Cov pa roj carbon chrome

Lub refractory alloy muaj xws li chromium-raws li alloys nrog rau lwm yam khoom. Piv nrog npib tsib xee, chromium muaj cov ntsiab lus melting ntau dua (1860 degree), muaj zog tshwj xeeb (qhov sib piv ntawm lub zog rau qhov ntom), zoo oxidation tsis kam thiab corrosion kuj ntawm siab sulfur, diesel roj thiab dej hiav txwv. cov ntsiab lus rau chromium tuaj yeem txhim kho lub zog ntawm cov hlau, tab sis cov yas yuav ua tsis zoo, tsuas yog ntxiv cov ntsiab lus nrog ntau dua affinity nrog qhov sib txawv impurity cov ntsiab lus -- carbon, oxygen, nitrogen, xws li cerium, titanium, yttrium tuaj yeem txhim kho cov khoom. yas. Qhov no yog vim hais tias cov ntsiab lus no tuaj yeem cuam tshuam nrog cov impurities interstitial thiab txo cov ntsiab lus daws teeb meem hauv matrix. Lawv feem ntau hu ua "purifiers". Thaum cov ntsiab lus ntawm yttrium yog 0.1 feem pua ​​~ 0.2 feem pua, cov yas ntawm cov hlau yog txhim kho. Los nag los yog dispersion ntxiv dag zog tuaj yeem txhim kho qhov creep tsis kam ntawm chromium alloy ntawm qhov kub thiab txias, thiab theem nag lossis daus los yog tawg tuaj yeem txhim kho cov yas ntawm cov hlau, yog li nws yog qhov zoo los tsim los nag lossis tawg ntxiv ntxiv chromium alloy.
