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

Öz

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.
