“…Previous studies have shown that counterface materials used in the sliding tests with diamond films can have some effect on friction and wear of these films [45,46]. When sliding against steel surfaces, high friction and severe wear losses can occur on the steel side [47], perhaps due to the relatively high solubility of carbon in iron.…”

Detailed tribological studies on diamond and diamond-like carbon (DLC) films have confirmed that these films are inherently self-lubricating and resistant to abrasive, adhesive and corrosive wear. Because of their high chemical inertness, they are also resistant to corrosion and oxidation (even at elevated temperatures). The combination of such exceptional qualities in these films makes them ideal for a wide range of demanding tribological applications (such as microelectromechanical systems, cutting tools, mechanical seals, magnetic hard disks, etc.). These films, available for more than three decades, have been used extensively for tooling and magnetic hard disk applications. Their potential in other application areas is currently being explored around the world. With the development of new and more robust deposition methods in recent years, it is envisioned that the production of high quality diamond and DLC films will become very cost effective and highly reliable for large-scale applications in the transportation and manufacturing sectors. In this paper, sliding wear mechanisms of diamond and DLC films will be presented. Specifically, it will be shown that, in general, the wear of these films is extremely low (mainly because of their exceptional hardness and low friction characteristics). Specific test conditions established during each sliding test, however, may dramatically affect the wear performance of certain diamond and DLC films. One of the dominant wear mechanisms relates to a phase transformation that is primarily the result of very high mechanical and thermal loadings of sliding contact interfaces. The transformation products (such as disordered graphite) trapped at the sliding interface may transfer to the mating surface and significantly affect friction and wear. This paper describes, in terms of structural and fundamental tribological knowledge, the ideal film microstructures and chemistry, as well as operational conditions under which diamond and DLC films perform the best and provide superlow friction and wear properties in sliding tribological applications.

“…Six different diamond coatings were synthesised by means of high-pressure microwave (MW) plasma-assisted chemical vapour deposition (PACVD) from CH4/H2 gas mixtures on polished polycrystalline a-Sic discs (Cerasiv AG). 27 The size of the discs was 20 mm diameter and 3 mm thickness. Process gas pressure and process gas composition were varied systematically, resulting in different coating morphologies with different roughnesses and grain sizes, shown in Figure 9.…”

The friction and wear behaviour of thin hard coatings, such as TiN and the promising class of C-based coatings (a-C, a-C:H, and diamond for example), are compared under oscillating and reciprocating sliding conditions. The typical effects of test parameters, such as stroke, frequency, normal force, relative humidity and test duration, are described as a basis for the proper selection of test conditions or, conversely, for the selection of suitable coafings for particular practical applications.Friction and wear data from over 1000 vibrating tests using thin hard coatings against 1UUCr6 and against A1203 have been compiled in a database. This allows easy manipulation and comparison of test results. Using selection criteria and filter procedures (e.g., lifetime of coatings, friction limits, and critical wear rate), suitable coating systems for different test conditions can be chosen from the database. The effects of test parameters on friction and wear behaviour and changes have anyway to be known for meaningful tribotesting, as well as for the selection of coatings.
