Iplati yeNickel eqaqambileyo ye-1149 Barrel

▪ Le nkqubo ibonisa amandla angaqhelekanga okuphosa, iqinisekisa ukufakwa okufanayo nakwiijiyometri ezintsonkothileyo nakwiindawo ezinzulu. Uzinzo lokuhlamba lugcinwa ixesha elide, kunye nokubola okuncinci kwezongezo zendalo, okuncedisa kumgangatho ohambelanayo wokugquma. Ukwakheka kwe-electrolyte kubandakanya izikhanyisi ezikhethekileyo kunye neearhente zokulinganisa eziphucula amandla okuphosa amancinci, nto leyo ekhokelela ekugqityweni komphezulu ogudileyo nokhanyayo.

▪ Le nkqubo iyahambelana nolwakhiwo lwe-rack kunye ne-barrel plating, inika ukuguquguquka ekuphatheni ubungakanani kunye nomthamo wezinto zokusebenza ezahlukeneyo. Ibhafu isebenza ngokufanelekileyo ngaphakathi koluhlu olubanzi lobushushu, oluqhele ukuba phakathi kwama-45°C ukuya kuma-65°C, olunokulungiswa ngokusekelwe kwiimfuno ezithile zokusetyenziswa. Inqanaba le-pH lilawulwa ngononophelo ngaphakathi koluhlu oluncinci, oluqhele ukuba phakathi kwama-3.8 ukuya kuma-4.5, ukuze kuphuculwe amazinga okufakwa kunye neempawu zokugquma.

▪ Uxinzelelo lwee-ion ze-nickel kwisisombululo seplating lugcinwa ngaphakathi kwe-70 ukuya kwi-90 g/L, ngelixa ii-ion ze-chloride zigcinwa phakathi kwe-10 ukuya kwi-20 g/L ukuqinisekisa ukubola kwe-anode kunye nokuqhuba kakuhle. Ukusetyenziswa kwee-anode ze-nickel ezicocekileyo kakhulu, ezidityaniswe neengxowa ze-anode, kunciphisa ukungena kokungcola kunye nezinto ezincinci ebhafini.

▪ Le nkqubo ibandakanya iinkqubo zokucoca eziphambili, ezidla ngokusebenzisa iikhatriji zesihluzo ze-micron ezi-5 ukuya kwezili-10, ukususa naziphi na izinto eziqinileyo ezixhonyiweyo kunye nokugcina ukucaca kwebhafu. Uvavanyo oluqhelekileyo lwe-Hull cell lwenziwa ukujonga ukusebenza kwebhafu kunye nokulungisa uxinano lwezongezo njengoko kufuneka. Ukuguquguquka komaleko we-nickel egciniweyo kudla ngokudlula i-8%, njengoko kulinganiswa luvavanyo lwe-spiral contractometer, ukuqinisekisa ukusebenza okugqwesileyo kwimisebenzi yokwenza emva kweplati.

▪ Ubunzima bengubo bunokulungiswa phakathi kwe-250 ukuya kwi-450 HV ngokulungelelanisa iiparamitha zokuhlamba kunye neereyithingi zokongeza, nto leyo eyenza ifaneleke kwiindlela ezahlukeneyo zokusebenza kwezoshishino. Le nkqubo ibonisa iimpawu zokunamathela ezibalaseleyo, kunye novavanyo lwamandla exolo oluhlala ludlula i-8 N/mm². Ukumelana nokugqwala kwediphozithi ye-nickel, njengoko kuhlolwe luvavanyo lwe-salt spray, kudla ngokudlula iiyure ezingama-96 ukuya kugqwala okumhlophe kunye neeyure ezingama-200 ukuya kugqwala okubomvu xa kutywinwe ngokufanelekileyo.

▪ Amandla angaqhelekanga okuphosa i-macro-throw ebhafini, adla ngokudlula i-80% njengoko ilinganiswe yiseli yeHaring-Blum, aqinisekisa ukusasazwa kobukhulu obufanayo be-coating. Le nkqubo isebenza ngokukodwa kwiindawo ezinomlinganiselo ophezulu, kunye nokuguquguquka kobukhulu okuhlala kungaphantsi kwe-15% kuyo yonke indawo yokusebenza. Uxinzelelo oluphantsi lwangaphakathi lwediphozithi, oluhlala lungaphantsi kwe-10 MPa njengoko ilinganiswe yi-spiral contractometer, lunciphisa umngcipheko wokuqhekeka okanye ukwahlukana.

▪ Le nkqubo ibandakanya iinkqubo zokubeka esweni ngexesha langempela kwiiparameter ezibalulekileyo ezifana nobushushu, i-pH, kunye noxinzelelo lwesinyithi, ukuqinisekisa umgangatho ohambelanayo wokugquma. Ukusetyenziswa kwezongezo zendalo eziphucukileyo ezineempawu ezizilawulayo kuncedisa kubomi obude bokuhlamba, obuhlala budlula i-12 MTO (i-metal turnovers) ngaphandle kokuwohloka okukhulu komgangatho wokugquma. Le nkqubo yenzelwe ukuhlangabezana nemigangatho eqinileyo yoshishino, kubandakanya i-ASTM B689 kunye ne-ISO 1456 ye-electroposited nickel coatings.
