I-Haynes 188 Nickel Alloy
I-Haynes 188 (UNS R30188) iyi-cobalt{2}}esekelwe ku-superalloy equkethe u-22% we-chromium, u-14% we-tungsten kanye namanani okulandelela e-lanthanum. Inamandla aphezulu aphezulu-ezinga lokushisa eliphezulu (1095 degree) kanye nokumelana ne-oxidation, futhi imelana nosawoti oncibilikisiwe kanye nokugqwala kwe-sulfide. Ilungele ukusetshenziswa ezindaweni ezeqisayo njengamagumbi omlilo wezinjini zezindiza kanye nezingxenye ze-turbine yegesi.

Isici
Amandla aphezulu-ezinga lokushisa aphakeme, ukumelana ne-oxidation, ukumelana nosawoti we-chloride encibilikisiwe, i-sulfate{1}}idala ukumelana nokugqwala okushisayo, ukuzinza kwe-thermal, kanye nokumelana ne-gaseous sulfidation.
Izinhlelo zokusebenza
Ukulungiswa kwe-turbine yegesi: Ama-combustors, ama-transition ducts, izingxenye ezibalulekile zenjini ye-aerospace
Amashadi ashisayo: i-haynes 188 i-nickel alloy, i-China haynes 188 abakhiqizi be-nickel alloy, abahlinzeki, imboni
