Ni izihe nyungu zo gukoresha Nickel - zishingiye kuri Alloys?

Imikorere ihanitse, irwanya ruswa, hamwe nubushyuhe bwo hejuru, ikora ibidukikije byizewe kandi bikora neza, bituma iba "umwami wibintu" mubidukikije bikabije.

Nickel - ibivanze (nka Inconel, Hastelloy, Monel, nibindi) bikoreshwa cyane mu nganda nka peteroli, imiti, n’ingufu bitewe n’imiterere yihariye, birwanya ruswa, hamwe n’ubushyuhe bukabije -, bifasha kugera ku bikorwa byiza kandi byiza. Bagaragaza imikorere idasanzwe mubidukikije bikabije nkubushyuhe bwo hejuru, ruswa, hamwe nihungabana ryimashini.

 

1. Byiza cyane - birwanya ubushyuhe

Ubushyuhe bwo hejuru - imbaraga: Nickel - ibivanze (nka Inconel 718) bigumana imbaraga nyinshi hejuru ya dogere 700, biruta kure cyane ibyuma bitagira umwanda na titanium.

Antioxidation & Anti - kunyerera: Filime yuzuye ya Cr₂O₃ oxyde igaragara hejuru, ikumira okiside yubushyuhe - (nka GH 2132 ikoreshwa mubyuma bya gaz turbine).

Uburebure - maremare - ituze ryubushyuhe: Bikwiranye nigihe kirekire - igihe kinini - serivisi yubushyuhe bwibidukikije muri moteri yindege, guhinduranya ingufu za kirimbuzi, nibindi bisanzwe:

Moteri yo mu kirere turbine blade (Incoloy 800HT)

Amashanyarazi yamashanyarazi yamashanyarazi (Incoloy 800H)

 

2. Kurwanya ruswa idasanzwe

Kurwanya ruswa kuri acide & alkalis: Ikora neza cyane mubitangazamakuru bikomeye byangirika nka acide sulfurike, aside hydrochloric, na aside hydrofluoric (urugero, Hastelloy C-276 irwanya ruswa).

Kurwanya chloride ion yangirika: Hafi ntabishobora kwangirika mumazi yinyanja hamwe n’ibiti byangiza umunyu (urugero, Monel K-500 ikoreshwa mubwubatsi bwa marine).

Kurwanya guhangayikishwa no kwangirika (SCC): Birakwiriye kubidukikije bya peteroli na gaze birimo hydrogen sulfide (H₂S) (urugero, Incoloy 925). Porogaramu isanzwe:

Icyombo gikora imiti (Hastelloy B-3)

Ibikoresho byo mu nyanja (Inconel 625)

 

3. Imbaraga zikomeye zumukanishi & kurwanya umunaniro mwiza

Imbaraga nyinshi: Binyuze mu gisubizo gikomeye + kuvura gusaza (nka 'icyiciro Ni₃ (Al, Ti)), imbaraga zingana zirashobora kugera kuri MPa zirenga 1000 (nka Inconel X-750).

Kurwanya - umunaniro & anti - gusudira: Bikwiranye n’ibidukikije umunaniro - (nk'ibikoresho byo mu kirere).

Ubushyuhe buke - Ubushyuhe bukabije: Igumana plastike nziza kuri dogere -200 (nkibikoresho byo kubika amazi ya hydrogène). Porogaramu isanzwe:

Ibikoresho bya moteri ya roketi (Inconel 718)

Byimbitse - ibikoresho byo gucukura inyanja (Monel K-500)

Nexus Nova yibanda cyane kuri - imikorere ya nikel - ishingiye ku bicuruzwa bivangwa n’ibisigazwa, birimo imiyoboro idafite isahani, amasahani, ibyuma bifata imiyoboro, flanges, hamwe n’imiyoboro, kandi ikorera mu bice bitandukanye nka peteroli, inganda z’imiti, ingufu, n’ubwubatsi bwo mu nyanja. Isosiyete yiyemeje gutanga ibicuruzwa byizewe kubakiriya bisi binyuze muburyo bunoze bwo gukora nuburyo bunoze bwo kugenzura ubuziranenge.
