Hayness 188 (Alloy 188) ni cobalt-fatizo ivanze ifite imbaraga zidasanzwe -ubushyuhe bwinshi hamwe no kurwanya okiside nziza kuri 2000 ° F (1093 ° C).Urwego rwo hejuru rwa chromium ruherekejwe nuduto duto twa lanthanum bitanga urugero rukomeye kandi rukingira.Amavuta kandi afite imbaraga zo guhangana na sulfidisiyonike hamwe no guhagarara neza kwa metallurgjique nkuko bigaragazwa nubworoherane bwayo nyuma yigihe kinini cyo guhura nubushyuhe bwo hejuru.Gukora neza no gusudira bifatanyiriza hamwe kugirango ibivange bigire akamaro mubikorwa bya gaz turbine nko gutwika, gufata flame, imirongo hamwe numuyoboro winzibacyuho.

•Imbaraga na okiside irwanya 2000 ° F.
•Guhindagurika nyuma yubusaza
•Kurwanya sulfate kubitsa bishyushye
Moteri ya gaz turbine yamashanyarazi, utubari twa spray, abafite flame na liner nyuma yo gutwika
