“…Wear is the progressive damage, involving material loss, which occurs on the surface of a component as result of its motion relative to the adjacent working parts (Kato et al, 1999). Polymer materials when reinforced with high modulus fibers yield higher strength; higher stiffness, better toughness, and good dimensional stability thus improve wear resistance of polymer.…”

Since, the material wear is an important phenomenon influencing the functionality of a part, this research was carried with the aims to study the friction and wear behaviour of parts made of ABS composite material by FDM. This study also compare the friction and wear behaviour of ABS composite with the existing acrylonitrile butadiene styrene (ABS) filament of the FDM machine. The experiment was carried out on the pin-on-disk apparatus according to ASTM G99-04 standard under dry sliding condition that were carried out at room temperature. The load was varied (5, 10, 15 and 20 N) at speed of 286 RPM for the run time of 3 and 5 minutes. The results shown that the applied load and run time significantly affect the wear rate, friction force and friction coefficient of the test samples. Based on the experiment, carbon fiber reinforced ABS specimens showed better wear resistance and durability comparing to pure ABS specimens. This research could be useful to develop a better wear resistance component for various fields of applications.

“…[10][11][12][13][14][15][16] More recently, nitrogendoped DLC has gained much attention because of its low friction properties. [17][18][19][20][21] Furthermore, it is experimentally known that the DLC exhibits super-low friction characteristics under very specific conditions. Fontaine and co-workers experimentally performed rubbing tests of DLC against an iron surface under high-vacuum conditions and reported a super-low friction coefficient of 0.002.…”

Fate of methanol molecule sandwiched between hydrogen-terminated diamond-like carbon films by tribochemical reactions: tight-binding quantum chemical molecular dynamics study

Recently, much attention has been given to diamond-like carbon (DLC) as a solid-state lubricant, because it exhibits high resistance to wear, low friction and low abrasion. Experimentally it is reported that gas environments are very important for improving the tribological characteristics of DLC films. Recently one of the authors in the present paper, J.-M. Martin, experimentally observed that the low friction of DLC films is realized under alcohol environments. In the present paper, we aim to clarify the low-friction mechanism of the DLC films under methanol environments by using our tight-binding quantum chemical molecular dynamics method. We constructed the simulation model in which one methanol molecule is sandwiched between two hydrogen-terminated DLC films. Then, we performed sliding simulations of the DLC films. We observed the chemical reaction of the methanol molecule under sliding conditions. The methanol molecule decomposed and then OH-termination of the DLC was realized and the CH3 species was incorporated into the DLC film. We already reported that the OH-terminated DLC film is very effective to achieve good low-friction properties under high pressure conditions, compared to H-terminated DLC films. Here, we suggest that methanol environments are very effective to realize the OH-termination of DLC films which leads to the good low-friction properties.

“…During the deposition of DLC films, elements such as hydrogen and silicon are added in order to control the tribological properties of the DLC film. For example, the tribological properties are improved by adding hydrogen atoms during the fabrication of the DLC film. − Moreover, films containing nitrogen have recently been reported. − However, electronic- and atomic-scale chemical knowledge of the additives is currently not adequate because tribological phenomena are usually investigated on a macroscopic scale.…”
