Effect of Hafnium on Nickel-Titanium based Thin Film Coating by DC/RF Magnetron Sputtering Technique
Abstract: Ni-Ti-Hf films as shape memory alloys were successfully prepared by magnetron sputtering technique using individual Ti, Ni and Hf targets. The hafnium content was varied from 6% to 30% and the required film composition was achieved by adjusting the power ratio to the targets. The as-deposited films were amorphous; a post deposition annealing was performed at 700 °C to crystallize the Ni-Ti-Hf films. Structural, compositional and phase-transformation studies were carried …

A Review on Magnetorheological Fluids and its Stabilization Techniques
Abstract: AbstractMagnetorheological fluids are fluids which can alter its physical and rheological properties in response to an external magnetic field. They find many applications in shock absorbers, semi-active dampers, clutches, brakes, haptic actuators and devices. The rheological properties of these fluids can be altered using additives in the fluid composition and hence, the limitations due to settling tendency can be reduced to an extent. Hence, a detailed study on stabilization of …
