Alloy 188, tseem hu ua Cobalt Alloy 188, yog qhov kub-kub superalloy uas nthuav tawm lub zog tshwj xeeb, oxidation tsis kam, thiab ductility thaum raug rau qhov kub ntev li ntawm 1400 txog 1600 degrees Fahrenheit. Nws yog nyob rau hauv chav kawm ntawm cobalt-raws li alloys, uas muaj qhov zoo ntawm cov nickel-based qib nyob rau hauv cov nqe lus ntawm high-temperature creep resistance.
Tshuaj muaj pes tsawg leeg,%
Nrog nws cov tshwj xeeb muaj pes tsawg leeg, Alloy 188 yog cov tshuaj muaj zog ntxiv los ntawm 14% tungsten ntxiv, ntxiv txhim kho los ntawm muaj M6C thiab M23C6 carbides. Qhov kev sib xyaw ua ke ntawm cov ntsiab lus alloying no ua rau cov khoom siv zoo heev thiab ua haujlwm rau oxidation, ua rau Alloy 188 yog qhov kev xaiv zoo tshaj plaws rau kev thov rau cov ntawv thov hauv qhov chaw kub kub.
Alloy 188 pom kev siv dav hauv kev lag luam xws li aerospace, roj turbine xyaw, petrochemicals, thiab nuclear fais fab, qhov chaw kub kub ua haujlwm thiab corrosion kuj tseem ceeb heev. Nws muaj peev xwm tswj tau lub zog thiab oxidation tsis kam nyob rau hauv cov xwm txheej nyuaj ua rau nws tsim nyog rau kev tsim turbine hniav, combustion chamber Cheebtsam, tshav kub exchangers, thiab catalyst txhawb cov qauv.
Piv rau cov nickel-raws li alloys, cobalt alloys zoo li Alloy 188 nthuav tawm kev nkag siab zoo ntawm qhov kub thiab txias. Qhov no ua rau Alloy 188 qhov kev xaiv txhim khu kev qha rau cov ntawv thov uas cuam tshuam nrog lub sijhawm ntev ntawm qhov kub siab.
Nyob rau hauv cov nqe lus ntawm fabrication, Alloy 188 muaj kev yooj yim ntawm kev ua thiab tuaj yeem welded siv ntau txoj hauv kev, nrog rau kev siv phau ntawv thiab tsis siv neeg xws li hluav taws xob nqaj, roj tungsten arc, thiab vuam tsis kam.
Hauv cov ntsiab lus, Alloy 188 yog cobalt-based superalloy muaj npe nrov rau nws qhov tshwj xeeb kub kub lub zog, oxidation tsis kam, thiab ductility. Nrog nws cov kev daws teeb meem ntxiv dag zog, carbide reinforcement, thiab weldability zoo heev, Alloy 188 yog cov khoom siv txhim khu kev qha rau kev lag luam uas xav tau kev ua haujlwm zoo hauv qhov kub thiab txias.
