Special Issue Information

Dear colleagues,

We would like to invite you to submit your research work to our Special Issue “Surface Engineering for Friction and Wear Reduction”. The discipline surface engineering includes a broad spectrum of techniques, which can be used to functionalize surfaces and develop a wide range of physical or chemical properties. There are plenty of applications for functionalized surfaces in the automotive, aerospace, power or biomedical sector. The focus of this particular Special Issue will be on approaches of surface engineering to tackle friction and wear. The deposition of wear protective coatings or texturing of materials’ surfaces are prominent means to reduce friction and wear in loaded contacts. Especially laser surface texturing or new honing concepts have proven to be efficient in creating new surface functionalities. Hard coatings like DLC, CrN or TiAlN, amongst others, or 2D materials such as graphene seem to be very promising concerning their tribological characteristics. The synergetic approach to combine the deposition of coatings and surface texturing, though, is also an interesting idea to overcome the respective limitations of each individual approach.

The aim of this Special Issue is to present the latest experimental and computational developments in the research field of surface engineering for friction and wear reduction, through a combination of original research papers and review articles from leading scientists around the world.

In particular, the topics of interest include but are not limited to:

  • Deposition of coatings for wear protection (e.g., PVD, CVD, thermal/plasma spraying);
  • New coating systems and designs for tribological applications;
  • Surface preparation and texturing techniques (e.g., mechanical and chemical polishing, honing, laser surface texturing, micro coining, hammer peening).

In the present study, the influence of experimental variables on the growth characteristics and texture development in chemically vapour deposited α-Al2O3 coatings was investigated. The emphasis was on the effects of H2S. The α-Al2O3 layers were deposited from the AlCl3-H2-CO2-HCl-H2S precursor system onto intermediate Ti(C,N) layers. The substrate was cemented carbide. The coatings were characterized with respect to microstructure and texture using X-ray diffraction, scanning electron microscopy and electron back-scattering diffraction. The observations were unpredictable, suggesting that in addition to the growth rate, H2S strongly affected the texture of the α-Al2O3 coatings. The uncatalyzed α-Al2O3 coatings (H2S = 0) developed (11 2 ¯ 0) texture. With the increment of H2S concentration the texture changed from (11 2 ¯ 0) texture through (10 1 ¯ 0), (10 1 ¯ 2) and (10 1 ¯ 4) textures to (0001) texture. Growth regimes for (11 2 ¯ 0), (10 1 ¯ 0), (10 1 ¯ 2), (10 1 ¯ 4) and (0001) textures were depicted as a function of the H2S/CO2 ratio. Examples of grain-boundary and microstructural manipulation of CVD α-Al2O3 layers by applying texture control were presented. Full article
