Pane imwe 925 goridhe

Ndarama alloys GOST kuisa zvimwe kusanganiswa ukoshi - bvunzo iyi, izvo zvinogona kuona uwandu zvidimbu anokosha simbi iri muzvikamu 1000 zvendarama chiwanikwa. Saka, muna Russian Federation pamutemo 925 goridhe vasipo. At forum siyana zvishongo kazhinji akakurukura mubvunzo: "Pane imwe 925 goridhe?" Dzimwe nguva iwoyo kunogona akawana mhinduro: ". Ndicho chena goridhe" Chokwadi, chena ndarama chiwanikwa ndiye anokudzwa simbi nomumwe simbi chena: manganese, nickel kana palladium.

Dzakagadzirirwa chena goridhe yaiva 1920 uye zvino zvava mufashoni chaizvo zvinhu zvakasiyana-siyana zvishongo makambani kuti asike ounyanzvi dzavo pazviri. Saka, zvinhu izvi zvava akakurumbira pakati connoisseurs wakaisvonaka zvishongo. Shoko rokuti "chena" zvinoreva kumbonyanya siyana noruvara kubva zvisvundu akacheneruka kuti hapana tsvuku, unogona kuuya kuyambuka pingi rakachenuruka. Dzimwe ari zvishongo indasitiri kuwana zvachose chena pamusoro, achishandisa unhani pamusoro rhodium, izvo kunokosha zvikuru kupfuura ndarama. bemhapemha Izvi zvinopa chigadzirwa yakajeka chipenye, kunowedzera kwavo neukukutu uye vanopfeka nemishonga, achidzivirira kubva anokwenya uye kukuvadza.

Kuti vawane chena-ruvara goridhe chiwanikwa simbi rinowanzoshandiswa Kuwedzera nayo palladium. Kunyange mamwe mavara kwazvo chena Kuwedzera Platinum chiwanikwa. In embodiments dzakawanda kushandisa zvakachipa kuwedzera nickel. Zvisinei, vanachiremba yakasimbiswa kuti pane sema kune nickel mumwe munhu kubva sere, saka muna 2000 European kunyika iri zvishongo chakagadzirwa chena goridhe nickel yakawedzerwa hakubvumidzwi. Properties michena alloys goridhe zvakasiyana zvichienderana kukura uye mhando akawedzera kuti chiwanikwa chainge chakagadzirwa nesimbi, zvisinei, 925 nendarama Russia haina rakapa, sezvo vose zvishongo zvegoridhe, zvisinei ruvara dzavo, maererano mitemo vanogona chete kuva 375, 583, 585, 750 uye 958 ivhu.

925 ndicho sirivha mharidzo. Kare, pamberi nokugadzirwa kwakaitwa chena sirivha nendarama rinowanzoshandiswa kugadzirwa wedhaimondi zvishongo semagada kunoratidza kupfuura kubudirira anokosha aya chipenye uye pave wokuwedzera mugumisiro okuvimba. Zvadaro, mangoda vakanga kuiswa mune zvivezwa chena goridhe sechinhu chiwanikwa zvendarama palladium kazhinji mupurasitiki munyoro, saka zviri kunyanya zvakanaka embed mairi matombo anokosha. Zvisinei, pane harishandiswi 925 goridhe, uye rakajairika 750. Izvi chiwanikwa ternary, sezvo kazhinji chinayo kupfuura goridhe nesirivha nemhangura (dzimwe nguva zingi, nickel uye palladium), zvinogona namavara akasiyana - kubva yakatsvukuruka kusvikira chena.

Kunze kwake, zvikuru zvikuru kuparadzira goridhe chiwanikwa 585. Murwiyo ndarama 585 vari yemanyorero-nzira nhatu, ayo ruvara anewo zvakawanda mavara akasiyana, zvichienderana vakashandisa ligature - kubva tsvuku kusvikira chena. Zvichienderana ayo sezvamunoita, unogona kuva zvakasiyana kwoukukutu uye zvakasiyana utsotso kutonhora, kazhinji akadaro chiwanikwa iri chaizvo anoonawo zvakanaka zvokudya. Yakaderera yokuenzanisira 375 yemanyorero ane zvishoma muted yakatsvukuruka ruvara uye anova pfumbu inzwi nokurasikirwa pakuonekwa.

The soro yokuenzanisira ndarama - ane chiwanikwa kubva 958 nemiedzo, naiyewo ternary chiwanikwa pamwe kuwedzera sirivha nendarama nemhangura. Nokuda mukuru zviri zvendarama zviri kwazvo nyoro uye saka anobudiswa zvishongo kubva chiwanikwa makorari anoiteerera refu. Kazhinji ane zvakanaka dzakapfavirira rakajeka tsvuku ruvara, riri pedyo ruvara yakaisvonaka, uye kunyanya kushandiswa kugadzirwa muchato zvindori.
