Kuda kunoshanduka, vamwe vanhu vanofara uye vamwe vanhu vakasuwa.
WoodMac inotarisira kuti kuvakazve kuvimba kunotora nguva, uye mavhoriyamu ekutengesa haafanire kupora nekukurumidza."Maindice ese emitengo yezvinhu zvakakanganiswa achaongororwa zvakanyanya."Zvichakadaro, Fitch Solutions Country Risk uye Indasitiri Research yakati sezvo mitengo yenickel inokwira uye mutengo wekugadzira mabhatiri uchikwira, vatengi vepamusoro-giredhi nickel vanotsvaga maAlternatives anopihwa neRussia.
Russia ndiyo inotungamira mutengesi weChikamu 1 nickel ore, nepo China iriyo mutambi akakosha muindasitiri yekukwenenzvera.Fitch akadaro mumushumo wake mutsva kuti vagadziri vemotokari, vagadziri vemabhatiri uye vatengi vemumaindasitiri vanogona kugadzira hukama hutsva hwebhizinesi kuti vaunze dzimwe nzira dzepamusoro-giredhi nickel, sezvo zvinhu kubva kuRussia zvichinetsana nekumashure kwekunetsana kweRussia-Ukraine.zvichiri kurambidzwa.Kuti izvi zviitike, China Tsingshan Group nemamwe makambani anoshingairira kugadzira yakaderera-giredhi nickel refining inozobatsira.
Fitch akacherekedzawo kuti kushandura zvinodiwa nevanopinda kunze kwenyika, zvirango uye chishuwo chekudzikisa njodzi yezvirango zviri kukanganisa kutenga kweRussia nickel inotengeswa kunze kwenyika.Naizvozvo, migodhi nekunatsa mashandiro munyika "dzakachengeteka" dzine hutongi hwakagadzikana uye hutongi hwekutengeserana hunogona kubatsirwa.Parizvino, iyo anodic oxidation yetitanium uye titanium alloys inonyanya kuitwa mune acidic mhinduro.Ruvara, ukobvu uye kuita kweiyo yakawanikwa oxide firimu zvakasiyana zvichienderana neanodizing mhinduro uye maitiro ekugadzirisa.
Nzira huru ndeye oxalic acid anodizing, pulse anodizing, gobvu firimu anodizing, uye ruvara anodizing.Kana iyo anodized firimu yetitanium uye titanium alloys inotadza kuzadzisa zvinodiwa, inosanganisirawo kubviswa kweanodized firimu retitanium uye titanium alloys.Izvi zvinotevera sumo kune ane mavara anodizing:
Rudzi rwetitanium pamusoro harubatsiri chete mukugadzirwa, asi zvakare rine humwe hunyanzvi kukosha.Pasi pemamiriro akakodzera eanodic gasification, iyo yakajeka oxide firimu yakaumbwa pamusoro petitanium, iri nyore kugadzira ruvara rwekukanganisa, inoburitsa ruvara rwakapfuma mukukosha kwehunyanzvi.zvinogona kushandiswa.
Kana iyo yazvino ichipfuura nepakati petitanium anode yakamiswa mu electrolyte, iyo okisijeni inogadzirwa patitanium anode inopindirana netitanium kuumba oxide firimu, ukobvu hwayo hunowedzera nekuwedzera kwevoltage, uye panguva imwe chete, kukanganisa mhedzisiro. yeiyo oxide firimu pane yazvino inowedzerawo..Imwe magetsi inoenderana nehumwe ukobvu hweiyo oxide firimu, uye ruvara rweiyo oxide firimu inoshanduka nekukora kweiyo oxide firimu.
