The present study involves developing a suitable material for using it as a metallic body implant. Mg-alloys is seen as a future bio-absorbable metallic body implant in orthopaedic and other applications. The major problem of using Mg is its high corrosion rate. In this project, we have taken magnesium alloys and have done laser surface texturing. Using texturing different patterns were made. The major purpose of texturing is to improve the corrosion and wear resistance. The specimens were tested for wear and found, that wear rate changes for the textured surface for the increase in load. However, when the load is 3.5 N, the wear behavior was very different from Orchard wear equation. [ABSTRACT FROM AUTHOR]

A highly effective approach to make high-performance microwave absorbers is done by developing porous and lightweight magnetic composites based on carbon. A variety of materials were being investigated for their potential to function effectively as EMI or microwave (MW) shielding materials. In the present scenario, CoFe2O4/Activated Carbon (CF/AC) nanocomposites were made utilizing through one-step polymeric precursor technique. On modifying, the synthesis process allows for a reasonable adjustment of the crystallisation, micromorphology, magnetic characteristics and electromagnetic parameters. The prepared composite has a maximum absorption bandwidth of 8.0 GHz for the CF/AC ratio of 8:10 at a thickness of 3.2mm and a maximum reflection loss of - 13.47 dB for the CF/AC ratio of 10:10 at a thickness of 2mm. It is a comparatively ideal material for absorbing electromagnetic waves. [ABSTRACT FROM AUTHOR]
