Amathuluzi e-Electroplated Diamond afaka izinqubo eziningi kwinqubo yokukhiqiza, noma iyiphi inqubo ayanele, izokwenza ukuba ukuhlanganiswa kuwa.
Umphumela wokwelashwa kwangaphambi kokuthambisa
Inqubo yokwelashwa ye-matrix yensimbi ngaphambi kokungena ethangi lokuthwebula ibizwa ngokuthi ukwelashwa kwangaphambi kwamapuleti. Ukwelashwa kwangaphambi kokuthambisa kufaka phakathi: I-Mechanical Polishing, Ukususwa Kowoyela, Ukuguguleka kanye Nezinyathelo Zokusebenza. Inhloso yokwelashwa kwangaphambi kokuthambisa ukususa i-burr, uwoyela, ifilimu oxide, ukugqwala kanye nesikhumba se-oxidation ebusweni be-matrix, ukuze kudalule insimbi ye-matrix ukukhulisa amandla ensimbi ngokujwayelekile futhi akha amandla okubopha ama-intermolecular.
Uma ukwelashwa kwangaphambi kokuthambisa akukuhle, ingaphezulu le-matrix linefilimu elincanyana kakhulu lefilimu ne-ongide, umlingiswa wensimbi we-matrix awukwazi ukudalulwa ngokugcwele, okuzovimba ukwakheka kwensimbi yensimbi ne-matrix kuphela, okuwohloka amandla ampofu. Ngakho-ke, ukucaca okungekuhle ngaphambi kokuba i-plating iyimbangela eyinhloko yokuchitheka.
Umphumela weplanethi
Ifomula yesixazululo se-platiating ithinta ngqo uhlobo, ubunzima futhi igqoke ukumelana kwensimbi ye-coating. Ngamapharamitha enqubo ahlukene, ubukhulu, ubungako kanye nengcindezi ye-coating metal crystallization nayo ingalawulwa.
Ukuze kukhiqizwe amathuluzi we-Diamond Electroplating, abantu abaningi basebenzisa i-nickel noma i-nickel-cobalt alloy. Ngaphandle kwethonya lokungcoliswa kokungcoliswa, izici ezithinta ukuchitheka kwe-coating yilezi:
.
Ukuxineka kwe-macroscopic kungadala ama-bubble, ukuqhekeka nokuwa enhlanganisweni kwinqubo yokugcina nokusebenzisa.
Ngokuthwebula ama-nickel noma i-nickel-cobalt alloy, ukucindezela kwangaphakathi kuhluke kakhulu, okuphezulu kakhulu kwe-chloride, kukhulu ukucindezela kwangaphakathi. Ngosawoti ophambili wekhambi le-nickel sulfate coating coating, ukucindezelwa kwangaphakathi kwesixazululo se-watt coating kungaphansi kwenye isixazululo se-Coatings. Ngokwengeza i-organic ekhuthele noma ukuqeda ingcindezi ukucindezela, ukucindezelwa kwangaphakathi kwe-macro of the coating kungancishiswa kakhulu futhi ukucindezelwa kwangaphakathi okuningi kungandiswa.
. Ngakho-ke, ngaphansi kwezimo ezifanele, kungakhathalekile ukuthi i-electrolyte ye-acidic, engathathi hlangothi, noma i-alkali, kuvame ukuba nemvula ye-hydrogen e-cathode kanye nemvula yensimbi. Ngemuva kokuthi i-hydrogen ion inciphise e-cathode, ingxenye ye-hydrogen iphunyuke, futhi ingxenye ye-apps ibe yi-matrix yensimbi kanye ne-coating esimweni se-athomu hydrogen. Ihlanekezela i-lattice, ibangele ukucindezelwa okukhulu kwangaphakathi, futhi yenza ne-coaring ichitheke kakhulu.
Imiphumela yenqubo yokuqoqa
Uma ukwakheka kwesisombululo se-electroplating kanye neminye imiphumela yokulawula inqubo ayifakwanga, ukwehluleka kwamandla kwinqubo ye-electroplating kuyimbangela ebalulekile yokulahleka kwe-coating. Inqubo yokukhiqiza i-electroplating ye-electroplating amathuluzi edayimane ihluke kakhulu kwezinye izinhlobo ze-electroplating. Inqubo yokuqoqa amathuluzi e-electroing amathuluzi afaka amathuluzi angenalutho (isisekelo), ukuhlanganiswa kwesihlabathi kanye nenqubo yokuqina. Kunqubo ngayinye, kungenzeka ukuthi i-matrix ishiya ikhambi le-plating, okungukuthi, ukuphuma kwamandla okufushane noma okufushane. Ngakho-ke, ukusetshenziswa kwenqubo enengqondo ngokwengeziwe, inqubo futhi inganciphisa ukuvela kokuchitheka komqondo.
