Çarpan jet elektrot kullanilarak üretilen elektrolitik Nİ kaplamalarda mikroyapinin gelişimi.
Özet
In this study, theimpinging jet cell in whichnickelWattplatingsolutionrecirculatinghas beenused as an experimental
set-up. Intheimpinging jet cell, highspeedjet flow, which is blowedoutfromnozzle, hasbeenimpingedontocathodesurface at
constanttemperetureconditions. Andso, nickelelectroplating has beenachieved. Impinging jet electrode (IJE) techniqueis
one of theconvectivemass transfer techniques.Inthisstudy, IJE technique hasbeenusedbecause of highspeedelectro
platingadvantageandpreferredtoconventionalelectroplatingtechnique. Jet velocity (Vj) anddimensionlessanode-ca
thodedistance (H/d) havebeenchoosed as experimentalparametersandtheeffects of theseparameters on microstructure
of Nidepositsandsurfaceroughnesshavebeenexamined.Inthebeginning of experimentalstudy, thecathodelimiting
currentdensityvalueshavebeenachievedfordifferentvalues of Vjand (H/d). Andthen, Nickelelectroplating hasbeenach
ievedat a constantpotentialvaluecorrespondingtotheselimitingcurrentdensityvalues. Accordingtotheexperimentalresults,
thecathodecurrentdensityincreasesbyincreasingVj, correspondinglythegrainsizes of Nidepositsbecomesmallerand
surfaceroughness of Nidepositsdecreases.Ithas beendeterminedthat, cathodecurrentdensitydecreasesbyincreasing
(H/d), andcorrespondinglythegrainsizesof Nidepositsbecomelarger. Therefore, thesurfaceroughness of Nideposit
has beenincreasedbyincreasing (H/d).
