Polishing silicon carbide against cast iron provides high surface quality (Ra < 1 nm) and a polishing rate of 0.2–0.4 μm h −1. Silicon nitride can also be used as polishing tool and is the preferred tool for polishing silicon carbide.
24/4/2017· Steel is a metal alloy widely used in construction owing to its strength, affordability and hardness. Its various forms consist almost entirely of iron, but also contain the elements carbon, manganese, phosphorous, sulfur, silicon, and sometimes nickel and chromium.
The matrix binds the fiber reinforcement, gives the composite component its shape and determines its surface quality. A composite matrix may be a polymer, ceramic, metal …

By using IR spectroscopy either as an imaging tool or by classifying spectral egories, it has been possible to distinguish between benign and malignant tumors in tissue samples of breast 32-35, colon 22,23,36, lung 37 and prostate 8,30,38,39 along with 4,28,.
Cubic (3C) silicon carbide (SiC) epilayers grown on Si substrates by chemical vapor deposition, characterized using transmission electron microscopy (TEM), high-resolution x-ray diffraction (HRXRD), and Raman spectroscopy, reveal the presence of biaxial in-plane strain. Defect (stacking faults, twins, disloions) distributions revealed by TEM are correlated with peak widths obtained from
