Wear-resistant alloy kav muaj qhov sib txawv thicknesses ntawm hnav-resistant khaubncaws sab nraud povtseg, feem ntau yog li ntawm 3 mus rau 120mm, uas ua rau sib txawv hardness theem. Piv nrog rau cov kav hlau uas tsis muaj hlau tsis zoo lossis lwm yam khoom siv, cov kav hlau alloy hnav-tiv taus steel yeeb nkab muaj qhov hnyav dua hnav tsis kam, deb tshaj qhov ua tiav los ntawm cov tshuaj tsuag vuam thiab thermal txau. Cov txheej hnav-tiv taus ntawm cov kav dej no yog metallurgically bonded rau lub substrate, kom ntseeg tau tias muaj zog daim ntawv cog lus.
Txawm tias muaj kev cuam tshuam, txheej hnav-tiv taus tuaj yeem nqus tau lub zog thaum lub sijhawm cuam tshuam, tiv thaiv detachment. Lub peev xwm no, tsim nyog rau cov xwm txheej uas muaj kev vibration hnyav thiab cuam tshuam, tsis tuaj yeem ua tiav los ntawm cov ntaub ntawv pov thawj hnav-resistant thiab cov ntaub ntawv ceramic.
Thaum cov kav dej galvanized zoo tib yam tuaj yeem raug kho cua sov los yog ntog carburizing, nitriding, thiab lwm yam, txhawm rau txhim kho lub zog ntawm lub zog, kev nyuaj siab heev hauv cov kav dej hnav-resistant alloy yuav ua rau flaking sai, cuam tshuam rau hnav tsis kam. Hauv qhov sib piv, qee cov ntaub ntawv softer tuaj yeem pom kev hnav zoo dua.
Kev hnav tsis kam ntawm alloy hnav-resistant kav feem ntau stems los ntawm lawv kev sib xyaw ntawm cov khoom tawv thiab cov mos matrix. Thaum cov txheej txheem hnav, qee cov ntaub ntawv tshem tawm sib xyaw rau hauv cov matrix mos, txo qhov kev puas tsuaj ntawm qhov chaw.
Yog hais tias lub hardness ntawm cov yeeb nkab substrate qauv kuj yog siab, abrasive hais los yog lwm yam khoom ntog mus rau nws yuav sib tsoo tawm tsam ib leeg thaum lub sij hawm txav, accelerating kev puas tsuaj ntawm substrate qauv.
Rau galvanized steel kav, hardness tsuas yog ib qho parameter ntawm ntau, thiab lawv cov tshuaj muaj pes tsawg leeg kuj plays lub luag haujlwm. Txawm li cas los xij, raws li qhov tseem ceeb ntawm kev ntsuas cov yeeb nkab kev ua tau zoo, nws tsim nyog saib xyuas tshwj xeeb.
