“…In water and oil lubricated conditions, the friction coefficient of these coatings ranged from 0.1 to 0.33 [26] and from 0.05 to 0.15 [27] respectively and the values of the wear coefficient were found as ~10 -15 − 10 -16 m 3 N -1 m -1 for both [26,27]. Improvement in the friction behaviour ( = 0.05 − 0.2) was reported for Si-DLC coatings in a wide range of environmental condition including humid air [14,18]. Similar development was found for…”

“…Lubricated test results are not as favourable (1,2,(8)(9)(10). In the vast majority of cases (Table 1), Si-DLC is reported to increase the overall wear of the coating when compared to a similar non-doped (a-C:H) DLCs.…”

“…The main mechanism for reduced friction in Si-DLC contacts is identified as being caused by production of SiOx species. These are often referred to as silicon rich oxide debris (2,4,11,38). This debris represents oxidative destruction and removal of Si within the coating which in turn amplifies wear of the DLC as a whole.…”

Diamond-like Carbon coatings are well-known for their excellent wear and friction reducing properties. Novel DLCs are constantly being developed that further these beneficial characteristics; this is often achieved by incorporating a dopant into the microstructure of the DLC. One dopant that is widely used currently in commercial settings, including F1 car engines, is silicon. Si doping can be, to some extent, regarded as a double-edged sword. This is because, whilst it has been reported as being able to reduce friction in certain environments, this usually comes at the cost of far higher wear than the corresponding un-doped DLC. The fundamental aspects of Si-DLC's friction and wear properties are explored herein with the goal of optimising the coating using fundamental tribochemical knowledge.

“…In the last decade, many working groups reported that several properties of DLC films are improved by doping with a "hetero element" [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. Especially, titanium (Ti)-doped DLC films have been widely investigated because they are expected to improve sliding properties, burning resistance, and oxidation resistance [22][23][24][25][26][27].…”

The effect of irradiation by a hyperthermal-atomic-oxygen beam on hydrogenated titanium-doped diamond-like carbon (hydrogenated Ti-DLC) films, applied as a solid lubricant for equipment used in low-earth orbit was investigated. Unlike the film thickness of hydrogenated non-doped DLC films, that of hydrogenated Ti-DLC films was found to be constant after the films were exposed to atomic oxygen. In addition, bulk composition of the hydrogenated Ti-DLC film stayed constant, and in particular, hydrogen content in the film did not decrease. These results indicate that a hydrogenated Ti-DLC film can keep its low friction properties under vacuum. Surface chemical analysis showed that a titanium-oxide layer is form on the film by exposure to atomic oxygen. The thickness of the titanium oxide layer was estimated to be about 5 nm from the element distribution in the depth direction of the hydrogenated Ti-DLC films. The titanium-oxide OPEN ACCESSMetals 2015, 5 1958 layer was interpreted to protect the bulk film from erosion by hyperthermal atomic oxygen.
