1.Huv li cas ua kev ua tau zoo ntawm kev sib txawv galvanizing cov txheej txheem sib piv?
Kub-DIP Galvanizing: Micro Cov Khaub Ncaws Raug Los Ntawm Craze Zn-Fe Alloy Txheej
Electrogalvanizing: Hydrogen embrittlement + saum npoo pore ntxhov siab concentration
Neeg kho tshuab Galvanizing: Ua haujlwm txias ua haujlwm rau lub zog ua kom tawv + particle embedding micro qhov tsis zoo
Zinc-Aluminium Txheej: Yooj Yim Mgzn₂ Phase inhibits Bream Kev Loj Hlob
2.Yog li cas lub xeev kev ntxhov siab lub xeev hloov pauv nrog cov txheej txheem sib txawv?
Kub-DIP Galvanizing
430 DEGREEN DEGINIS CAV UA RAU COV LWM YAM THIAB softening ntawm lub substrate, tawm lub zog ↓ 10%
Compressive Kev Nyuaj Siab nce: Cua txias shrinkage tsim 50-80MPA kev ntxhov siab rau saum npoo (muaj txiaj ntsig)
TENSILE LOJ LOJ: Qhov txawv ntawm Kev nthuav tawm thermalient ntawm lub zn-Fe txheej txheej (Δ theem) ua rau 200mpa tensile kev ntxhov siab (teeb meem)
Electrogalvanizing
Lub Cathode Hydrogen Evolution cov tshuaj tiv thaiv tsim 400-600MPA TENENILE ntxhov siab rau saum npoo
Porosity nyob rau hauv txheej (ceev 10 feeb-10⁴ / cmo / cmo ua lub hauv paus ntawm kev qaug zog tawg
3.Qhov yog qhov ntsuas kom ntxiv dag zog rau lub substrate ua ntej plating?
Tua peening:
Steel Feat Hlau Inch 0.3mm, Kev Them Nyiaj 200%, Qhia Txog 200-300MPA Found Kev Nyuaj Siab Compressive
Tuaj yeem offset tensile muaj kev ntxhov siab ntawm HDG alloy txheej, thiab rov muaj zog zog rau 95% ntawm cov khoom siv hauv paus
Laser shock coening
Fais fab kawg 5GW / CM², nthwv dej loj tsim tawm 1.2MM sib sib zog nqus 500MPA Kev Nyuaj Siab Txheej
Qaug zog ntau nce ntxiv ntawm 22% (SAE J1099 Txuj)
4.How nrog nws tom qab plating?
Micro-Arc Oxidation
Tsim kom muaj 10μm tej zaj duab xis ua yeeb yaj kiab ntawm lub galvanized txheej, thiab tawg kev loj hlob da / dn ↓ 50%.
Cov Menyuam Polishing:
20mm INCH Ceramic Menyuam Ceramic Cov Menyuam, 50n Siab, Ntse Roughness Ra txo los ntawm 3.2μm rau 0.4μm
10⁷ Cycles Ua Qaug Ua Qws Ua Quav Ntau nce siab txog 30%.
5.Qhov twg yog qhov kev coj ua zoo tshaj plaws?
High fatagon invenance:
Substrate Txhaj Tshuaj Plua Ntshiab → zinc-txhuas-hlau nplaum txheej (mg ntau dua lossis sib npaug li 5%) → micro-arc oxidation
Qeeb zog muaj zog tuaj yeem ncav cuag 105% ntawm lub substrate
Economical Raus (Tsev Hlau Qauv):
Kub-DIP Galvanizing (NI Kev Hloov Kho) Siv Ntxov Ntxhib → Rolling Ntawm Qhov Tseem Ceeb
Qaug zog tsis muaj zog yog tswj tsis pub dhau 10%
Direct Electrogalvanizing yog nruj me ntsis txwv: nws yuav tsum tau muab tso ua ke nrog cov hydrogen, txwv tsis pub lub neej qaug zog yuav txo qis dua 40%.
