“…Ways that speed up the nucleation is regarded to refine the grain size. When the duty cycle increases, a high driven force is provided for transfer of the free ions due to the increase of the average current [39]. In this condition, more ions reduce at the same time and more nucleus crystallized, which lead to finer grain size in the composite coatings.…”

Ni-SiC composite coating was prepared by electrodeposition under the pulse current as an alternative for the environment polluted and human cancerogenic hard chromium plating. The microstructure and tribological performance of the composite coating under different duty cycle were studied. The results showed that the mechanical performance of the Ni-SiC can be optimized by adjusting the pulse duty cycle. With the increase of the duty cycle, the grains were refined and the friction coefficient of the coating decreased. Composite coating obtained under 80 % duty cycle processed the lowest wear volume during the friction and wear test. The effect of duty cycle on the microstructure and tribological performance of the composite coating was discussed. Moreover, the co-deposition mechanism of Ni atoms and the SiC particles under the pulse current were discussed.

“…İlk döngülerdeki hızlı bozulmanın önüne geçilebilmesi amacıyla karbonun elektrokimyasal özellikleri, yapısal modifikasyonlar, tekstür kontrolü, yüzey modifikasyonları ve diğer elementlerle bileşik yapma gibi yöntemlerle geliştirilmeye çalışılmıştır. Bu nedenle, son yıllarda hem taşınabilir elektronik cihazlar hem de elektrikli araçlar için lityum-iyon pillerin en umut verici güç kaynağı olduğu düşünülmektedir [1][2][3][4][5].…”

Li iyon piller günümüzde artan bir ilgi ile taşınabilir elektronik cihazlar için yeniden şarj olabilir piller olarak ana güç kaynağı olmaya başlamışlardır. Ancak ticari pillerde anot malzemesi olarak kullanılan grafitin yeterli performans sergileyememesinden dolayı alternatif arayışları devam etmektedir. Bu nedenle alaşım matrisli kompozit anotların kullanımına yönelik çalışmalar yapılmaktadır. Bu çalışmada da Sn-Cu matrisli KNT takviyeli kompozit anotlar pulse elektro biriktirme ile üretilmiş olup, akım yoğunluğunun etkisi incelenmiştir. Sn-Cu/KNT kompozitleri pirofosfat banyosunda bakır altlık üzerine pulse elektrokompozit kaplama tekniği ile hazırlanmıştır. Üretilen kompozit malzemeler CR2016 buton pilinde anot olarak kullanılarak elektrokimyasal olarak test edildi. Anot malzemelerinin fiziksel ve elektrokimyasal özellikleri çeşitli analiz teknikleri kullanılarak araştırıldı. Sonuçlara göre, kesikli akım (PC) elektrokompozit kaplamada en iyi çevrim performansını 80 mAcm-2 akım yoğunluğu ile üretilen Sn-Cu/KNT kompozit anot göstermiştir.

“…30 These materials have been reinforced with metals to form nanocomposite coatings with improved hardness, wear resistance and corrosion resistance properties. [31][32][33][34] Even though the electrodeposited copper is widely used in the electronics industry for its excellent electrical conductivity, owing to the poor wear resistance and low strength causes failure in the electronic components. Arai et al prepared Cumulti-walled carbon nanotube (MWCNT) composite films by the electrodeposition method and studied its internal stress, electrical conductivity and thermal conductivity.…”

The Cu-Multi-walled carbon nanotubes (MWCNTs) nanocomposite coatings were prepared by the electrodeposition process using MWCNTs in an acid copper plating bath under optimised bath composition and process conditions. The Cu-MWCNTs nanocomposite thin film was characterised for structural, mechanical and anti-corrosion properties. The X-ray diffraction confirmed the crystallite structures and texture of pure copper and Cu-MWCNTs nanocomposite coatings. The field emission scanning electron microscopy showed that the MWCNTs were uniformly distributed in the copper matrix as fine crystallites. The Vickers microhardness test results showed that the microhardness of Cu-MWCNTs nanocomposite coating was much higher than that of the pure copper coating. The electrochemical AC-impedance and Tafel polarisation studies confirmed that the Cu-MWCNTs nanocomposite coating was found to have higher corrosion resistance than the pure copper coating in 3.5% NaCl (w/v) solution.
