The current investigation presents the wear-worn surface analysis of a silicon carbide-reinforced brass-based composite synthesized by stir casting. Wear behavior brass pin was analyzed disc tribometer. characterization studies and confirmation elemental composition are investigated through scanning electron microscopy (SEM) energy dispersive spectroscopy (EDS) respectively. worn using atomic f...

The objective of this research is to study the dry sliding wear behaviour of metal surfaces and influences of their surface hardness. The improved hardness of the TiN deposited surface was about 1763 Hv. The worn surface Scanning Electron Microscope (SEM) morphology exhibits the surface damage due to varying wear test parameters. The Electron Dispersive Spectroscopy (EDS) reveals that the mater...

In the current research work synthesis, characterization, mechanical and wear behavior of 5 and 10 wt. % of nano TiO2 particulates reinforced Al7075 alloy composites are inspected. The Al7075 alloy and nano TiO2 particle composites were provided by melt stir system. After the preparation, the prepared composites were analyzed by SEM, EDS, and XRD for inquiring the microstr...

PURPOSE To evaluate the qualitative and quantitative topographic changes in the surface of worn contact lenses (CLs) of different materials using atomic force microscopy (AFM). METHODS The topography of five different CL materials was evaluated with AFM over a surface of 25 microm(2) according to previously published experimental setup. Average roughness (R(a)) and root mean square (Rms) valu...

A new specimen of a fossil tooth the Suidae (Mammalia, Artiodactyla) discovered in upper Miocene Oiso Formation (ca. 8.29-5.57 Ma) Miura Group, Kanagawa Prefecture, Japan, is described. The left m3, and its hypoconulid has broken away. It bunodont, low-crowned, moderately to heavily worn. m3 typical lower molar morphology medium-sized suid, with some furrows on cusps. part containing first two ...

Police body cameras have been a hot topic recently, with controversy surrounding the privacy of officers, the usefulness of the cameras, the policies that should be followed when using footage, and so on [2]. Perhaps one of the most controversial aspects of the police body camera debate is the ability of an officer to disable their camera at will. Reasons ranging from privacy to convenience hav...
