ǂA ǂmultilayer film, composed by ZrN-Ag (20 nm) and Mo-S-N (10 nm) layers, combining the intrinsic lubricant characteristics of each layer was deposited using DC magnetron sputtering system, to promote lubrication in a wide-range of temperatures. The results showed that the ZrN-Ag/Mo-S-N multilayer ...

Novel multilayered films were engineered by integrating W▫$_2$▫N and Ag-SiN▫$_x$▫ layers in a multilayer structure to obtain improved hardness and tribological properties. The films were fabricated by alternating magnetron sputtering, depositing 40 nm layers of W▫$_2$▫N with varying thickness of Ag- ...

The Si-B-C-N composite films were deposited using a RF magnetron co-sputtering system with separate SiC and B targets under the Ar+N▫$_2$▫ gas mixture, to optimize self-lubricant behaviors in both air and artificial seawater environments. Results revealed a total X-ray amorphous structure across all ...

In this study, the design of high-entropy alloys (multi-element substitution, Al ▫$^{3+}$▫/La▫$^{3+}$▫/Sb▫$^{3+}$▫/Y▫$^{3+}$▫) was used to increase material entropy and improve heat scattering to further reduce thermal conductivity. Concurrently, Ca▫$^{2+}$▫ ion hole doping was used to improve its e ...

A semi-industrial magnetron sputtering system was employed to deposit a series of W-Ti-N/Ag composite films with varying Ag content, aiming to provide practical parameters for industrial-scale PVD applications. The films were deposited by DC sputtering a W+30 wt%Ti alloy target and an Ag target in a ...

Soft metals have been widely added into ceramic-based films for fully meeting the demanding requirements of green tribological applications. However, the resulting considerable increase of the mechanical strength by adding a soft metal below 5 at.%, which reversed the rule-of-mixture, was still not ...

Achieving simultaneous enhancement of both mechanical and self-lubricating properties by incorporating soft lubricants into nitride films has been a longstanding challenge in the development of solid lubricant materials. This paper introduced a novel approach to overcome this challenge by developing ...

Transition metal dichalcogenide (TMD) coatings have been employed as industrial low friction solid lubricants for machine components operating in vacuum and dry environments. However, their properties degrade in ambient air due to low moisture resistance. Moreover, the pure TMD coatings possess high ...

Recently many data types arising from data mining and Web search applications can be modeled as bipartite graphs. Examples include queries and URLs in query logs, and authors and papers in scientific literature. However, one of the issues is that previous algorithms only consider the content and lin ...
