Galvanized steel kav feem ntau siv rau hauv kev tsim cov khoom tseem ceeb uas xav tau tshwj xeeb hnav tsis kam thiab tawg tsis kam, txawm tias lawv cov khoom siv xws li siab tawv, zoo heev khoov, thiab vuam muaj peev xwm. Lub thickness ntawm cov hnav-resistant txheej nyob rau hauv alloy hnav-resistant kav sib txawv, 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 txheem hnav-tiv taus ntawm cov kav dej no yog metallurgically sib raug zoo rau lub substrate, kom ntseeg tau tias muaj kev ruaj ntseg ruaj khov.
Txawm tias muaj kev cuam tshuam, txheej hnav-tiv taus tuaj yeem nqus tau lub zog thaum lub sijhawm ua haujlwm, tiv thaiv detachment. Qhov no ua rau lawv tsim nyog rau cov ntawv thov uas muaj kev vibrations hnyav thiab cuam tshuam, uas tsis tuaj yeem ua rau cov ntaub ntawv pov thawj hnav-resistant thiab cov ntaub ntawv ceramic.
Thaum lub zog saum npoo ntawm cov kav dej galvanized zoo tib yam tuaj yeem txhim kho los ntawm kev kho cua sov, qhov chaw carburizing, lossis nitriding, kev nyuaj siab heev hauv cov kav hlau uas tsis muaj steel hlau yuav ua rau muaj kev sib kis sai, cuam tshuam rau kev hnav tsis kam. Paradoxically, qee cov ntaub ntawv softer yuav pom zoo hnav tsis kam.
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 lub sij hawm hnav, txhua yam khoom siv detached integrates rau hauv cov mos matrix, minimizing nto puas.
Yog hais tias lub hardness ntawm cov yeeb nkab matrix qauv kuj yog siab, ntog abrasives los yog lwm yam khoom yuav sib tsoo tawm tsam ib leeg thaum lub sij hawm txav, ua kom lub cev puas tsuaj ntawm cov qauv matrix. Rau galvanized steel kav, hardness tsuas yog ib qho parameter, nrog rau cov tshuaj muaj pes tsawg leeg kuj ua lub luag haujlwm tseem ceeb. Raws li qhov taw qhia tseem ceeb ntawm kev ua haujlwm ntawm cov kav dej, nws tsim nyog tau txais kev saib xyuas kom siab.
