Okuthandwayo kuyashintsha, abanye abantu bajabule futhi abanye abantu badabuke.
UWoodMac ulindele ukuthi ukwakha kabusha ukwethembana kuzothatha isikhathi, futhi amanani okuhweba mancane amathuba okuthi alulame ngokushesha. "Zonke izinkomba zamanani ezimpahla ezithintekayo zizobhekwa kakhulu." Khonamanjalo, i-Fitch Solutions Country Risk and Industry Research ithe njengoba amanani e-nickel enyuka nezindleko zokukhiqiza amabhethri zikhuphuka, abathengi be-nickel yezinga eliphezulu bafuna Izindlela Ezihlukile ezihlinzekwa yiRussia.
I-Russia ingumphakeli ohamba phambili we-Nickel ore yeSigaba 1, kuyilapho i-China ingumdlali obaluleke kakhulu embonini yokucwenga. U-Fitch uthe embikweni wakhe omusha abakhiqizi bezimoto, abakhi bamabhethri nabathengi bezimboni kungenzeka bakhe ubudlelwano obusha bebhizinisi ukuze bathole ezinye izindlela ze-nickel ezisezingeni eliphezulu, njengoba izinto ezivela eRussia zilwa nesizinda sengxabano yaseRussia ne-Ukraine. isavinjelwe. Kuze kube manje, i-China Tsingshan Group kanye nezinye izinkampani ezithuthukisa ngokuqhubekayo umthamo wokucwenga we-nickel wezinga eliphansi zizohlomula.
U-Fitch uphinde waphawula ukuthi ukushintsha okuthandwayo kwabangenisa kwamanye amazwe, unswinyo kanye nesifiso sokunciphisa ubungozi bonswinyo kuthinta ukuthengwa kokuthunyelwa kwe-nickel yaseRussia. Ngakho-ke, imisebenzi yezimayini nokucwengisisa emazweni "aphephile" anemithetho ezinzile kanye nemithetho yohwebo ingase izuze.Njengamanje, i-anodic oxidation ye-titanium ne-titanium alloys yenziwa ikakhulukazi ngesisombululo esimuncu. Umbala, ukujiya kanye nokusebenza kwefilimu ye-oxide etholiwe kuhlukile kuye ngesixazululo se-anodizing kanye nezimo zenqubo.
Izindlela eziyinhloko i-oxalic acid anodizing, i-pulse anodizing, i-anodizing yefilimu ewugqinsi, kanye ne-anodizing yombala. Lapho ifilimu ene-anodized ye-titanium ne-titanium alloys yehluleka ukuhlangabezana nezimfuneko, ihlanganisa nokususwa kwefilimu e-anodized ye-titanium ne-titanium alloys. Okulandelayo yisingeniso se-anodizing enombala:
Umbala we-titanium surface awusebenzi nje kuphela ekukhiqizeni, kodwa futhi unenani elithile lobuciko. Ngaphansi kwezimo ezifanele ze-anodic gasification, ifilimu ye-oxide esobala eyakhiwe phezu kwe-titanium, okulula ukwenza umbala wokuphazamiseka, izokhiqiza umbala ocebile ngenani lobuciko. izicelo ezingaba khona.
Lapho i-current idlula ku-titanium anode emiswe ku-electrolyte, umoya-mpilo okhiqizwe ku-titanium anode usabela ne-titanium ukuze wenze ifilimu ye-oxide, ugqinsi lwalo lukhula ngokunyuka kwe-voltage, futhi ngesikhathi esifanayo, umphumela wokuvimbela. yefilimu ye-oxide kumanje nayo iyanda. . I-voltage ethile ihambisana nogqinsi oluthile lwefilimu ye-oxide, futhi umbala wefilimu ye-oxide ushintsha nobukhulu befilimu ye-oxide.
