I-Inconel lusapho lwe-austenitic nickel chromium esekwe kwii-alloys ezinkulu.
I-inconel alloys zizinto zokuxhathisa i-oxidation corrion eyilungele kakuhle inkonzo kwiindawo eziphantsi koxinzelelo kunye noxinzelelo.
Ubushushu.Xa ifudunyezwa, i-Inconel yenza irhikhi, isizinzile, isaleko seoksidi edlulayo ekhusela umphezulu ekuhlaselweni ngakumbi.Inconel iyayigcina.
amandla kuluhlu olubanzi lobushushu, anomtsalane kwizicelo zobushushu obuphezulu apho ialuminiyam kunye nentsimbi zinokunikezela
ngenxa yezithuba zekristale ezibangelwa thermally.Amandla aphezulu obushushu beInconel aphuhliswa sisisombululo esiqinileyo.
ukuqinisa okanye ukuqina kwemvula, kuxhomekeke kwi-alloy.
I-Inconel 718 yi-nickel-chromium-molybdenum alloy eyenzelwe ukuxhathisa uluhlu olubanzi lweendawo ezinobungozi kakhulu, i-pitting kunye ne-crevice corrosion. Le nickel steel alloy ikwabonisa isivuno esiphezulu kakhulu, i-tensile, kunye neempawu eziqhekezayo kumaqondo obushushu aphezulu. Le ingxubevange nickel isetyenziswa amaqondo obushushu cryogenic ukuya kwinkonzo ixesha elide 1200 ° F. Enye yeempawu ukwahlula ukubunjwa Inconel 718's ukongeza niobium ukuvumela ubudala lukhuni evumela annealing kunye welding ngaphandle kokuqina ngokuzenzekelayo ngexesha lokufudumeza kunye nokupholisa. . Ukongezwa kwezenzo ze-niobium kunye ne-molybdenum ukuqinisa i-matrix ye-alloy kunye nokubonelela amandla aphezulu ngaphandle kokuqiniswa kwonyango lokushisa. Ezinye iialloyi ezidumileyo zenickel-chromium ziqiniswa ngokweminyaka ngokongezwa kwe-aluminiyam kunye ne-titanium. Le nickel steel alloy yenziwe ngokulula kwaye inokudityaniswa nokuba i-annealed okanye imvula (iminyaka) yokuqina. Le superalloy isetyenziswa kumashishini ahlukeneyo afana ne-aerospace, i-chemical processing, i-marine engineering, izixhobo zokulawula ungcoliseko, kunye nezixhobo zenyukliya.
