Ukhetho luyatshintsha, abanye abantu bonwabile kwaye abanye abantu balusizi.
I-WoodMac ilindele ukuba ukwakha kwakhona ukuthembela kuya kuthatha ixesha, kwaye amanani orhwebo akunakwenzeka ukuba abuyele ngokukhawuleza."Zonke izalathi zamaxabiso eemveliso ezichaphazelekayo ziya kuxhomekeka ekuhlolweni okwandisiweyo."Ngeli xesha, i-Fitch Solutions Country Risk and Industry Research yathi njengoko amaxabiso e-nickel enyuka kunye neendleko zokuvelisa ibhetri zinyuka, abathengi be-nickel yodidi oluphezulu bafuna ezinye iindlela ezibonelelwa yiRashiya.
IRashiya ingoyena mthengisi ohamba phambili woDidi loku-1 lwe-nickel ore, ngelixa iChina ingoyena mdlali ubalulekileyo kushishino lokusulungekisa.UFitch uthe kwingxelo yakhe entsha ukuba abenzi bee-automakers, abenzi beebhetri kunye nabathengi bemizi-mveliso banokuthi benze intsebenziswano entsha yeshishini ukuze bafumane ezinye iindlela zodidi oluphezulu lwe-nickel, njengoko unikezelo oluvela eRussia luzabalaza ngokuchasene nomva wengxabano yaseRussia-Ukraine.isathintelwe.Ukuza kuthi ga ngoku, i-China Tsingshan Group kunye nezinye iinkampani ziphuhlisa umgangatho ophantsi wokusulungekisa i-nickel iya kuzuza.
U-Fitch uphinde waqaphela ukuba ukutshintsha kwezinto ezikhethwa ngabarhwebi, izohlwayo kunye nomnqweno wokunciphisa umngcipheko wezohlwayo kuchaphazela ukuthengwa kwe-nickel yaseRashiya.Ke ngoko, imisebenzi yemigodi kunye nokusulungekiswa kumazwe "akhuselekileyo" anolawulo oluzinzileyo kunye noorhulumente borhwebo banokuzuza.Okwangoku, i-anodic oxidation ye-titanium kunye ne-titanium alloys iqhutyelwa ngokukodwa kwisisombululo se-acidic.Umbala, ubukhulu kunye nokusebenza kwefilimu ye-oxide efunyenweyo iyahluka ngokuxhomekeke kwisisombululo se-anodizing kunye neemeko zenkqubo.
Ezona ndlela ziphambili zi-oxalic acid anodizing, i-pulse anodizing, ifilimu eshinyeneyo enodizing, kunye ne-anodizing yombala.Xa ifilimu ye-anodized ye-titanium kunye ne-titanium alloys ihluleka ukuhlangabezana neemfuno, ibandakanya ukususwa kwefilimu ye-anodized ye-titanium kunye ne-titanium alloys.Oku kulandelayo yintshayelelo ye-anodizing enemibala:
Umbala we-titanium surface awukho luncedo kuphela kwimveliso, kodwa unexabiso elithile lobugcisa.Ngaphantsi kweemeko ezifanelekileyo ze-anodic gasification, ifilimu ye-oxide ecacileyo eyenziwe phezu kwe-titanium, elula ukwenza umbala wokuphazamiseka, iya kuvelisa umbala ocebileyo kwixabiso lobugcisa.izicelo ezinokubakho.
Xa i-current idlula kwi-titanium anode exhonywe kwi-electrolyte, ioksijini eveliswa kwi-titanium anode idibana ne-titanium ukuze yenze ifilimu ye-oxide, ubukhulu bayo bunyuka ngokunyuka kwamandla ombane, kwaye kwangaxeshanye, isiphumo sokuthintela yefilimu ye-oxide kwi-current nayo iyanda..I-voltage ethile ihambelana nobukhulu obuthile befilimu ye-oxide, kwaye umbala wefilimu ye-oxide utshintsha kunye nobukhulu befilimu ye-oxide.
