Thaum koj hnov 'nickel-based alloy mechanical qhov chaw,' qhov kev xav tam sim no feem ntau ua tau zoo heev - dav hlau cav, turbines, qhov zoo kawg nkaus siv. Qhov ntawd tsis yog qhov tsis ncaj ncees lawm, tab sis nws yog qhov kev nkag siab ntawm qhov chaw uas tuaj yeem ua rau raug nqi tsis zoo hauv kev qhia thiab kev yuav khoom. Cov dab neeg tiag tiag yog nyob rau hauv kev sib tsoo, machining chatter, warping thaum lub sij hawm kho cua sov, thiab nyob ntsiag to kev vam meej ntawm ib feem uas yooj yim tsis poob nyob rau hauv siab. Muaj peev xwm thiab saib xyuas kev tsim khoom rau cov khoom lag luam hauv kev xav tau, Kuv tau pom qhov sib txawv ntawm daim ntawv cog lus thiab kev muaj tiag hauv khw hauv pem teb. Nws tsis yog hais txog kev xaiv Inconel 718 lossis Hastelloy C-276 los ntawm phau ntawv teev npe; Nws yog hais txog kev nkag siab tias cov khoom siv yuav coj li cas los ntawm cov hlau molten kom tiav, cov khoom siv ua haujlwm.
Lub Alloy tsis yog qhov pib taw tes; Hom Failure Yog
Ntau qhov haujlwm dhau los pib nrog peb xav tau ib feem ntawm nickel alloy. Qhov ntawd yog rov qab. Kev sib tham yuav tsum pib nrog cov kev ntxhov siab tshwj xeeb: nws puas yog cyclic thermal qaug zog, raug cov tshuaj chloride tas li, los yog kev sib xyaw ntawm kev yaig thiab kub nruab nrab? Piv txwv li, kev qhia Inconel 625 rau nws qhov kev tiv thaiv corrosion dav dav thaum qhov kev hem thawj tseem ceeb yog sulfidation ntawm qhov kub thiab txias yog qhov pov tseg ntawm peev. Kuv nco qab txog lub valve tivthaiv rau kev ua tshuaj nyob rau hauv qhov chaw thawj spec yog rau ib tug generic high-nickel alloy. Tom qab soj ntsuam cov txheej txheem kwj, peb hloov mus rau ntau dua chromium, qis hlau sib txawv, uas muaj kev tiv thaiv zoo dua rau qhov acidic ib puag ncig yam tsis muaj tus nqi tsis tsim nyog ntawm qib txawv dua. Cov hlau yog ib qho cuab yeej, tsis yog khoom plig.
Qhov no yog qhov kev koom tes nrog lub chaw tsim khoom thiab lub khw muag khoom uas tau txais qhov sib txawv no yog qhov tseem ceeb. Koj xav tau ib tus neeg muag khoom uas nug vim li cas ua ntej muaj pes tsawg. Ib lub khw zoo li Qingdao Qiangsenyuan Technology Co., Ltd.
