Akımsız Nikel esaslı kaplamalar malzemelerin aşınma, sertlik ve korozyon gibi yüzey özelliklerini iyileştirmek için otomotiv, havacılık, savunma ve kimya gibi birçok üretim alanında sıklıkla kullanılmaktadır. Akımsız kaplamalar birçok sektörde ikili Ni-P ve Ni-B kaplamalar olarak anılmaktadır. Birçok sektördeki bu yaygın kullanım, yüzey mühendisliği alanında çoklu alaşımların ve kompozitlerin üretilmesini ve araştırılmasını popüler hale getirmektedir. Alüminyum ise uygun maliyeti, mükemmel ısı iletkenliği, yüksek mukavemet/ağırlık oranı özelliklerine sahip, geri dönüştürülebilir bir malzeme olması nedeniyle endüstride demirden sonra en çok kullanılan malzemelerden biri olmuştur. Alüminyum alaşımlarının bu iyi özelliklerinin yanında düşük aşınma dayanımları ve düşük sertlikleri endüstrideki bazı kullanım alanlarını sınırlamaktadır. Bu çalışma kapsamında, alüminyum altlık üzerine kimyasal indirgeme yöntemi ile Ni-P kaplama banyosuna farklı oranlarda sodyum tungsten içerikleri eklenerek Ni-W-P kaplamalar üretilmiştir. Yapılan çalışmada tungsten oranının kaplamanın mikro yapısına, kaplama kalınlığına, sertliğine ve aşınma özelliklerine etkisi incelenmiştir. Bu amaçla alüminyum alaşımlarının yüzey özelliklerini geliştirmek için bazik hipofosfit banyosu kullanılarak 40, 60, 80 g/L sodyum tungsten içeren Nikel esaslı çoklu alaşım kaplamalar alüminyum altlık yüzeyine indirgenmiştir. Optimum sodyum tungsten oranı yapılan karakterizasyonlar sonunda tespit edilmiştir. Üretilen kaplamaların mikro yapı görüntülerinin incelenmesi için Alan Emisyonlu Taramalı Elektron Mikroskobu (FE-SEM), faz yapılarını belirlemek için X-ışını kırınım (XRD) analizi gerçekleştirilmiştir. Üretilen kaplamaların sertliklerini tespit etmek için mikro sertlik ölçümleri gerçekleştirilirken, aşınma dayanımı ve sürtünme özelliklerini incelemek için ise lineer (reciprocating) aşınma testi gerçekleştirilmiştir. Akımsız kaplama yöntemi ile elde edilen çoklu alaşım kaplamaların karakterizasyon işlemleri sonrası sertlik değerlerinin 525 HV’den 645 HV’ye kadar arttığı görülmüştür. Sürtünme katsayısı ise 40 g/L sodyum tungsten içeren kaplamalarda 0,45 µ değerindeyken, 60 g/L’de bu değer 0,15 µ’a kadar düşmüştür. Ayrıca, aşınma oranı değerleri karşılaştırıldığında ise aşınma dayanımında ise yaklaşık 1.25 katlık bir artış söz konusu olmuştur.

The Effect of Sodium Tungsten Content on Hardness and Wear Properties of Ni-W-P Multiple Alloys Produced by Electroless Coating Method

Electroless Nickel-based coatings are frequently used in many production areas such as automotive, aerospace, defence, and chemistry to improve the surface properties of materials such as wear, hardness, and corrosion. Electroless coatings are known as Ni-P and Ni-B coatings in many industries. This widespread use in many industries makes the production and research of multiple alloys and composites popular in the surface engineering field. On the other hand, aluminium has become one of the most used materials in the industry after iron due to its affordable cost, excellent thermal conductivity, high strength/weight rate properties, and being a recyclable material. In addition to these good properties of aluminium alloys, their low wear resistance and low hardness limit some usage areas in the industry. This study produced Ni-W-P coatings by adding different amounts of sodium tungsten contents to the Ni-P coating bath by chemical reduction method on the aluminium substrate. In the study, the effect of the tungsten ratio on the microstructure of the coating, coating thickness, hardness, and wear properties were investigated. For this purpose, Nickel-based multi-alloy coatings containing 40, 60, 80 g/L sodium tungsten were reduced to the aluminium substrate surface by using a basic hypophosphite bath to improve the surface properties of aluminium alloys. The optimum sodium tungsten ratio was determined at the end of the characterizations. Field Emission Scanning Electron Microscopy (FE-SEM) was used to examine the microstructure images of the produced coatings, and X-ray diffraction (XRD) analysis was performed to determine the phase structures. While microhardness measurements were carried out to determine the hardness of the produced coatings, a linear (reciprocating) wear test was carried out to examine the wear and friction properties. It was observed that the hardness values of the multi-alloy coatings obtained by the electroless coating method increased from 525 HV to 645 HV after the characterization processes. While the coefficient of friction was 0.45 µ in coatings containing 40 g/L sodium tungsten, this value decreased to 0.15 µ at 60 g/L. In addition, when the wear rate values were compared, there was an increase of approximately 1.25 times in the wear resistance.
