The energy supply mode of a micro-cathodic arc thruster (μ-CAT) was adjusted based on the charge and discharge characteristics storage element, cathode μ-CAT were studied under different modes. We applied an electrical method to measure μ-CAT, with enhanced intensified coupled device spectrum detector plasma parameters allowing analysis internal logic among parameters, characteristics, mode. me...

A CrN/AlCrN coating was prepared on a carbide substrate and PCB milling cutter by the cathodic arc ion plating technique. The organization, mechanical tribological properties of were studied. performance coated cutters investigated tests. results show that surface is smooth dense without obvious defects. has high hardness, low roughness good bonding strength, presenting excellent properties. sh...

AlCrN coatings, which are characterized by high hardness and good wear resistance, often used for drilling, milling, punching tools. Therefore, the study of behaviour these coatings under cyclic impact loading is essential their optimization. Our previous work has focused on composition microstructure prepared using a cathodic arc deposition system with SCIL® controller that controls average io...

Ejection of macroparticles is an inherent and unavoidable characteristic cold cathode arc discharges. The size the spot's melt pool closely related to emitted particle size, existing studies mostly indicate that motion velocity spots can be heightened primarily by magnetic fields, thereby reducing ejection macroparticles. However, scant consideration has been given avoid fundamental nature spot...

Abstract Tetrahedral amorphous carbon (ta-C) has emerged as an excellent coating material for improving the reliability of application components under high normal loads. Herein, we present results our investigations regarding mechanical and tribological properties a 2-µm-thick multilayer ta-C on high-speed steel substrates. Multilayers composed alternating soft hard layers are fabricated using...

Amorphous hydrogenated and/or nitrogenated carbon films, a-C:H/a-C:N, in overall thickness up to 2 nm are materials of choice as a mechanical and corrosion protection layer of the magnetic media in modern hard disk drive disks. In order to obtain high density and void-free films the sputtering technology has been replaced by different plasma and ion beam deposition techniques. Hydrocarbon gas p...

Two microbial fuel cells with different oxygen supplies in the cathodic chamber were constructed. Electrogenic capabilities of both cells were compared under the same operational conditions. Results showed that binary quadratic equations can express the relationships between chemical oxygen demand degradation rate and chemical oxygen demand loading and between chemical oxygen demand removal rat...

The success of a functional coating is intrinsically linked to the improvement its surface properties, as it that will be in direct contact with environment and mechanical stresses when material used severe wear, fatigue, or corrosion applications. It has been shown, for example, by increasing factors such hardness increase durability coating/substrate system. Consequently, current research on ...
