There are numerous types of surface coatings available to engineers in order to improve the friction and wear resistance of components. In order to successfully use these coatings in practice, it is important to understand the different types of coatings available, and the factors that control their mechanical and tribological properties. This paper will focus on the application of diamond-like carbon (DLC) coatings in tribological applications. Thus far, DLC coatings have found broad industrial application, particularly in optical and electronic areas. In tribological applications, DLC coatings are now being used successfully as coatings for ball bearings where they decrease the friction coefficient between the ball and race, in shaving applications where they increase the life of razor blades in wet shaving applications, and increasingly in automotive applications such as racing engines and standard production vehicles.The structure and mechanical properties of DLC coatings are dependent on the deposition method and the incorporation of additional elements such as nitrogen, hydrogen, silicon and metal dopants. These additional elements control the hardness of the resultant film, the level of residual stress and the tribological properties. As diamond-like carbon films increasingly become adopted for use in industry, it is important to review the factors that control their 2 of 42 DLC Reviewproperties, and thus, the ultimate performance of these coated components in practical tribological applications.

“…In these graphics, a trend line fitting the punctual results was drawn for each abrasive particle size (both for uncoated and TiAlSiN coated samples), in order to predict the surface wear life. Table 8 presents the wear coefficients calculated based on integrated form [25] of an equation originally proposed by Kassman et al [3]. Attending to the thickness observed, film removed volume was calculated in order to establish the coating wear rate taking in attention the final crater diameter corresponding to each test.…”

“…Depending on the contact geometry, some configurations like pin-on-disk, blockon-ring, and so on, are available. In 1991, Kassman et al referred the micro-abrasion as a new test method to evaluate the abrasion wear behaviour of thin films [3]. Nowadays, the sphere-on-flat configuration is widely employed to test micro-abrasion wear behaviour of thin hard films, using abrasive slurry which is typically constituted by a dispersion of silicon carbide, alumina or diamond particles in distilled water.…”

Ball rotating micro-abrasion tribometers are commonly used to carry out wear tests on thin hard coat-ings. In these tests, different kinds of abrasives were used, as alumina (Al2 O3 ), silicon carbide (SiC) or diamond. In each kind of abrasive, several particle sizes can be used. Some studies were developed in order to evaluate the influence of the abrasive particle shape in the micro-abrasion process. Nevertheless, the particle size was not well correlated with the material removed amount and wear mechanisms. In this work, slurry of SiC abrasive in distilled water was used, with three different particles size. Initial sur-face topography was accessed by atomic force microscopy (AFM). Coating hardness measurements were performed with a micro-hardness tester. In order to evaluate the wear behaviour, a TiAlSiN thin hard film was used. The micro-abrasion tests were carried out with some different durations. The abrasive effect of the SiC particles was observed by scanning electron microscopy (SEM) both in the films (hard material) as in the substrate (soft material), after coating perforation. Wear grooves and removed material rate were compared and discussed.

“…Fixed-ball micro-abrasion wear test was first introduced by Kassman et al [21] and had became one of the widely used methods in determination of abrasive wear resistance of thin hard coatings [22][23]. In this method, a hardened steel ball is rotating by applying pressure either with the help of a load or under its own weight in an abrasive suspension.…”

Wear behavior of four kinds of thermally sprayed coatings on steel tooth drill bits have been investigated by micro-abrasion wear test. The fixed ball micro abrasion wear test was applied for bare substrate and for thermal sprayed substrate of each sample. SiC and Al2O3 abrasive powders with grain size of 5 µm were used in the abrasion experiments. Ball rotational speed values of 140 rpm and applied loads of 1, 2 and 3 N were used. Experimental results show that the wear mechanisms of the coatings are micro-grooving and micro-rolling. Application of the coatings was found to have an influence on the wear mechanism of the samples. The results also indicate that wear resistance of thermally sprayed coatings can be correlated to porosity, hardness, plasticity, toughness, and cohesion properties of the coatings. In addition, wear resistance of the coated samples had increased in accordance with the increasing coating thickness.
