Lub hardness thiab toughness ntawm lub electroplated cua sov raj yog siab dua li cov ci npib tsib xee txheej.
Nickel-hlau alloy tuaj yeem raug plated ncaj qha rau ntawm cov hlau tsis muaj tooj liab primer, uas ua rau cov txheej txheem yooj yim, tiv thaiv cov txheej txheem cyanide tooj liab plating siv sodium cyanide ua tus neeg sawv cev complex, ua tiav lub hom phiaj ntawm cyanide-dawb electroplating, thiab txhim kho qhov xwm txheej Purify. . Nyob rau tib lub sijhawm, cov hlau tsis muaj teeb meem hauv cov tshuaj nickel-hlau plating tuaj yeem hloov mus rau hauv cov txheej txheem nickel-hlau, uas muaj cov yam ntxwv tsis zoo. Nws hardness thiab toughness yog siab dua li ntawm ci npib tsib xee txheej. Tus kheej nickel-hlau hardness yog HV5688MPa-6669MPa. Vim nws zoo toughness, nws yuav tsis poob tawm txawm tias nws yog plated tawm thiab txiav, thiab cov electroplated npib tsib xee-hlau txheej ntawm lub tiaj phaj tuaj yeem tau txais kev ci ntsa iab. ua ntej.
Electroplating hluav taws xob cua sov tube los tiv thaiv corrosion mloog zoo
Zoo corrosion kuj, ci npib tsib xee-hlau txheej ntxiv rau microporous chrome (siv NI-Fe / satin nickel / chromium, nws txheej chrome yog microporous chrome lossis chrome txheej anode electrolysis), nws cov corrosion kuj zoo dua li ci npib tsib xee ntxiv rau chrome plating txawm zoo dua. Txhawm rau txhawm rau txhim kho kev tiv thaiv corrosion thiab tiv thaiv qhov tshwm sim ntawm cov xim daj, cov nickel-hlau alloy txheej feem ntau yog siv los ua ob txheej npib tsib xee-hlau alloy txheej, uas yog, txheej ntawm nickel-hlau alloy uas muaj {{6 } } feem pua hlau yog thawj plated ntawm cov hlau (xa mus rau high-hlau alloy). Tom qab ntawd ib txheej ntawm nickel-hlau alloy uas muaj hlau -0-5 feem pua (tsuas yog hu ua low-iron alloy) yog plated. Qhov zoo tshaj plaws high hlau alloy nyiaj rau ob feem peb ntawm tag nrho cov thickness ntawm cov hlau txheej. Lub hom phiaj ntawm cov hlau tsis tshua muaj hlau plating ntawm cov hlau tsis tshua muaj hlau yog los tiv thaiv qhov tshwm sim ntawm cov xim daj hauv cov tshuaj corrosion ntawm nickel-hlau alloy plating) thiab ua kom lub peev xwm ntawm cov hlau tsis tshua muaj hlau zoo dua li cov hlau siab. . Cov txheej txheem corrosion tuaj yeem nthuav dav tom qab zoo li ob txheej nickel, yog li txhim kho corrosion kuj.
