Thaum nws los txog rau kev vuam, siv cov ntaub ntawv zoo yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo.Cov xov hlau nickel, xws li Alloy 825 (ERNiFeCr-1), yog thawj qhov kev xaiv rau ntau yam kev siv nyuaj. Cov hlau nickel-iron-chromium no tau tsim tshwj xeeb los muab kev ua tau zoo tshaj plaws hauv cov chaw xav tau, ua rau nws yog qhov kev daws teeb meem zoo tshaj plaws rau kev lag luam xws li aerospace, kev ua tshuaj lom neeg thiab kev tsim kho dej hiav txwv.
Alloy 825 (ERNiFeCr-1) paub txog nws txoj kev tiv thaiv xeb zoo heev, ua rau nws tsim nyog rau cov ntawv thov uas feem ntau raug rau cov tshuaj lom neeg hnyav, kub siab thiab cov xwm txheej hnyav. Kev sib xyaw ua ke ntawm nickel, hlau thiab chromium hauv cov hlau no ua kom muaj kev tiv thaiv zoo rau oxidizing thiab txo cov chaw ib puag ncig, muab kev tiv thaiv tsis muaj qhov sib xws tiv thaiv xeb thiab oxidation.
Ntxiv rau nws txoj kev tiv thaiv corrosion zoo heev, Alloy 825 (ERNiFeCr-1) muaj cov khoom siv kho tshuab zoo heev, suav nrog lub zog tensile siab thiab kev tiv thaiv creep zoo heev. Qhov no ua rau nws yog qhov kev xaiv txhim khu kev qha rau cov khoom vuam uas raug rau cov khoom hnyav thiab kub siab, muab kev ruaj khov ntev thiab kev ntseeg siab hauv cov ntawv thov tseem ceeb.
Tsis tas li ntawd xwb, qhov ua tau ntau yam ntawm Alloy 825 (ERNiFeCr-1) ua rau nws tsim nyog rau kev vuam ntau yam khoom siv, suav nrog cov hlau tsis xeb, cov hlau carbon thiab lwm yam hlau nickel. Nws qhov kev vuam zoo heev thiab kev sib raug zoo nrog ntau yam hlau hauv paus ua rau nws yog thawj qhov kev xaiv rau cov neeg tsim khoom thiab cov neeg vuam uas tab tom nrhiav kom ua tiav cov vuam zoo, zoo hauv ntau yam kev siv.
Zuag qhia tag nrho, Alloy 825 (ERNiFeCr-1) sawv tawm ua cov hlau nickel alloy zoo tshaj plaws nrog kev tiv thaiv corrosion zoo heev, cov khoom siv kho tshuab zoo heev thiab kev sib txuas ntau yam. Txawm hais tias koj ua haujlwm rau cov haujlwm nyuaj hauv kev lag luam aerospace, tshuaj lom neeg lossis marine, cov hlau vuam no yog qhov kev xaiv txhim khu kev qha rau cov txiaj ntsig zoo tshaj plaws hauv cov chaw xav tau tshaj plaws.
