... surface morphology of S-Hexagon indicates that severe wear occurs near the leading edge. At the micro level, scattered wear debris and adhesion occur in this area, whereas slight wear such as plowing occurs in the remaining surface area. Thus, the magnitude of contact pressure is much higher near...

... threshold energy of impacting particles at which a transition in erosion rate is noticed for sizes of 200 μ m . It is also observed that the erosion rate increases with the increase in shape factors (aspect ratio and circularity factor). The surface morphology of the eroded surface at impact of 30 deg shows...

... in closed systems. Systematic observations of disloged particles and eroded surface morphology show that the dominant failure mode in cavitation erosion is fatigue. Kenkeramth and Thiruvengadam ( 2 ) analyzed the particles produced by cavitation erosion, and reported that many particles were quite...

...-surface morphology using a molecular-probe scanning method. We found that the film-surface morphology changed periodically with increasing film thickness. The monolayer of a polar lubricant that entirely covers the solid surface provides a flat lubricant surface by exposing its nonpolar backbone outside...

... The growth of grains along (002) preferential orientation was strong for the sample borided at 875°C and least for the sample borided at 950°C; 4 The surface morphologies of the samples borided at 800°C, 875°C, and 950°C seemed to represent consecutive growth stages of the boride layer for the given...

...-coated specimens were tested under a wide range of temperature conditions, from room temperature up to 400 ° C , using a high temperature pin-on-disk tribo-tester. After that, the wear-tested specimens were analyzed using SEM with EDS to characterize the worn surfaces. Morphological changes of the DLC...

... characteristics because these microbearings use the sidewall (110 plane) as a working surface. A special micro wear tester and friction tester were developed. Surface morphologies of new and worn bearing surfaces were studied using SEM. Raman spectroscopy and X-ray photoelectron spectroscopy (XPS) characterized...
