375 mufananidzo wegoridhe

Ndarama ndiyo chete yakasungirirwa pasi pano ine mavara akanaka akachena ruvara rwechimiro chayo isina kuwedzera. Nzvimbo yegoridhe yakasviba ine ruzivo rwakanaka, iyo inowedzera zvikuru nekugadzira. Kazhinji goridhe inowanikwa nekugadzirwa kwezvisikwa zvepanyama kana kupfuura panguva yekuchera migodhi zvimwe zvigadzirwa kubva kune ores. Nzvimbo yegoridhe chaiyo kazhinji haina kuchena, ine mhangura uye sirivha sekusvibiswa kwayo kukuru, uye zvimwe zvinhu zvinowanikwa zvinowanikwa sezvisina kuwedzerwa zvimwe. Nokudaro, kuitira kuchenesa, goridhe inotungamirirwa nehuwandu hwekugadzira (kuchenesa) pamabhizimisi emigodhi emigodhi.

Henderedhi yegoridhe yakatove yakagadzirwa mukucheneswa kwe 99.99% nenzira ye ingots, firi, chidimbu, zvipfeko, ribhoni uye zvimwe zvigadzirwa zvemiviri. Mune chimiro iyi inonyoro uye ductile metal, somuenzaniso, kubva pagiramu imwe yesimbi yakadaro inogona kukwevera tambo makiromita matatu nehafu pakureba. Muchengetedzi yezvishongo, ndarama yasati yatoshandiswa nenzira yezvinyorwa zvakasiyana-siyana kuita zvishongo. Zvose izvi zvinyorwa zvine zvimwe zvigadzirwa zvegoridhe uye, maererano neizvi, zvinopiwa samples. Izvo zvakaderera zvakagadzirwa nesimbi yakakosha ine 375 yegoridhe samples.

Alloys yemuenzaniso uyu ane mukugadzirwa kwawo chete 37.5% yegoridhe rakachena, izvo zvinosara zvikamu zvendarira nesirivha. Nyanzvi dzemhizha yezvishongo dzimwe nguva dzinofanidzawo kuti ine ndarama ine zendarira nesirivha. Maererano nemitemo yeRussia, pane mazita mashanu earloys ayo mashandisirwo 375 egoridhe anoshandiswa. Zvose izvi zvinokonzera kupera mumhepo yakapoteredza, saka iyo pfuma inogadzirisa zviyero zvekushandisa kwavo. Zvose zvakasiyana-siyana zvemavara aya anowanikwa kubva kune tsvuku kusvika kune tsvuku, asi kakawanda inowirirana zvikuru pamwe nealloy ye 585 samples yezvinonzi "samovar" yegoridhe yemavara mutsvuku. Alloys iyo idhinha ndiyo yakasimba zvikuru uye yakaoma zvikuru, iyo yakakodzerwa yekugadzirisa.

Pasinei nokuti iyi ndiyo yegoridhe yepamusoro, inowana kushanda mumhizha yezvishongo. Kazhinji, aya alloys anoshandiswa mukugadzira zvindori zvekuita. MuRussian Federation, maererano nehuwandu, hapana huri pasi-alloy, asi munyika dzeEurope, 333 ndarama inoshandiswa, iyo inoshandiswawo pakugadzira zvishongo nezvishongo. Ndarama dzezvikamu zvakasiyana-siyana dzinonyanya kushandiswa mumhizha yezvishongo, nokuti kana ichiwedzera mitambo yakasiyana-siyana kwavari, mavara akasiyana anokwanisa kuwanikwa: tsvuku, dhizha, yeguru uye kunyange yakachena, pamwe chete nemhando yakawanda yemashizha.

Kazhinji nokuda kwekugadzirwa kwezvishongo zvinoshandiswa nemaarloys, zvinosanganisira zvikamu zvakawanda. Kana iyo saridhe ye 375 inowanikwa zvikurukuru nekuwedzera mhangura uye sirivha kune gorosi, mumasasa akasara, palladium, platinum, zinc, cadmium uye nickel zvinoshandiswa seguriti. Chimwe nechimwe chikamu chinokwanisa kupa rumwe rutivi rwemajeri. Sirivha inogadzira gorofu yegoridhe yakawanda isingasviki uye ipurasitiki uye iri nyore. Kuwedzerwa kwemhangura kunowedzera kuoma kweiyo, asi inopesana nemarara inowedzera. Uyewo, jira rakadaro rinowedzera mumvuri wakatsvuka.

Kuwedzerwa kwe cadmium kunoita kuti gorosi rive fusible uye rinowanzoshandiswa segorodi ine ndarama. Izvo zvakafanana zvinowanikwa kune zinc, nekuwedzera, zvinopenya gorosi, izvo zvinoita kuti zvikwanise kuzvishandisa mukugadzirwa kwegoridhe chena. Siriro yakadai inodhura seplatinum uye palladium inopa zvirovhe zvegoridhe plastiki, kutengesa uye zvinovhenekera. Mukuwedzera, vanovapa yakasimba anti-corrosion properties. Zvisinei, 375 zvigadzirwa zvegoridhe hazviitike nekuwedzera kwezvinhu izvi zvesimbi. Izvo zvikamu zvikuru zvayo ndeyendarama, sirivha nemhangura.
