“…For the most part, the tribological examinations are conducted by using POD test equipment. AMCs are primarily controlled by the rate of wear and the coefficient of friction [18][19][20][21]. Discs of steel or cast iron are used to generate friction on the specimen [22].…”

In this study, an AA7075 composite material with a varying weight percentage of silver and zirconium oxide reinforcement is examined in terms of its properties. Reinforcement quantities ranging from 0, 4, 8, 12, and 16 wt % were combined with the matrix using the in-situ technique of stir casting in the field. Tensile, mechanical hardness, and compressive strength were assessed in accordance with the standard. The X-ray diffraction and EDS were utilized to analyze AA7075 composites for the distribution and dispersion of particles. Different input parameters such as load (N), composites (wt %), and velocity (m/s) were used to evaluate wear resistance when using the pin-on-disc method. The wear rate (mm/m) was estimated for every weight percent of reinforced mass loss (g). Optimization methods such as Taguchi and analysis of variance were used to determine the AA7075’s optimal processing parameters and composites that were the most significant. In order to identify the best genetic algorithm results, theoretical and experimental results were evaluated.

“…Nickel, Ni-P, and Ni-B coating applications are generally performed with this method. Due to the previously mentioned features, it is used in almost every field of industry [30]. Variables such as bath composition, bath temperature, and pH have high importance in the formation of the properties of the coating layer obtained in the electroless coating method [31].…”

Çelik alaşımları, akma ve çekme mukavemeti, iyi ısıl iletkenlik, işlenebilirlik, şekillendirilebilirlik, süneklik, manyetik özellikler ve geri dönüştürülebilirlik gibi üstün özelliklerinden dolayı en çok kullanılan mühendislik malzemesi sınıflarından biridir. Avantajlarına ek olarak, çelik, kullanımını sınırlayan iki ana faktörden muzdariptir: aşınma ve korozyon. Aşınma ve korozyon, ayrı ayrı veya bir arada, çeliklerde malzeme kaybına neden olarak endüstriyel üretimde maliyetlerin artmasına neden olur. Ancak uygun yüzey işlemleri ile çeliklerin aşınması ve korozyonu önlenebilir veya minimumda tutulabilir. Uygun yöntemlerle sağlanan korozyon ve aşınma direnci, maliyetleri düşürme potansiyeline sahiptir ve endüstriyel tasarımcılara geniş bir malzeme seçimi yelpazesi sunar. Bu çalışmada çelikler hakkında kısaca bilgi verilmiş ardından çelik malzemelerin aşınma ve korozyona karşı önleyici uygulamaları incelenmiştir. Sıcak daldırma kaplamalar, elektrokimyasal kaplamalar, akımsız kaplamalar, termokimyasal yüzey işlemleri, sol-jel, termal sprey kaplamalar, fiziksel buhar biriktirme, kimyasal buhar biriktirme, gibi yüzey işlemleri ile yüzey işlemlerinin çeliklerin aşınma ve korozyon direnci üzerindeki etkileri hakkında tanımlamalar yapılmıştır. Ayrıca proses parametrelerinin ve yüzey işleminden sonra uygulanan ısıl işlem gibi ardıl işlemlerin çeliklerin korozyon ve aşınma davranışı üzerindeki etkileri sunulmaktadır.

“…Atomic number, cubic structure, theoretical density and electrical conductivity of copper at room temperature are 29, face-centered cubic (FCC), 8.94 gr cm −3 , 100%IACS, respectively [1][2][3][4]. Copper, due to its high electrical and thermal conductivity, good formability property, and relatively lower cost than other materials which have high conductivity, can be used in electrical, marine, aerospace industries [5][6][7][8]. In contrast with these promising properties, the application area of copper is limited because of its low oxidation resistance.…”

In this study, copper powders with dendritic morphology were produced by the electrolysis method, and then silver coating was applied to these powders by an electroless coating method. The bulk samples were fabricated by hot pressing method using different ratios of copper and silver-plated copper powders. The results showed that the electroless silver coating layer provided a strong bond at the particle boundaries of the samples, significantly improving the physical and mechanical properties of the materials. Accordingly, the hardness, tensile strength, electrical and thermal conductivity values of the samples produced from silver-plated dendritic copper particles were determined to be approximately 98 HB, 185 MPa, 102 IACS% and 402 W mK −1 , respectively. In addition, the oxidation resistance of the sample produced from completely silver-coated copper powders is 4 times higher than that of pure copper.
