1. Hardness thiab hnav tsis kam ntawm chrome plating
Siab Hardness: Lub Chrome Plating Txheej tuaj yeem ncav cuag lub hardness ntawm 400-1200 hv (vickers hardness ua tiav (800-900 hv), txhim kho kev ua kom zoo dua qub.
Hnav Yeem Hluav Taws Xob: Lub Chrome Txheej Txheej Txheem Passivation zaj duab xis thaum sib chwv, txo qhov tsim nyog rau kev sib chwv thiab bearings).
2. Kev cuam tshuam ntawm cov txheej txheem ntawm kev hnav tsis kam
Txheej xob tuab: dog dig chrome plating muaj ib tug tuab ntawm 0.25 {}} 0.5μm, thaum nyuaj chrome plating loj dua los yog sib luag rau 20μm. Thicker txheej ua rau muaj kev tiv thaiv neeg ntev dua-ntev.
Microcack qauv: Chrome plating txheej tshaj 0.5μm ua lub network ntawm microcracks, uas tuaj yeem khaws cov roj nplua nyeem thiab ntxiv kom txo cov kev txhuam txhuam {1} sib piv nrog lwm cov ntaub ntawv
vs. Nickel / zinc plating: Lub hardness ntawm chrome plating (kwv yees
vs. Nyuaj chrome pas nrig: dog dig chrome- plated pas nrig muaj lub zog ntawm 60-80 hrc, thaum nyuaj chrome rods ncav cuag 90-100 teev. Lub zog tawv chrome yog qhov tsim nyog rau siv nyob rau hauv lub zog hnav ib puag ncig (xws li pwm thiab txiav cov cuab yeej).
4. Cov ntaub ntawv thov kev ua tau zoo
Kev Siv Khoom Siv: 45 # steel chrome - plated pas nrig hauv cov txheej txheem xa tawm ntawm lub neej (HV 850+).
Siab - qhov kub thiab txias txheej txheem tsis muaj kev ua kom tiav (xws li} kub sib xyaw (xws li cav piston piston piston).
5. Txoj kev rau kev ua kom zoo hnav tiv thaiv
Multi-layer electroplating: Using a "copper-nickel-chromium" composite coating reduces porosity and improves rust resistance and wear resistance. Cov kev kho deg: Tom qab polishing, kev xav txog ntawm cov txheej chrome yog nce rau 70%, txo kev sib txhuam tawm.
