Innovative ways of avoiding heavy plastic deposits all over the world must be designed and implemented via recycling post-used materials by reusing them as new products with better mechanical properties. As a result continuous use different materials, influencing effects on environment economic issues had been problem confronting post-consumer such materials. High-Density Polyethylene (HDPE) po...
Objective(s): Bioactive silicate ceramics have favorable features for applying as off-the-shelf bone and artificial tissue. Calcium silicate can enhance the generation of an immediate bond with host bone without an intervening rough surface in the bone layer. However, the silicate bioceramics have some drawback regarding their mechanical properties and chemical stabilities. Materials and Method...
In this investigation PVD Ti-Cr)N coatings were deposited on hardened and tempered tool steel substrates using reactive arc evaporation. Physical and mechanical properties of coatings such as roughness, thickness, phase composition, hardness and modulus young and coefficient friction were evaluated. Phase compositions were studies by X-ray diffraction method. The surface microstructure and morp...
In this article aging behavior of composite solid propellant was investigated by determining its mechanical properties at elevated temperatures. For this purpose, three HTPB samples with different microstructures were selected and composite solid propellants were prepared based on them keeping similar other components and aging was studied by accelerated method. Mechanical properties were meas...
