Nickel Base Alloy nrog oxidation thiab corrosion resistant
Daim ntawv thov
Nickel puag alloy hmoov yog cov khoom siv ua haujlwm siab uas tau siv dav hauv ntau lub lag luam, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias thiab corrosive ib puag ncig.Nws zoo corrosion kuj thiab high-temperature oxidation kuj ua rau nws ib tug nrov xaiv rau coatings ntawm hlau thiab tsis tshua muaj hlau alloy steel qhov chaw nyob rau hauv high-temperature tej yam kev mob.Nws kuj tseem siv los ua cov txheej txheem sib txuas ntawm carbide txheej, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv hnav-tiv taus.
Cov khoom
Cov hmoov yog tsim los ntawm npib tsib xee, chromium, thiab lwm yam khoom, uas muab nws zoo heev corrosion kuj thiab high-temperature stability.Cov hmoov tuaj yeem tsim cov txheej txheem uas tuaj yeem ua haujlwm ntawm qhov kub txog li 980ºC, ua rau nws tsim nyog siv rau qhov chaw hnyav.Cov txheej kuj muaj qhov zoo toughness thiab mechanical kev ua tau zoo, uas ua rau nws zoo tagnrho rau siv nyob rau hauv hnav-resistant daim ntaub ntawv.
Kev tsim khoom
Cov nickel puag alloy hmoov yog tsim los ntawm kev siv roj atomization txheej txheem.Cov txheej txheem cuam tshuam nrog melting cov ntaub ntawv raw thiab tom qab ntawd atomizing lawv mus rau hauv cov hmoov zoo siv cov pa roj.Lub resulting hmoov muaj ib tug uniform particle loj thiab zoo flowability, uas ua rau nws yooj yim mus lis thiab txheej txheem.
Kev siv
Nickel puag alloy hmoov yog dav siv nyob rau hauv ntau yam kev lag luam, nrog rau aerospace, lub zog tsim, thiab kev ua tshuaj.Nws yog feem ntau siv los ua cov khoom siv los tiv thaiv cov hlau thiab cov hlau tsis tshua muaj hlau nyob rau hauv qhov kub thiab txias thiab corrosive.Nws kuj yog siv los ua ib theem kev sib txuas ntawm carbide txheej, ua rau nws zoo tagnrho rau kev hnav-resistant daim ntaub ntawv.Cov hmoov tuaj yeem siv tau siv ntau yam txheej txheem thermal txau, suav nrog cov tshuaj tua hluav taws, tshuaj tsuag plasma, thiab cov tshuab hluav taws xob siab tshaj tawm oxy-roj (HVOF) tshuaj tsuag.
Xaus
Nickel puag alloy hmoov yog cov khoom siv ua haujlwm siab uas tau siv dav hauv ntau qhov kev lag luam rau nws cov corrosion kuj zoo heev thiab kub-kub oxidation kuj.Cov txheej txheem roj atomization xyuas kom meej tias cov hmoov muaj qhov sib txawv me me thiab zoo flowability, ua kom yooj yim rau kev tswj thiab txheej txheem.Nws qhov kub thiab txias stability, toughness, thiab mechanical kev ua tau zoo ua rau nws yog ib qho kev xaiv zoo tagnrho rau siv nyob rau hauv ib puag ncig hnyav thiab hnav-resistant daim ntaub ntawv.
