The sheath formation mechanism is modeled in a four-component collisional
electronegative warm plasma considering the behavior of positive ions by fluid equations …

Magnetic nozzle appears to be a practical solution for prolonged space missions. For
efficient handling of the spaceship, an in-flight solution to customize the thrust from the …

The characteristics of obliquely propagating dust acoustic solitary wave in magnetized dusty
plasma are analysed by considering the plasma to have electrons, two-temperature ions …

To further improve the performance of the coated tools, we investigated the effects of low-
energy nitrogen ion implantation on surface structure and wear resistance for TiC coatings …

Ni-P coating was prepared on 20# steel by electroless deposition. And then, the Ni-P
coating was treated by heat treatment and passivation sequentially to greatly improve its …

Nitriding of steels has been widely used for almost a century. However, insight in two
important precipitating phases for low concentration through-thickness nitriding is still …

This report shows the results obtained researching the flank wearing resistance performed
by the high-speed steel (HSS) burins without any surface treatment (reference substrate) …

The research aim evaluates the wear resistance of inserts for turning of tungsten carbide
(WC), uncoated and coated with titanium nitride through physical vapor deposition (PVD) …
