Doorashadu way is beddeshaa, dadka qaar way faraxsan yihiin, qaarna way murugaysan yihiin.
WoodMac waxay rajaynaysaa in dib-u-dhiska kalsoonida ay qaadan doonto wakhti, iyo mugga ganacsigu uma badna inay isla markiiba soo kabtaan."Dhammaan tusmooyinka qiimaha ee badeecadaha ay saameeyeen waxa lagu kordhin doonaa baaris."Dhanka kale, Fitch Solutions Country Khatarta iyo Cilmi-baarista Warshadaha ayaa sheegtay in iyadoo qiimaha nikkelku uu sare u kaco iyo qiimaha wax soo saarka batteriga uu sare u kaco, macaamiisha darajada sare ee nikkel-ka waxay raadiyaan Ikhtiyaarada uu keeno Ruushka.
Ruushka ayaa hormuud u ah alaab-qeybiyaha qeybta 1-aad ee macdanta nikkel-ka, halka Shiinuhu uu yahay kan ugu muhiimsan warshadaha sifeynta.Fitch waxay ku sheegtay warbixinteeda cusub in baabuurta, kuwa batteriga sameeya iyo macaamiisha warshadaha ay u badan tahay inay abuuraan iskaashi ganacsi oo cusub si ay u helaan beddelaad heer sare ah oo nikkel ah, iyadoo sahayda ka timaadda Ruushka ay la halgamayso dib-u-dhacii khilaafka Ruushka iyo Ukraine.weli xaddidan.Si taas loo gaaro, China Tsingshan Group iyo shirkado kale oo si firfircoon u kobcinaya awoodda sifeynta nikkel-hoose ayaa ka faa'iideysan doona.
Fitch ayaa sidoo kale xustay in beddelka dookhyada soo dejinta, cunaqabataynta iyo rabitaanka in la yareeyo khatarta cunaqabataynta ay saamaynayso iibsashada nikkelka Ruushka ee dhoofinta.Sidaa darteed, hawlgallada macdan qodista iyo sifaynta ee dalalka "nabdoon" ee leh nidaamyo sharciyeed iyo ganacsi oo xasilloon ayaa laga yaabaa inay ka faa'iidaystaan.Waqtigan xaadirka ah, oksaydhka anodic ee titanium iyo titanium alloys waxaa inta badan lagu fuliyaa xal acidic ah.Midabka, dhumucda iyo waxqabadka filimka oksaydhka ee la helay way ka duwan yihiin iyadoo ku xiran xalalka anodizing iyo xaaladaha habka.
Hababka ugu muhiimsan waa anodizing oxalic acid, anodizing garaaca wadnaha, anodizing film qaro weyn, iyo anodizing midabka.Marka filimka anodized ee titanium iyo titanium alloys ay ku guuldareystaan inay buuxiyaan shuruudaha, waxay sidoo kale ku lug leedahay ka saarida filimka anodized ee titanium iyo titanium alloys.Kuwa soo socdaa waa hordhac anodizing midab leh:
Midabka dusha titanium ma aha oo kaliya faa'iido u leh wax soo saarka, laakiin sidoo kale wuxuu leeyahay qiimo farshaxan oo gaar ah.Marka la eego xaaladaha gaasta saxda ah ee anodic, filimka oxide ee hufan ee laga sameeyay dusha sare ee titanium, taas oo sahlan in la sameeyo midabka faragelinta, waxay soo saari doontaa midab hodan ku ah qiimaha farshaxanka.codsiyada iman kara.
Marka hadda uu dhex maro anode titanium oo ku xayiran electrolyte, oksijiinta ka soo baxda titanium anode waxay la falgashaa titanium si ay u sameyso filim oxide ah, dhumucdiisuna waxay kordhisaa kororka tamarta, isla markaana, saameynta xannibaadda. Filimka oksaydhka ee hadda jira ayaa sidoo kale kor u kaca..Qayb gaar ah waxay u dhigantaa dhumuc gaar ah oo filimka oksaydhka ah, iyo midabka filimka oksaydhku wuxuu isbeddelaa dhumucda filimka oksaydhka.
