Ukumelana nobushushu bokushisa kubhekiselele kwiimpawu zayo ezibalaseleyo zomzimba kunye nezoomatshini ezinokuthi zigcine intsimbi engenasici kubushushu obuphezulu.
Impembelelo yekhabhoni: Ikhabhoni yindlela eyomeleleyo yentsimbi ye-Austenite kunye nokuzinzisa i-austenite kunye nokwandisa ummandla we-Austenitic.Ukukwazi kwekhabhoni ukwenza i-austenitic malunga namaxesha angama-30 kune-nickel.Ikhabhoni yinto yesikhewu.Inokuphucula ngokubonakalayo amandla entsimbi ye-Austenite engenasici ngokuqinisa i-soluble-soluble.Ikhabhoni inokuphucula ukuxhathisa kunye nokumelana nomhlwa kwikloridi eshinyeneyo ephezulu (efana ne-42% mgCl2 isisombululo esibilayo).
Nangona kunjalo, kwi-austenitic steel stainless steel, ikhabhoni ihlala ithathwa njengezinto eziyingozi.Oku kubangelwa ikakhulu kwezinye iimeko (ezifana ne-welding okanye ukufudumeza nge-450 ~ 850 ° C) phantsi kweemeko ezithile kwintsimbi engenasici).Ikhabhoni inokuba njengentsimbi kunye nentsimbi kwintsimbi.I-Chromium yenza i-chromium ephezulu ye-CR23C6 yekhompawundi yekhabhoni, ekhokelela kubuhlwempu be-chromium yendawo, enciphisa ukuxhathisa ukubola kwentsimbi, ngakumbi ukuxhathisa ukubola kokumelana nekristale.ke ngoko.Ukususela ngo-1960, i-chromium-nickel esanda kuphuhliswa i-Austeenian steel stainless steel ininzi i-carbon content ngaphantsi kwe-0.03% okanye i-0.02% uhlobo lwe-ultra-low-carbon.Unokwazi ukuba njengoko umxholo wekhabhoni uyancipha, uvakalelo lwe-crystal corrosion yensimbi luyancipha.I-0.02% inezona ziphumo zicacileyo.Ezinye iimvavanyo zikwabonisa ukuba ikhabhoni inokonyusa ukutyekela kwamanqaku e-chromium Aozoi ensimbi engenasici.Ngenxa yempembelelo eyingozi yekhabhoni, akufuneki kuphela ukuba umxholo wekhabhoni ulawulwe uphantsi kangangoko kunokwenzeka kwinkqubo yokunyibilikisa i-austenite steel stainless, kodwa nakwinkqubo yobushushu obulandelayo, ukusetyenzwa okubandayo kunye nonyango lobushushu, kodwa nokuthintela umphezulu wensimbi engenasici ukunyusa umgangatho wekhabhoni kwaye uphephe i-chromium carbides enqanda i-chromium carbides Ekhethiweyo.
