Mkpuchi

TEHRAN, 31 August (MNA) - Ndị na-eme nchọpụta sitere na Mahadum Sayensị na Nkà na Ụzụ MSiS (NUST MASIS) ewepụtala usoro pụrụ iche maka itinye mkpuchi mkpuchi na ihe ndị dị mkpa na akụkụ nke teknụzụ ọgbara ọhụrụ.
Ndị ọkà mmụta sayensị sitere na Mahadum Rọshịa MISIS (NUST MISIS) na-ekwu na mmalite nke nkà na ụzụ ha dabeere na ijikọta uru nke ụzọ nkwụnye ego atọ dabere n'ụkpụrụ anụ ahụ dị iche iche n'otu usoro ikuku. Site n'itinye ụzọ ndị a, ha nwetara mkpuchi mkpuchi multi-layer na oke okpomọkụ na-eguzogide, na-eyi nkwụsi ike na nkwụsị nke corrosion, Sputnik na-akọ.
Dị ka ndị na-eme nchọpụta si kwuo, nhazi mbụ nke mkpuchi nke na-esi na ya pụta mere ka ọganihu 1.5 na-eme ka ọ dịkwuo mma na nkwụsị nke corrosion na okpomọkụ dị elu ma e jiri ya tụnyere ngwọta ndị dị ugbu a. E bipụtara nsonaazụ ha na International Journal of Ceramics.
"N'ihi na oge mbụ, a na-enweta ihe mkpuchi nchebe nke electrode dabere na chromium carbide na onye na-ekekọta NiAl (Cr3C2-NiAl) site na mmejuputa mmejuputa atumatu electrospark alloying (VES), pulsed cathode-arc evaporation (IPCAE) na magnetron sputtering.

Dị ka ya si kwuo, ha buru ụzọ mesoo elu na VESA iji nyefee ihe sitere na Cr3C2-NiAl ceramic electrode na mkpụrụ, na-eme ka ike dị elu dị n'etiti mkpuchi na ihe mkpuchi.
N'oge na-esote, n'oge pulsed cathode-arc evaporation (PCIA), ions sitere na cathode na-ejuputa ntụpọ na oyi akwa nke mbụ, na-agbaji mgbawa ma na-akpụ akwa akwa na akwa akwa nke nwere nnukwu nguzogide corrosion.
