Boron carbide (B 4 C) has been studied under dry sliding conditions for use as a potential finite-life run-in coating. Such a coating has been found to polish its mating surface during dry sliding wear, thereby providing fatigue resistance to the coated part. Employing such run-in coatings requires a complete understanding of the changes that occur in the coating abrasiveness during the polishing process. Therefore, a thorough understanding of the changes in the contact conditions of such a system needs to be obtained. This study presents the role that contact plays in changes of the overall coating abrasiveness. By performing sliding wear experiments using various contact conditions, i.e. ball-on-disc, pin-on-disc and cone-on-disc, we directly investigated the effects of macro-scale contact conditions on the coating abrasiveness. It was found that the rate at which the coating abrasiveness decreased was independent of the macro-scale contact conditions. These findings were further validated by investigating the coating abrasiveness results that were obtained by performing spiral track wear experiments. Through the use of a three-dimensional thermomechanical asperity contact model, it was found that the coating abrasiveness was controlled by the actual micro-scale contact conditions. This study supports the classic Greenwood-Williamson model, which states that the number of micro-scale contacts and the total actual area of contact remains constant for a given load.

“…This is mainly due to the fact that the microstructure and chemistry of these films may vary substantiality depending on the deposition conditions and source gases used, In general, it has been found that the tribological properties of these films are very sensitive to test conditions (such as environment, sliding speed, temperature, etc.) [13][14][15][16][17][18][19]. The presence of some dopants (e. g., silicon] in the structures of DLC films appears to make these films less sensitive to humidity [13].…”

The tribological performance of hydrogen-free DLC films is better in moist air, but hydrogenated DLCS provide much lower ffiction and wear in dry and inert test environments [ 18-?3 ].…”

“…11,12 The average friction coefficient depends strongly on the test duration. [13][14][15] The wear rate correlates with both hardness and with the intrinsic nanometer-scale roughness of the Me-DLC. 13 Such research on friction and sliding characteristics of Me-DLC has already been carried out, [16][17][18][19][20] and the possibility of nonlubricated sliding has been demonstrated.…”

Microstructure and mechanical properties of Ti/AlTiN/Ti-diamondlike carbon composite coatings on steel

Ti/AlTiN/Ti-diamondlike carbon (DLC) composite coatings were deposited by midfrequency magnetron sputtering and Hall ion source-assisted deposition on high-speed steel W 18 Cr 4 V substrates. The coating microstructure and mechanical properties, including hardness, elastic modulus, coefficient of friction, and wear properties were investigated by scanning electron microscopy, Raman spectroscopy, scratch and ball-ondisk friction tests, respectively. Fairly smooth composite coating with strong interfacial adhesion and good mechanical properties was produced. The substrate bias increases sp 3 bonds contents in the DLC layer, thus coating hardness increased from 14 to 24 GPa and elastic modulus from 190 to 230 GPa with the increased substrate bias. Adhesion of interfaces between Ti-DLC and AlTiN layer, AlTiN and the steel substrate decreased with the substrate bias. The coefficient of friction is between 0.10 and 0.15, except when the substrate bias is 500 V, it is 0.2. Composite coating wear resistance increased with the substrate bias.
