Bisetallic compound txheej hnav-resistant steel phaj yog cov khoom siv phaj tshwj xeeb siv rau thaj tsam loj ntawm kev hnav. Nws yog tsim los ntawm cov pa roj carbon zoo tib yam los yog cov hlau tsis tshua muaj hlau nto los ntawm cov txheej txheem txheej txheej thickness nrog siab hardness thiab zoo heev hnav tsis kam.
Bimetal composite hnav-resistant steel phaj yog tsim los ntawm cov pa roj carbon tsawg thiab alloy hnav-resistant txheej, thiab cov txheej txheem tiv thaiv feem ntau suav rau 1 / 3-1 / 2 ntawm tag nrho cov tuab. Thaum ua hauj lwm, lub matrix muab cov kev ua tau zoo xws li lub zog, toughness thiab plasticity, thiab cov hnav-resistant txheej muab cov hnav-tiv taus kom tau raws li cov kev cai ntawm kev ua hauj lwm teev.
Hnav-resistant steel phaj alloy hnav-resistant txheej thiab matrix yog metallurgical ua ke. Los ntawm cov khoom siv tshwj xeeb, kev siv cov txheej txheem vuam tsis siv neeg, lub siab hardness nws tus kheej tiv thaiv alloy vuam hlau yog sib npaug welded ntawm lub substrate, cov txheej txheem sib xyaw ib mus rau ob txheej rau ntau txheej, cov txheej txheem sib xyaw vim sib txawv alloy shrinkage piv, niaj hnub transverse. tawg, uas yog cov yam ntxwv zoo kawg nkaus ntawm hnav-resistant steel phaj.
Cov txheej hnav-tiv taus yog tsim los ntawm chromium alloy, thiab manganese, molybdenum, niobium, npib tsib xee thiab lwm yam alloys kuj ntxiv. Cov carbide nyob rau hauv cov ntaub so ntswg metallographic yog faib nyob rau hauv fiber ntau, thiab cov kev taw qhia fiber ntau yog perpendicular rau saum npoo. Cov carbide microhardness tuaj yeem ncav cuag saum HV1700-2000, thiab qhov tawv tawv tuaj yeem ncav cuag HRc 58-62. Alloy carbide muaj qhov ruaj khov ntawm qhov kub thiab txias, tswj kev ua haujlwm siab, tab sis kuj muaj cov khoom zoo antioxidant, nyob rau hauv 500 degree tag nrho siv.
Wear-resistant steel phaj muaj kev hnav tsis kam thiab kev ua haujlwm zoo, tuaj yeem txiav, khoov, vuam, vuam, vuam, ntsaws vuam, ntsia liaj qhov rooj txuas nrog lwm cov qauv, hauv cov txheej txheem ntawm kev saib xyuas lub sijhawm, yooj yim, siv dav hauv metallurgy. , thee, cement, hluav taws xob, iav, mining, cov khoom siv hauv tsev, cib thiab lwm yam kev lag luam, piv nrog lwm cov ntaub ntawv, muaj kev ua haujlwm siab, tau txais kev pom zoo los ntawm kev lag luam thiab cov tuam txhab ntau dua.
