Composite materials using natural rubber as the main matrix are popular these days because of wide applications in modern industries. Rubber also have damping properties, energy absorption, and exposure to continuous loads different environmental conditions. In this research, effect temperatures on rubber-epoxy composite with ratios (0%, 10%, 20%, 30%, 40%, 50%) epoxy has been studied. Where co...

in this study, friction stir spot welding (fssw) is applied to join the tial6v4 titanium alloy with 1.5 mm thickness and then the effect of rotational speed and tool dwell time on microstructure and mechanical properties is investigated. in this regard, the speed of the tool rotation was considered as 800, 1000, and 1200 rpm, as well as the tool dwell time was set at 7 and 12s. microstructural ...

The surface properties of alloys can be improved by coating their surfaces and adding a micro-texture. effect on the alloy composite coatings textured has not been addressed in previous studies. In this study, micro-texture was added to WC+Co AlCrN/AlTiSiN coating. influence micro-texture’s geometric parameters its lifespan were studied detail. First, hardness phases various micro-textured anal...
