Chena goridhe

The chishongo rinoshandiswa zvikuru zvakawanda zvokunyama. Zvisinei, zviri sechinhu chena chendarama chaiyo. Ring Somuenzaniso, ari simbi, maererano nenyanzvi, anotarisa zvikuru ndarama, kwezvokufuka uye dzemhando yepamusoro kupfuura dzimwe simbi. In America uye Europe kuti zvishongo mu chena goridhe zvino yakawedzerwa kudiwa kuchengetwa.

MuRussia, simbi iyi yakakurumbira kuti vakawanda vachiri chokwadi unhu kwayo, asi vamwe chinhu chaicho chakavanzika. Achigere kuziva 'chena goridhe', kuzvizivisa nayo nesirivha, Platinum kana kuverenga isingawanzowanikwi Zvisaririra. In nyika yedu, simbi iri kure anokunda dzakateyiwa fashoni zvishongo, asi chava kutanga kukwezva pfungwa.

Products dzakagadzirwa nesimbi ichi haruzvitsvakiri vachivhaira, asi zvisingapindirani kwamachinda uye ukuru. Chine muumbozha kungwara, nyasha uye unyanzvi simbi iyi. Iye anogara akakodzera.

White goridhe - zvishongo ane chiwanikwa chendarama uye Platinum, nickel uye palladium. Kuwedzera wakachena chakaipa zviri simbi yaisanganisira zvendarama chiwanikwa yesirivha nemhangura, chiri kushanda kuchinja ruvara rwayo. The chena goridhe sezvo wayo constituent palladium uye nickel simbi shanduko ruvara, akatendeuka kuva chena. The zvakawanda sirivha iri chiwanikwa, ari akachena ruvara inotengwa.

Zvisinei, sirivha anokwanisa batanidza simbi matte, izvo dzimwe nguva hazvisi chinodiwa nokuti akaita zvishongo inofanira kuva chipenye yakachena nendarama tsvuku. Nokuti nzira iyi ra zvishongo rhodium-zvemapuranga. nzira iyi zvinoita kuti simbi Kunogara.

Maererano nenhamba, vanenge 15% vanhu vari sema kuti nickel iri kuchengetwa, iyo kunooneka pacharo uchikurukura resimbi vhiri. Saka zvino EU , mutemo inorambidza kushandisa nickel mune zvishongo. White goridhe, nemurairo, kazhinji havafaniri ane nickel tsvina. Saka, zvinoita kuchatsiviwa palladium, izvo haakonzeri dermatitis. Kunyange zvazvo nickel uye ane chinokosha chinowanika sezvo mukuru chaizvo simba, kubvumira simbi kuti vabudirire kuchisazitasingwi ductility pa nekupa zvitarisiko yakaoma uye yapakuvamba mazano.

Advantageously goridhe chena rinoshandiswa zvaAtemisi kwemangoda kwezvishongo (kazhinji alloys 750) kana dzinongoitika dema parera.

Gold racho yakachena chimiro, pfungwa, harishandiswi zvishongo nokuti nyoro simbi zvakasikwa. Gold zvishongo zvinosanganisira sezvamunoita kwayo kana admixture dzimwe anokosha dzisiri ferrous nesimbi, iyo kumupa simba zvakakodzera, uye tichimukumbira nomumvuri.

Zvakasikwa, pane zvakasikwa chiwanikwa chendarama (16-69%) nesirivha, unonzi yemagetsi (nesirivha). Saka dzimwe nguva unogona kuwana pakunzi ari chiwanikwa uye rokuti "ndarama chena".

Zvishongo zvakagadzirwa nesimbi ichi anonyanya husingakwanisi weathering achienzaniswa nendarama tsvuku. Somuenzaniso, imwe yemuruoko, chena goridhe iro rinoshandiswa senzira huru chesimbi puranga haina kukanganiswa kunyange kakawanda kuonana nemvura. Zviya, chaiyo nokuda chiwanikwa ichi nezvishongo kutarisa kunyanya kunaka, sezvo simbi ane wakanaka plasticity uye rakanakira kugadzira mapango okuvaka dzinodhura dzinongoitika mabwe, zvichiratidza ngachivhenekere dzavo uye kubwinya.

Zvinofungidzirwa kuti chena ghoridhe vakanaka kukunda kwaro tsvuku ishamwari. Zvinofanira kunzwisiswa kuti Precious akatsunga kwete ruvara ake, nokuparara. The yepamusoro zviri, zvikuru iyo chiwanikwa yakaisvonaka. Naizvozvo, kuenzanisa pamusoro chokuratidza kuti kwamachinda chena uye tsvuku nendarama imwe mharidzo hazvina musoro. By "dzisiri vanokudzwa" anoreva alloys zvendarama, umo kunze simbi iyi haibatanidzi zvimwe zvinokosha. Somuenzaniso, sezvo ligatures anoshandiswa chete nickel. Noble chena goridhe anobvisa zvingangoita Kurwara. goridhe kwakadaro zvikuru zvinodhura, ane mhosva kuita uye dzinoyevedza chitarisiko.
