چکیده
Abstract This study demonstrates that magnetron-sputtered NbSe 2 film can be used as a lubricant for space current-carrying sliding contact, which accommodates both metal-like conductivity and MoS -like lubricity. Deposition at low pressure energy is performed to avoid the generation of interference phase 3 . The composition, microstructure, properties films are further tailored by controlling sputtering current. At an appropriate current, changed from amorphous crystalline, maintained dense structure, exhibited excellent comprehensive properties. Compared currently available electrical contact lubricating materials, NbSe2 exhibits significant advantage under combined vacuum conditions. friction coefficient decreases 0.25 0.02, wear life increases more than seven times, electric noise reduces approximately 50%.

متن کاملSynthesis and Characterization of Molybdenum Back Contact Using Direct Current-Magnetron Sputtering for Thin Film Solar Cells
In present work, we report synthesis of molybdenum (Mo) thin films by direct current (DC)-magnetron sputtering method. The structural, optical, morphological, and electrical properties were investigated as a function of target-to-substrate distance. From the results, it is evi d ent that with increase in target-to-substrate distance the thickness of films decreases while its sheet resistance an...

In this study we contribute towards establishing the process-microstructure relationships in thin films grown off-normally by ionized physical vapor deposition. High power impulse magnetron sputtering (HiPIMS) is used at various peak target powers and deposition rates to grow copper (Cu) and chromium (Cr) films from a cathode placed at an angle 90 degrees with respect to the substrate normal. F...
