Formik Asit Kullanılarak Elektrokimyasal Yolla Sentezlenen Elmas Benzeri Karbon Filmlerinin Optik, Yüzey ve Mekanik Özelliklerinin İncelenmesi

Abstract

Bu çalışmada elmas-benzeri karbon (EBK) filmleri, indiyum tin oksit (ITO, 180Ω; yarı-karalı durumda)  kaplı cam üzerine elektrolit olarak formik asit (HCOOH) ve deiyonize su karışımı kullanılarak elektrokimyasal biriktirme tekniğiyle elde edildi. Raman spektroskopisi ile bu filmlerin elmas-benzeri karbon karakteri gösterdiği tespit edildi. Filmlerin geçirgenlik yüzdeleri ve soğurma katsayıları UV-GB spektrometre ile hesaplandı. Ayrıca EBK filmlerin yüzey morfolojileri atomik kuvvet mikroskopu ile çalışıldı. Mekaniksel özellikleri (sertlik ve elastik modülü) bir nanoçentme aleti kullanılarak yük-yerdeğiştirme eğrisinden belirlendi. Bu özellikler üzerindeki işlem parametrelerinin etkisi optiksel, yüzey morfolojisi ve mekanik özelliklere ilişkin sonuçlar ile karşılaştırılıp incelendi.

Investigation of Optical, Morphological and Mechanical Properties of Diamond-Like Carbon Films Synthesized by Electrodeposition Technique Using Formic Acid

Abstract

In this study, diamond-like carbon (DLC) films were deposited onto indium tin oxide (ITO)-coated glass substrate electrochemically using formic acid and water as electrolyte. The transmittances and absorbances of films were investigated by UV-Vis spectrometry. Surfaces morphologies of the DLC films were also studied by an atomic force microscopy. The mechanical properties (hardness and elastic modulus) were determined from load-displacement curves using a nanoindentation instrument. The influence of process parameters on these properties were studied and correlated with results concerning optical, topography and mechanical properties.
