Kev xaiv ntawm SMC pwm nto kho

Txhawm rau txhim kho qhov hnav tsis kam thiab corrosion tsis kam ntawm pwm nto, nws feem ntau raug kho kom haum rau saum npoo.
Chromium plating yog ib qho ntawm feem ntau siv txoj kev kho deg. Cov txheej txheej chromium plating muaj zog passivation muaj peev xwm nyob rau hauv cov huab cua, muaj peev xwm tswj tau cov xim hlau luster ntev, thiab tsis muaj tshuaj tiv thaiv tshwm sim nyob rau hauv ntau yam acidic media. Lub txheej hardness ntawm 1000HV yog sib npaug rau HRC65, yog li nws muaj kev hnav zoo heev. Cov chromium plating txheej kuj muaj cov cua kub tsis kam, thiab nws cov tsos thiab hardness tsis tau hloov pauv loj thaum rhuab mus rau 500 degrees hauv huab cua.
Nitriding muaj qhov zoo ntawm kev ua haujlwm kub (feem ntau 550 ~ 570 degrees), pwm me me deformation thiab siab hardness ntawm infiltrated txheej (txog 1000 ~ 1200HV, sib npaug rau HRC65 ~ 72), yog li nws kuj yog qhov tsim nyog rau kev kho deg. molded yas khoom pwm. Cov hlau uas muaj cov hlau alloy xws li chromium, molybdenum, txhuas, vanadium, thiab titanium muaj cov khoom zoo nitriding zoo dua li cov hlau. Nitriding kev kho mob thaum siv los ua SMC pwm tuaj yeem txhim kho kev hnav tsis kam.
