lakho ledayimane. Ukungcola kungenza idayimane libe buthaka futhi kwenze lingasebenzi kahle ekusikeni.
Ikhwalithi Yedayimane: Icabangela ikhwalithi iyonke yedayimane ngokuya ngombala, ukucaca, ukusika, kanye nesisindo se-carat. Nakuba lezi zici zivame ukuhlotshaniswa namadayimane ekhwalithi yamatshe ayigugu, zingathinta nokufaneleka kwedayimane ukusetshenziswa kumathuluzi. Khetha amadayimane anombala ongcono kanye namazinga okucaca ukuze kuthuthukiswe ukusebenza.
Isicelo: Qonda izidingo ezithile zesicelo sethuluzi ledayimane ocabanga ngalo. Izimfanelo nobukhulu obuhlukene bedayimane kungafaneleka emisebenzini ehlukene. Isibonelo, idayimane elikhulu elinokucaca okuncane kodwa elinamandla aphezulu lingafaneleka kangcono ekusetshenzisweni okunzima, njengokubhoboza izinto eziqinile, kuyilapho idayimane elincane, elisobala kakhulu lingafaneleka kangcono ekusikeni ngokunembile.
Ungayixazulula kanjani inkinga yokuwa kwamathuluzi okumboza?
Amathuluzi okumboza adlala indima ebalulekile ezimbonini eziningi, ukuqinisekisa ukusebenza kahle nokunemba ezinqubweni ezahlukene. Kodwa-ke, inkinga ende ebilokhu ihlupha abakhiqizi nabasebenzisi inkinga yamathuluzi ambozwe aqhephukayo. Ukuze kuncishiswe le nkinga, ochwepheshe baphakamise izixazululo eziningana ezisebenzayo, ezigxile ekwenzeni ngcono inqubo ye-electroplating kanye nokuthuthukisa amandla okubopha phakathi kokumboza kanye ne-substrate.
Okokuqala, ukuze kuthuthukiswe ikhwalithi iyonke yengubo, ifomula yesisombululo se-plating kanye nenqubo ye-electroplating kumele kwenziwe ngcono. Ngokusebenzisa ubuchwepheshe bokushaja bukhoma, abakhiqizi bangavimbela ngempumelelo i-bipolarity, okwenza buthaka amandla okubopha kwengubo. Ngaphezu kwalokho, ezintweni zokusebenza ezinezimo eziyinkimbinkimbi, ukusetshenziswa kwengubo yomoya enamandla yesikhathi esifushane kuye kwabonakala kuwusizo. Lobu buchwepheshe buyasiza ekunciphiseni imiphumela yokucindezeleka kwangaphakathi kanye nokuvela kwe-hydrogen, okuholela enguboni yekhwalithi ephezulu okungenzeka ukuthi ihlubuke.
Okwesibili, ukwelashwa okuthuthukisiwe kokufaka i-plating kubalulekile ukukhuthaza ukunamathela okufanele phakathi kwensimbi yokumboza kanye nensimbi eyisisekelo. Ama-Burrs, amabala kawoyela, amafilimu e-oxide, ukugqwala kanye nesikali ebusweni be-substrate kumele kususwe ngokuphelele. Ngokwenza kanjalo, ukukhula okuvamile kwe-lattice yensimbi yokumboza kukhuthazwa, ngaleyo ndlela kuthuthukiswe kakhulu amandla okubopha jikelele.
Ngaphezu kwalokho, uma kwenzeka ukucima kukagesi ngesikhathi senqubo yokujiya, kunconywa izinyathelo ezithile ukuqinisekisa ukuthi i-workpiece igcina i-coating eqinile. Kulesi simo, i-workpiece kufanele ifakwe ku-electrolyte ukuze kuncishiswe i-cathodic. Ngemva kokuba inqubo yokunciphisa isiqediwe, i-workpiece ifakwa ethangini ukuze ifake i-electroplating ukuqinisekisa amandla okubopha adingekayo e-coating. Kufanele futhi kugxilwe ekwenzeni ngcono ubuchwepheshe kanye nezinqubo enkambisweni yokususa isihlabathi ukuze kuncishiswe isikhathi sokuphela kukagesi. Ngokunciphisa ukucima kukagesi, isihlabathi singakhishwa amanzi futhi sigxishwe ethangini lesihlabathi lokuqala noma eliyisipele. Lokhu kuqinisekisa ukuhlanganiswa okuthuthukisiwe phakathi kwezinhlayiya zedayimane kanye ne-coating, kwandisa ukuqina kanye nokunciphisa amathuba okuchitheka.
Lezi zixazululo eziphakanyisiwe zihlose ukuxazulula inkinga yesikhathi eside yokuchitheka kwamathuluzi ambozwe nge-coated. Ngokusebenzisa amasu okufaka i-coated alungiselelwe, ukuthuthukisa ukwelashwa kwangaphambi kokufaka i-coated, kanye nokusebenzisa izindlela zokulungisa ezisebenzayo ngesikhathi sokungasebenzi, abakhiqizi bangathuthukisa kakhulu ikhwalithi namandla okufaka i-coated yabo. Le mizamo izothuthukisa ukusebenza nokuthembeka kwamathuluzi ambozwe nge-coated, iqinisekise ukukhiqiza okuhle kakhulu futhi inciphise izindleko zokulungisa izimboni ezithembele kula mathuluzi.
