Nano-multilayered ZrN-Ag/Mo-S-N film design for stable anti-frictional performance at a wide range of temperatures
Hongbo Ju
Izvirni znanstveni članek
Oznake: DC magnetron sputtering;ZrN‒Ag/Mo‒S‒N multilayer film;tribological properties;tribo-phases;
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 ...

Insights into tribological performances of magnetron-sputtered Si-B-C-N films in air and seawater conditions
Jing Luan, Hongbo Ju
Izvirni znanstveni članek
Oznake: RF magnetron sputtering system;Si-B-C-N composite films;mechanicalproperties;tribological properties;
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 ...

A Generalized Co-HITS Algorithm and Its Application to Bipartite Graphs
Hongbo Deng
Video in druga učna gradiva
Oznake: computer science;web mining
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 ...
