Raws li cov txheej txheem electroplating feem ntau cuam tshuam nrog kev tso dej ntawm cov substrate rau hauv lub plating da dej, hydrogen los ntawm cov dej tuaj yeem sib koom ua ke rau saum npoo ntawm substrate nrog rau cov hlau ionsQhov no tuaj yeem ua rau muaj kev phom sij hu ua hydrogen embrittlement.
Vim li cas hydrogen embrittlement tshwm sim?
Hydrogen Embrittlement tshwm sim thaum cov hlau ua nkig vim qhov kev taw qhia thiab nthuav tawm ntawm hydrogen rau hauv cov khoom. … Qhov no tshwm sim thaum muaj kev ntxhov siab txaus rau cov khoom siv hydrogen-embritttled.
Puas nickel plating ua rau hydrogen embrittlement?
1] saum toj no, nws tuaj yeem pom tias cov dej acidic plating xws li npib tsib xee plating, npib tsib xee alloy plating, thiab chloride zinc plating muaj qis hydrogen embrittlement tus nqi, tab sis alkaline plating da dej xws li zinc cyanide da dej thiab tooj liab cyanide da dej muaj feem yuav ua rau hydrogen embrittlement.
Dab tsi ua rau hydrogen embrittlement hauv hlau alloy?
Hydrogen kuj tseem tuaj yeem qhia lub sijhawm (sab nraud embrittlement) los ntawm kev cuam tshuam ib puag ncig (av thiab tshuaj, suav nrog dej), txheej txheem corrosion (tshwj xeeb tshaj yog galvanic corrosion) suav nrog corrosion ntawm txheej txheej thiab kev tiv thaiv cathodic. Hydrogen atoms yog me me thiab diffuse interstitially hauv steels.
Yuav ua li cas hydrogen de embrittlement txheej txheem?
De-embrittlement yog txheej txheem ntawm cov hlau tawv tawv, tshwj xeeb yog cov hlau tsis muaj zog hydrogen uas tau ua tsis ncaj ncees rau hydrogenQhov kev raug hydrogen no ua rau cov hlau tawg thiab tawg; kev puas tsuaj rau cov hlau muaj zog thiab lwm yam hlau siv.
