The sol-gel synthesis method allows greater control over glass morphology at a relatively low processing temperature (200 °C) in comparison with melt-derived glasses. In present study, phosphate-based glasses with the general formula of (P2O5)55-(CaO)25-(Na2O)10-(TiO2)10 was synthesized via a novel and facil...

In this research, surface composite layers containing nano sized TiB2, Al2O3-TiB2, ZrO2 and CNT particles have been fabricated on Aluminum alloy substrates by friction stir processing. The effects of different processing variables such as number of passes and strengthening particle distribution, hardness, and wear properties of surface nano...
