Cov txheej hnav-tiv taus ntawm hnav-resistant alloy raj yog txawv, thiab feem ntau tswj ntawm 3-120mm, yog li nws cov hardness theem kuj txawv. Piv nrog rau cov khoom siv zoo tib yam hnav-resistant kav lossis lwm yam khoom siv, qhov ua haujlwm tsis zoo ntawm alloy hnav-resistant steel kav yog muaj zog dua, thiab kev puas tsuaj los ntawm kev txau thiab cov tshuaj tsuag thermal yog ntau dua. Kev puas tsuaj-resistant txheej ntawm hnav-resistant kav yog kev sib xyaw ua ke ntawm metallurgy, nrog kev sib xyaw ua ke siab zog.
Txawm hais tias nws muaj kev cuam tshuam, lub zog tuaj yeem nqus tau thaum muaj kev cuam tshuam, thiab hnav-resistant txheej yuav tsis poob. Yog tias nws tuaj yeem tsim nyog rau kev vibration muaj zog thiab cuam tshuam, qhov no tsis tuaj yeem lees txais cov khoom siv pov tseg-resistant thiab cov ntaub ntawv ceramic.
Txawm hais tias cov kav dej galvanized zoo tib yam tuaj yeem nce ntxiv tom qab kev kho cua sov lossis qhov chaw carburizing, nitrogen seepage, thiab lwm yam, yog tias lub hardness ntawm no puas-resistant alloy tube yog siab dhau lawm, nws yuav tev tawm sai sai. Cov ntaub ntawv mos kuj tseem tuaj yeem hnav ntau dua.
Yog vim li cas vim li cas cov alloy hnav tsis kam yog hnav-resistant feem ntau yog vim lawv tsis tsuas yog muaj cov tawv tawv, tab sis kuj muag cov substrates. Feem ntau, nyob rau hauv tus txheej txheem ntawm hnav, yuav muaj ib co los ntawm cov khoom uas yuav muab kev koom ua ke rau hauv lub mos substrate yam tsis muaj kev puas tsuaj loj rau saum npoo.
Yog hais tias lub hardness ntawm cov yeeb nkab substrate qauv yog kuj siab, lub abrasive los yog lwm yam khoom ntawm lub caij nplooj zeeg yuav sib tsoo txhua lwm yam thaum lub sij hawm cov txheej txheem ntawm kev txav, thiab yuav ua kom puas lub substrate qauv sai.
Rau galvanized steel kav, hardness tsuas yog ib qho ntawm cov tsis, uas kuj muaj feem xyuam rau nws cov tshuaj Cheebtsam, tab sis raws li ib tug tseem ceeb parameter rau kev ntsuas cov kev ua tau zoo ntawm cov kav dej, nws yuav tsum tau them nyiaj mloog mus ntxiv.
