In this study, diamond films are deposited by using hot filament chemical vapor deposition (HFCVD), Nanocrystalline diamond (NCD) coated cemented tungsten carbide (WC-Co) milling tools are characterized, compared with microcrystalline diamond (MCD) and composite diamond coated ones, in terms of morphology with field emission scanning electron microscope (FESEM). Moreover, the diamond coated too...

Wear tends to shorten tool life, reduce component quality. To prevent or postpone the wear of steel forming tools, methods increase resistance, such as increasing material hardness, optimizing carbide distribution and application surface coatings, are often used. However, formation lubricating phases in steels leading anti-attrition is less investigated. The friction behavior three were investi...

Ionic liquid (IL) has various attractive features and attract a great attention as new functional materials for applications. Recently, it has been reported that ILs were applied in scanning electron microscopic (SEM) observation because they do not vaporized even in vacuum condition [1]. Moreover, they can be also used as solvents and supporting films of nanoparticles for transmission electron...

The availability of two-dimensional (2-D) dopant profiling techniques to Silicon Carbide (SiC) pn junction is discussed. We compared the results of scanning capacitance microscopy (SCM), scanning spreading resistance microscopy (SSRM), and secondary electron microscopy (SEM), where the cross-sections of a SiC wafer with n-type epi-layers and highly-doped p and n regions were used. The SSRM curr...

A new experimental method is introduced in order to characterize the mechanical properties of metallic nanowires. An accurate mechanical characterization of nanowires requires simultaneous imaging using scanning electron microscope (SEM) and mechanical testing with an atomic force microscope (AFM). In this study, an AFM is located inside an SEM chamber in order to establish the visibility of th...

A dedicated Scanning Transmission Electron Microscope is ideally coupled with the energy dispersive x-ray and electron energy loss spectroscopies to obtain information about the chemical composition, morphology and electronic structure on the nanoscale. With several signals being available simultaneously with the pass of a subnanometre-sized beam, this instrument can answer questions from a bro...

nano-sized batio3 powders with particular nb concentrations were prepared by rotary- hydrothermal (rh) method. hydrothermal method was used at 180 °c for 5 hours with new ti pressure and the teflon vessel was rotated at a speed of 160 rpm during the hydrothermal reaction. new hydrothermal method was used instead of previous solid state reaction for the system batio3±nb2o3 in high temperature to...

TiO2/graphene nano platelets (GNP) nanocomposite cathodes have been synthesized through a simple ball mill process. TiO2 anatase nanoparticles, around 16 nm in size, were encapsulated in the 2D graphene matrix. The synthesized samples are characterized using x-ray diffraction (XRD), DSC, impedance spectroscopy, and scanning electron microscope (SEM). The graphene nano platelets act not only to ...
