I-Incoloy A286 yi-Fe-25Ni-15Cr esekwe kwi-superalloy eqiniswe ngokongezwa kwe-molybdenum, i-titanium, i-aluminiyam, i-vanadium kunye ne-trace boron.Ngaphantsi kwe-650 ℃, inamandla esivuno esiphezulu, amandla ahlala ixesha elide kunye nokurhubuluza, iplastiki yokulungiswa kakuhle kunye nokusebenza okwanelisayo kwe-welding.Ilungele ukwenziwa kobushushu obuphezulu beenjini ze-aero-injini ezisebenza phantsi kwe-650 ℃ ixesha elide, njengediski ye-turbine, idiski yokucofa, i-rotor blade kunye ne-fastener, njl.I-alloy ingasetyenziselwa ukuvelisa iimveliso eziguquguqukayo zeemilo ezahlukeneyo, ezifana neepleyiti, iiplate, iiplate, iintonga, iingcingo kunye neengxenye ze-annular.Umgangatho ophezulu we-A286 alloy uphuhliswa ngesiseko se-A-286 ingxubevange.Ngethuba nje ukucoceka kwe-alloy kuphuculwe, umxholo wegesi ulinganiselwe, umxholo wezinto eziphantsi zokunyibilika zilawulwa, kwaye inkqubo yonyango lobushushu iyahlengahlengiswa, ukuze kuphuculwe amandla okushisa kunye nokusebenza kwexesha elide le-thermal. ingxubevange.
