Ingaba ikhona igolide 925

Kuba zegolide aluminiyamu GOST ukubeka ixabiso ethile kwamanani - olu vavanyo, nto leyo ukufumanisa inani ngentsimbi anqabileyo iqulethwe 1000 iindawo ingxubevange yegolide. Ngoko, kwi Russian Federation ngokusemthethweni 925 igolide khona. "Ingaba ikhona igolide 925?" Maxa wambi lo mbuzo anokufunyanwa impendulo: iintlobo ntlobo zeeforamu izacholo rhoqo umbuzo kuxoxwa ". Yinto igolide white" Eneneni, ingxubevange igolide Elimhlophe kwensimbi amanene kunye nenye white metal: manganese, nickel okanye palladium.

Lo Endliwa igolide white waba ngo-1920 yaye ngoku sele izinto nendlela kakhulu ngenxa yezizathu ezininzi ezahlukeneyo kwiinkampani izacholo ukuba yobuciko zabo kulo. Ngoko ke, ezi mveliso baba ethandwa ngakumbi phakathi iingcali ubucwebe entle. Igama elithi "emhlophe" ithetha uluhlu olubanzi ngokufanelekileyo nombala omdaka sakuba ukuba lisuke labuna tyheli, unako nokuba uhlangabezana sakuba. Ngamanye amaxesha kushishino izacholo ukuze ufumane kumphezulu emhlophe ngokupheleleyo, usebenzisa ukutyabeka of rhodium, nto leyo oluxabiseke ngaphezu kwegolide. Olu daka kunika imveliso kukhanya eqaqambileyo, kwandisa yokuqaqadeka banxibe ukuxhathisa, ukukhusela kusuka yimikrwelo kunye nomonakalo.

Ukuze ufumane emhlophe-umbala ingxubevange gold steel isoloko isetyenziswa ukongeza kuyo palladium. imibala zamhlophe qhwa ukongeza platinum ingxubevange ngakumbi. In embodiments ezininzi usebenzisa ukudibanisa cheap nickel. Noko ke, oogqirha yasekwa ukuba kukho umzimba nickel umntu omnye aphume ezisibhozo, ngoko ke ngowe-2000, kumazwe aseYurophu kwi izacholo ezenziwe nickel ezimhlophe added igolide akuvumelekanga. Iimpawu aluminiyamu zegolide white zahlukile ngokuxhomekeke olinganise kunye neendidi kongezelelwa ingxubevange zesinyithi, nakuba kunjalo, 925 zegolide eRashiya asinikezwanga, ekubeni zonke zegolide, nokuba ibala lazo, ngokwemigangatho emiselwe unokuba kuphela 375, 583, 585, 750 no 958 iisampuli.

925 yeyona ixhaphakileyo isampuli yesilivere. Ngaphambili, ngaphambi kokuba kusungulwe isilivere negolide white isoloko isetyenziswa ukuba ukwenziwa diamond izacholo, njengoko emhlophe ibonisa iyimpumelelo la magugu kukhanye kwaye kudala isiphumo eyongezelelweyo ukukhanyisa. Kamva, le ngedayimani zithe zafakelwa kwiimveliso zegolide white njengento intsila zegolide palladium zikholisa zeplastiki ethambileyo, ngoko kuhle ngakumbi ukuba kuzakulungisa kuyo amatye. Nangona kunjalo, akukho nto kusetyenziswa 925 negolide, kwaye ixhaphakileyo 750. Le ingxubevange izithathu, ekubeni ngokuqhelekileyo ifaka ngaphezu kwegolide kunye nobhedu nesilivere (ngamanye amaxesha nezinki, nickel kunye palladium), kunokuba imibala eyahlukileyo - ukusuka kwayingqombela mhlophe.

Ngaphandle kuye, kakhulu yanwenwa ingxubevange igolide 585. Ukubunjwa zegolide 585 nayo njenge ndlela ezintathu-, umbala wayo une uluhlu olubanzi imibala ezahlukeneyo, ngokuxhomekeke ligature isicelo - obomvu emhlophe. Ngokuxhomekeka ukwakheka yayo, oko unokuba ngokuba lukhuni ezahlukeneyo kwawe ezahlukeneyo, idla intsila eso kakhulu iphendula kakuhle ukuba yokudla. isampuli Osezantsi 375 ayidli sayingqombela umbala umsindo kancinane lube isandi amdaka kunye nelahleko wokucoca.

Isampulu ephezulu zegolide - i intsila yeemvavanyo 958, yena ingxubevange kwakhona izithathu kongezwe isilivere negolide nobhedu. Ngenxa eninzi yegolide ngayo ithambe kakhulu kwaye ngoko eziveliswa izivatho ukusuka wokucoca ingxubevange ubagcina elide. Kuvamise soft nice umbala otyheli eqaqambileyo, leyo ikufuphi yimbonakalo yegolide ecocekileyo, kwaye ubukhulu becala kusetyenziswa ekwenziweni amakhonkco yomtshato.
