Unidirectional friction experiments on uniaxially compressed pure Cu powder were performed to clarify how the solid-phase interparticle bonding proceeds during a powder molding method by applying biaxial force, termed as a compression shearing method

We use a Cu/MoS2 composite to provide a new approach to control the consolidation of materials by compression–shearing at room temperature. Cu/MoS2 samples were formed under several shearing distances and the resulting microstructures were observed

Under tribological conditions in aqueous medium, the contact of materials does involve some degradations of materials. Especially friction under small reciprocal displacement, i.e., fretting corrosion, is occurring; this topic has been highlighted si

Formation processes of metal-rich tribofilm on the counterface during sliding against metal/diamondlike-carbon nanocomposite coatings have been investigate. The hybridization between DLC matrix and Cu or Ag provides good electric conductivity to soli

Electrically conductive tribo-coatings (i.e. Ir-DLCs) were developed using a hybrid deposition process, combining RF-PECVD with DC magnetron sputtering of Ir. Pin-on-plate tribotests in reciprocating motion were performed in air on Ir, DLC and Ir-DLC

Six-axis force/torque sensors are increasingly needed in mechanical engineering. Here, we introduce a flexure-based design for such sensors, which solves some of the drawbacks of the existing designs. In particular, it is backlash-free, it can be wir

The incorporation of silicon and oxygen into hydrogenated amorphous carbon (a-C:H) is an effective approach to decrease the dependence of the tribological properties of a-C:H on the environment. Here, we evaluate the effect of hydrogen and oxygen par

Wear. :91-99
Diamond-like carbon coatings (DLC) are promising materials for tribological applications thanks to their ability to reduce friction and wear of mechanical parts. However, their wear mechanism under boundary lubrication and the way they interact with
