Bu çalışmada, St37 çelik altlık üzerine elektrokimyasal olarak depolanan nikel-bor (Ni-B) alaşım ana yapılı ve titanyum diborür (TiB2) takviye parçacık destekli kompozit kaplamaların korozyon davranışları saf nikel ve Ni-B alaşım kaplamalar ile mukayese edilerek incelenmiştir. Üretilen kaplamalar Watts tipi geleneksel nikel banyosunda depolanmıştır. Kaplamaların korozyon dayanımlarının belirlenmesinde açık devre potansiyeli (OCP) grafikleri, Tafel ekstrapolasyon ve elektro empedans spektroskopisi (EIS) yöntemleri kullanılmıştır. Elde edilen OCP grafiklerinde kompozit kaplamanın saf nikel ve Ni-B alaşıma göre korozyon potansiyeli açısından daha pozitif tarafta olduğu görülmektedir. Tafel sonuçlarında ise kompozit kaplamanın korozyon dirençlerinde saf nikele göre %84, Ni-B alaşımına göre ise %87 civarlarında bir iyileşme olduğu belirlenmiştir. EIS sonuçlarında da Tafel sonuçlarında olduğu gibi korozyon dayanımında ciddi bir gelişme olduğu görülmüştür. Elde edilen verilere göre, kompozit kaplamanın korozyon direnç değerlerinin saf nikel ve Ni-B alaşımına kıyasla yaklaşık 4 kat daha iyi olduğu belirlenmiştir.

Determination of Corrosion Resistance of Ni-B/TiB2 Electrodeposited Composite Coatings

Öz

In this study, the corrosion behavior of nickel boride (Ni-B) alloy main structure and titanium diboride (TiB2) reinforced particle supported composite coatings deposited electrochemically on a St37 steel substrate was compared with pure nickel and Ni-B alloy coatings. The coatings produced were stored in a Watts-type conventional nickel bath. Open circuit potential (OCP) graphs, Tafel extrapolation and electro impedance spectroscopy (EIS) methods were used to determine corrosion resistances. In the OCP graphs obtained, it was seen that the composite coating was on the positive side in terms of corrosion potential compared to pure nickel and Ni-B alloy. In the Tafel results, it was determined that the corrosion resistance of the composite coating increased by %84 compared to pure nickel and %87 compared to the Ni-B alloy. EIS results showed a serious improvement in corrosion resistance as in Tafel results. According to the data obtained, it was understood that the corrosion resistance values of the composite coating were approximately 4 times better than pure nickel and Ni-B alloy.
