چکیده

Aims: To study the effect of metal oxide nanoparticles (MgO, ZrO2, ZnO) on acrylic based soft liner surface properties and FTIR. Materials Methods: Acrylic-based soft-liner specimens were prepared by adding three different concentrations (0.5, 1, 2) %wt ZnO). A disk-shaped with 30mm diameter 3mm thickness for shore (A) hardness test to evaluate modified liner. The roughness samples (10X10X2mm) was tested a profilometer. FTIR analysis conducted chemical reaction that may occur between acrylic-based nanoparticles. Results: there no carried out at concentration- (shore A) increased as concentration in resin. Nanoparticles 1 2% incorporated had lower value. Conclusions: Metal have improved texture liner, while increases.

Analysis of Surface Roughness and Micro-hardness in Roller Burnishing of Aluminum Alloy 6061

Burnishing is a chip-less finishing process, in which a hard roller or ball presses the surface layer of part to perform plastic deformation in the surface layer and produce improved finish, enhanced hardness and compressive residual stresses on the surface of special materials such as Aluminum and Brass. In the following research, the effect of input parameters such as feed rate, cutting speed...
