Inconel imhuri ye austenitic nickel chromium yakavakirwa super alloys.
Inconel alloys ndeye oxidation corrion resistance zvinhu zvakanyatsokodzera kushanda munzvimbo dzakanyanyisa pasi pekumanikidzwa uye.
kupisa.Kana yapiswa,Inconel inogadzira chipembere,chakatsiga,inopfuudza oxide layer inodzivirira pamusoro kubva pakumwe kurwisa.Inconel inochengeta.
simba pamusoro petembiricha yakafara siyana, inokwezva kune yakakwira tembiricha yekushandisa uko aluminium nesimbi zvinogona kunyura mukudonha.
semhedzisiro ye thermally induced crystal vacancies.Inconel's high tembiricha simba inogadzirwa nemhinduro yakasimba.
kusimbisa kana kunaya kuoma, zvichienderana nealloy.
Inconel 718 is nickel-chromium-molybdenum alloy yakagadzirirwa kurwisa nzvimbo dzakasiyana-siyana dzinoparadza zvakanyanya, pitting uye crevice corrosion. Iyi nickel simbi alloy inoratidzawo goho rakanyanya kukwirira, tensile, uye zvinokambaira-kuputika zvivakwa pakupisa kwakanyanya. Iyi nickel alloy inoshandiswa kubva kune cryogenic tembiricha kusvika kushumiro yenguva refu pa 1200 ° F. Chimwe chezvinhu zvinosiyanisa zveInconel 718's kuumbwa ndiko kuwedzera kweniobium kubvumira kuomarara kwezera izvo zvinobvumira kuomeswa uye welding pasina kuoma kwega panguva yekudziya uye kutonhora. . Kuwedzerwa kwe niobium kunoshanda pamwe ne molybdenum kuomesa matrix alloy uye kupa simba rakakwirira pasina kusimbisa kupisa. Zvimwe zvakakurumbira nickel-chromium alloys zera rakaomeswa kuburikidza nekuwedzera kwealuminium uye titanium. Iyi nickel simbi alloy inogadzirwa zviri nyore uye inogona kugadzirwa mukati meiyo annealed kana kunaya (age) yakaoma mamiriro. Iyi superalloy inoshandiswa mumaindasitiri akasiyana-siyana akadai seaerospace, kugadzira makemikari, mainjiniya emugungwa, midziyo yekudzora kusvibisa, uye mareactor enyukireya.
