Single- and dual-cathode DC magnetron sputtering was used to produce TiB 2 coatings and CN x /ZrN multilayers, respectively, with hardness exceeding 40 GPa. The composition, structure, topography, and mechanical properties were determined by various

Two common tribo-failure mechanisms are discussed in this paper.The first mechanism deals with the role of asperity flashtemperature in scuffing (severe adhesive wear) failure. Thesecond mechanism is concerned with the generation andaccumulation of w

New blends of complex lubricants have recently been introduced to help meet the increasing tribological demands being placed on the head-disk interface in hard-disk drives. A20H (Moresco), a hybrid molecule consisting of a perfluoropolyether (PFPE) l

A single-cathode magnetron sputtering system was used to deposit CN x and CN x /TiN coatings onto Si (100) and polished M2 substrates. It was shown that optimum choice of substrate bias and pressure is required to obtain smooth films with maximum har

Lubricant effects in the friction transition from boundary to microelastohydrodynamic lubrication were investigated by using a ballon-flat tribotester at sliding speeds from 0.02 to 0.88 mm/sec. Three lubricants—cyclophosphazine (X-IP), poly-alpha-

α-SiC crystals were implanted with aluminum to a high dose at room temperature or 800 °C. Transmission electron microscopy showed that SiC was amorphized by room temperature implantation but remained crystalline after 800 °C implantation. Crystall

Surface modification of ceramics by ion implantation is a fruitful area of research, giving the prospect of improving their surface-sensitive properties such as oxidation and wear resistance, hardness, and fracture toughness, while retaining the desi

Single-crystal [beta]-SiC was implanted with aluminum to 3.90 x 10[sup 17] ions/cm[sup 2] at 168 keV at 773 K. The resultant compositional and structural characteristics were studied by Rutherford backscattering spectrometry. Auger electron spectrosc

Single crystal β‐SiC was self‐implanted with high‐dose Si and C at 773 K. In situ lattice recovery occurred and SiC remained single crystalline during implantation. Notable structural damage resulted in the implanted region. The residual damag
