1. Izinto ezithuthukisiwe zegolide: Kuthatha usilika osagolide njengesisekelo, futhi ubuso bawo bumbozwe ungqimba lwegolide elivulekile (K).Kunemibala emibili yegolide elivulekile: igolide elimhlophe negolide eliphuzi.
A. igolide
Lena insimbi esagolide ene-ductility enhle futhi cishe ayinakho ukushintsha kombala kwe-oxidative.Njengoba igolide elimsulwa (24K) lithambile kakhulu, uma usebenzisa igolide njengohlaka lombukwane.Ixubene nezithasiselo ezifana nensimbi nesiliva ukuze iyenze ibe ingxubevange ukunciphisa izinga nokwandisa amandla nokuqina.Okuqukethwe kwegolide kozimele bezibuko ngokuvamile kungu-18K, 14K, 12K, loK.
B iplatinum
Lena insimbi emhlophe, esindayo futhi ebizayo, enobumsulwa obungama-95%.
2. Vula igolide bese ufaka igolide
A. Liyini igolide elivulekile?Okubizwa ngokuthi (K) igolide akulona igolide elihlanzekile, kodwa ingxubevange eyenziwe ngegolide elicwengekileyo nezinye izinsimbi.Igolide elimsulwa igolide elingakahlanganiswa ngokugcwele (okungukuthi, alifakwanga kwezinye izinsimbi).Igolide elivuliwe elisetshenziswa ebhizinisini libhekisela esilinganisweni segolide elimsulwa nezinye izinsimbi kungxubevange, evezwe ngezinombolo (K), evezwa njengokuphindaphinda kokukodwa kokune kwesamba sesisindo segolide, ngakho-ke igolide elingu-24K liyigolide elimsulwa. .Igolide elingu-12K ingxubevange equkethe izingxenye eziyishumi nambili zegolide elicwengekileyo kanye nezingxenye eziyishumi nambili zezinye izinsimbi, futhi igolide elingu-9K ingxubevange equkethe izingxenye eziyisishiyagalolunye zegolide elicwengekileyo kanye nezingxenye eziyishumi nanhlanu zezinye izinsimbi.
B. Gild
Ukugqokwa kwegolide kusho ikhwalithi.Ekwenziweni kwegolide, ungqimba olulodwa lwesisekelo sensimbi luhlanganiswe nongqimba olulodwa lwegolide elivulekile, futhi ukucaciswa kwezinto zokugcina kuyinani legolide elivulekile elisetshenzisiwe kanye nenani legolide elivulekile.
Kunezindlela ezimbili zokuveza ukunameka kwegolide: ingxenye yeshumi ye-12 (K) isho ukuthi ingxenye eyishumi yesisindo sohlaka iyigolide elingu-12K;enye ivezwa inani legolide elihlanzekile eliqukethwe emkhiqizweni osuphelile;ingxenye yeshumi yegolide engu-12K ingabhalwa njengegolide elihlanzekile elingu-5/100 (ngoba igolide elingu-12K liqukethe igolide elimsulwa elingu-50/100).Ngokufanayo, igolide elingu-10K lamashumi amabili nanye lingabhalwa njengegolide elihlanzekile elingu-21/looo.Ngokufanisa, kokubili igolide eliphuzi nelimhlophe kungasetshenziswa ukwenza amafreyimu anegolide.
3. I-Copper alloy material
Ama-alloys ethusi abaluleke kakhulu ithusi, ithusi, i-zinc cupronickel, njll., kanye nethusi ne-curonickel avame ukusetshenziswa embonini yezibuko.
A. Ingxubevange ye-nickel ye-zinc (i-zinc cupronickel)
Ngenxa yemishini yayo emihle (i-machinability, i-electroplating, njll.), ingasetshenziswa kuzo zonke izingxenye.I-ternary alloy equkethe i-Cu64, Ni18, ne-Znl8.
B. Ithusi
I-alloy kanambambili equkethe i-cu63-65% kanti enye i-zn, enombala ophuzi.Okubi ukuthi kulula ukushintsha umbala, kodwa ngenxa yokuthi i-chip kulula ukuyicubungula, ingasetshenziswa ukwenza ama-pads ekhaleni.
C. Copper nickel zinc tin alloy (Bran Kas)
Kule alloy ye-quaternary equkethe i-Cu62, i-Ni23, i-zn1 3, ne-Sn2, ingasetshenziselwa usilika onqenqemeni kanye nezimpawu ezimise okwefektri ngenxa yokunwebeka kwayo okuhle kakhulu, izakhiwo ze-electroplating kanye nokumelana nokugqwala okuhle kakhulu.
D. Ibhulonzi
Lena ingxubevange ye-Cu kanye ne-sn alloys enezakhiwo ezahlukene ngokuya ngenani le-sn eliqukethwe.Uma kuqhathaniswa nethusi, ngoba iqukethe i-tin sn, iyabiza futhi inzima kakhulu ukuyicubungula, kodwa ngenxa yokunwebeka kwayo okuhle kakhulu, ifaneleka ezintweni zocingo olusemaphethelweni, kanti okubi ukuthi ayimelani nokugqwala.
E. Ingxubevange ye-nickel-copper yamandla aphezulu ukumelana nokugqwala
Lena ingxubevange equkethe i-Ni67, CU28, Fc2Mnl, ne-5i.Umbala umnyama nomhlophe, unamandla okumelana nokugqwala kanye nokunwebeka okungekuhle.Ifanele indandatho yohlaka.
Cishe wonke ama-alloys ethusi amahlanu angenhla angasetshenziswa njenge-primer yezinto zokwakha zegolide kanye ne-primer ye-electroplating kumafreyimu we-spectacle akhiqizwa ekhaya naphesheya.
4.Insimbi Engagqwali
Lena ingxubevange equkethe i-Fe, Cr, ne-Ni.Ukumelana nokugqwala okuhle, okunezici ezihlukile ezinezithasiselo ezahlukahlukene.I-elasticity ephezulu, esetshenziswa njengamathempeli nezikulufu.
5. Isiliva
Amafreyimu amadala kakhulu enziwe nge-alloy yesiliva.Izingilazi zakwamanye amazwe ezinezibambo ezinde kuphela nezinye izingilazi zokunamathisela ezinamathiselwe zokuhlobisa ezisasetshenziswa njengezinto zokusetshenziswa zanamuhla.
6. I-Aluminiyamu ene-anodized
Impahla ilula, imelana nokugqwala, futhi ungqimba lwangaphandle lwe-alumina lungakhuphula ubulukhuni bento.Futhi ingadaywa ngemibala ehlukahlukene edonsa amehlo.
7. I-nickel yesiliva
Umnyango wethusi ne-nickel alloy, bese wengeza i-zinc bleaching.Kwenza ukubonakala kube isiliva, ngakho-ke kubizwa nangokuthi "isiliva langaphandle".Iqinile, imelana nokugqwala, futhi ishibhile kunengubo yegolide.Ngakho-ke, ingasetshenziswa njengohlaka lwengane.Ngemva kokwenziwa kohlaka, i-nickel plating ehlanzekile isetshenziswa ukwenza ukubukeka kukhanye.
8.Titanium (Ti)
Lena insimbi enesisindo esilula, ekwazi ukumelana nokushisa, futhi imelana nokugqwala esidonse ukunaka kwezimboni ezihlukahlukene.Okubi ukuthi kunezici eziningi ezithinta ukungazinzi kwendawo eyenziwe ngomshini.
9. I-Rhodium Plating
I-Electroplating rhodium kufreyimu yegolide ephuzi, umkhiqizo oqediwe uwuhlaka olumhlophe lwegolide okungezona ezensimbi nezinto zokwenziwa ezisebenza ngokuzinzile nokubukeka okwanelisayo.
