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.

Thaum electroplating ib tsab xov xwm nrog nyiaj cov electrolyte siv yog?
Yog li ntawd, cov electrolyte siv rau electroplating ib tsab xov xwm nrog nyiaj yog Sodium argentocyanide tov uas qhia kev xaiv C raws li kev xaiv raug. Lus Cim: Nyob rau hauv cov txheej txheem ntawm cov nyiaj plating cov khoom los yog ib qho tshuaj ntsuam xyuas uas yuav tsum tau plated yog tsim los ntawm cathode ntawm ib qho electrolytic cell .
Yuav ua li cas yog isotope ntawm hydrogen muaj nyob rau hauv cov dej hnyav?
Dej Hnyav (D 2 O) lossis deuterium oxide yog tsim los ntawm ob lub atom ntawm deuterium thiab ib atom ntawm oxygen. Deuterium yog ib qho isotope ruaj khov ntawm hydrogen nrog ob npaug ntawm qhov loj ntawm hydrogen vim muaj cov neutron ntxiv hauv nws cov nucleus.
Cov hlau twg yog siv rau hauv electroplating?
Cov hlau uas siv hauv cov txheej txheem electroplating suav nrog dub thiab nyiaj npib tsib xee, chromium, tooj dag, cadmium, tooj liab, kub, palladium, platinum, ruthenium, nyiaj, tin thiab zinc Peb Feem ntau pom zoo kom siv Qib S lossis N Nickel, cadmium pellets, CDA 101 OFHC Copper, tooj dag alloys, tin anodes thiab zinc .
Yuav ua li cas txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau?
Ntau tus neeg ua tiav lawv txoj kev kho hniav thiab muaj cov hniav zoo nkauj, txawm li cas los xij, thaum lawv luag ntxhi lawv pom cov hniav luv luv lossis cov pos hniav ntau dhau "gummy luag". Cosmetic crown lengthening yog ib txoj hauv kev yooj yim uas tuaj yeem ua tau zoo heev ua kom lub ntsej muag luag ntxhi ntawm cov neeg mob no .
Yuav sau li cas vim li cas thiab yog vim li cas?
Kev txhais ntawm yog vim li cas thiab (tus) yog li ntawd: yog vim li cas rau ib yam Nws piav qhia vim li cas thiab yog li ntawd ntawm tus nqi nce . Yuav ua li cas thiab yog vim li cas? Txhua qhov laj thawj thiab qhov laj thawj, ib yam li hauv Nws tau mus rau qhov laj thawj thiab yog li ntawm lub koom haum kev saws me nyuam txoj cai thiab cov txheej txheem.
