The aim of this study is to evaluate the wear and micro hardness a Ti-6Al-4V matrix reinforced with 10% 15% tungsten carbide particle (WCp) composite manufactured using squeeze casting process. Optical microscopy used determine microstructures composite. A pin-on-disc test equipment Vickers at atmospheric temperature were examine behaviour rate, CoF, qualities primed samples. Loads 10 N 80 N, v...

In the current study, the effects of Casimir force and squeeze film damping on pull-in instability and dynamic behavior of electrostatically actuated nano and micro electromechanical systems are investigated separately. Linear elastic membrane theory is used to model the static and dynamic behavior of the system for strip, annular and disk geometries. Squeeze film damping is modeled using nonli...

This paper presents the new route of fabrication H-AlSi24Cu3.8Mg0.8 alloy, assisted by ultrasonic vibration stirring and squeeze casting (UVSS). The primary objective this investigation is to establish tribological characteristics prepared aluminium alloy under dry, lubricated, coated sliding conditions. Oil SAE20W40 used as a lubricant diamond-like carbon (DLC) coating. Under load between 20 N...

In this paper, unsteady two phase simulation of nanofluid flow and heat transfer between moving parallel plates, in presence of the magnetic field is studied. The significant effects of thermophoresis and Brownian motion have been contained in the model of nanofluid flow. The three governing equations are solved simultaneously via Galerkin method (GM). Comparison with other works indicates that...

This paper studies the effects of a constricted squeeze film on the performance of an optical microelectromechanical system accelerometer. Squeeze films are shown to extend the sensor frequency range (bandwidth) in accelerometers without decreasing the mechanical sensitivity by retarding the resonate response. By restricting the venting of a squeeze film, this preferential behavior is observed ...
