Super alloys ine kugona kushanda pakupisa kwakanyanya uye kushushikana kwemagetsi, uye zvakare uko kugadzikana kwepamusoro kunodiwa.Vane zvakanaka zvinokambaira uye oxidation kuramba, uye zvinogona kugadzirwa mune akasiyana maumbirwo.Vanogona kusimbiswa ne-soli-solution kuomesa, kushanda kuoma, uye kuoma kwemvura.
Super alloys inoumbwa nehuwandu hwezvinhu mumhando dzakasiyana dzemusanganiswa kuti uwane mhedzisiro yaunoda.Ivo vanoiswazve mumapoka matatu akadai secobalt-based, nickel-based, uye iron-based alloys.
Incoloy(r) alloy 825 is an austenitic nickel-iron-chromium alloy iyo inowedzerwa pamwe nezvimwe zvinhu zvealloying kuitira kuti ivandudze makemikari ayo anodzivirira corrosion.Iyo inotevera dhatabheti ichapa rumwe ruzivo nezve Incoloy(r) alloy 825.
