Bu çalışmada, nikel esaslı alaşım ve nanokompozit kaplamalar elektrokimyasal depolama metodu ile paslanmaz çelik altlık üzerine üretilmiştir. Watts tipi nikel banyosuna bor kaynağı olarak trimetilamin boran (TMAB) ilave edilerek Ni-B alaşım kaplama elde edilmiş, daha sonra buna ilave olarak banyoya titanyum diborür (TiB2) seramik nano parçacıkları ilave edilerek nanokompozit kaplama elde edilmiştir. Elektrolit bileşenlerinin kaplama özelliklerine etkilerini incelemek amacıyla elektrokimyasal, mikrosertlik, korozyon dayanımı ve yüzey morfolojileri açısından analizler yapılmıştır. Yapılan incelemeler sonucunda her banyo bileşeninin morfoloji, sertlik ve korozyon dayanımı gibi özellikleri ciddi miktarda etkilediği görülmektedir. Genel olarak yüzey morfolojiler pürüzsüz olmakla birlikte, nanokompozit kaplamanın yüzeyinin daha kaba olduğu optik resimlerden anlaşılmaktadır. Ana yapıya bor elementi ilavesi mikro sertliği yaklaşık %38 oranında artırırken, TiB2 takviyesiyle birlikte saf nikele göre %140, Ni-B alaşımına göre %75 oranında iyileşme olmasına sebep olmuştur. Bor takviyesi korozyon dayanımını azaltırken, TiB2 takviyesi korozyon dayanımında artışa neden olmuştur.
In this study, nikkel-based alloys and nanocomposite coatings were manufactured on the underground of stainless steel with the electrochemical storage method. The Ni-B alloy coating was obtained by adding trimetylamine boran (TMAB) as a bor source to the Watts type nikel bath, then the nanocomposite coating was obtained by adding titanium diboride (TiB2) ceramic nano particles to the bath. To study the effects of electrolyte components on the covering properties, analyses have been made in terms of electrochemical, microserity, corrosion resistance and surface morphology. The results of the studies show that each bathroom component has a serious impact on its characteristics such as morphology, hardness and corrosion resistance. In general, the surface morphologies are smooth, but it is understood by optical images where the surface of the nanocomposite cover is harder. In addition to the main structure, the bor element adds the micro hardness to approximately 38%, while with the TiB2 supplement, it has resulted in an improvement of 140% compared to the pure nikel, and 75% compared to the Ni-B alloy. While the bor supplement reduces corrosion resistance, the TiB2 supplement has caused increased corrosion resistance.

In order to examine the effects of electrolyte components on coating properties, analyzes were carried out in terms of electrochemical, microhardness, corrosion resistance and surface morphology. As a result of the examinations, it was seen that each bath component has a serious effect on the coating properties such as morphology, hardness and corrosion resistance. In general, although surface morphologies were smooth, it was understood from the optical images that the surface of the nanocomposite coating was more coarser. While the addition of boron element to the main structure increased the microhardness by about 38%, with the TiB2 supplement, it caused 140% improvement over pure nickel and 75% improvement over Ni-B alloy. While boron reinforcement reduced corrosion resistance, TiB2 reinforcement caused an increase in corrosion resistance.
