Special Issue Information

Dear Colleagues,

Coatings or thin films are applications used widely for many goals. There are many materials used as thin films deposited on substrates to improve different characteristics. The area of corrosion and wear protection coatings has been developed very quickly due to the massive economic impact of surface degradation on metallic structures.

Nanocomposite coatings have significant product performance and cost-saving benefits in the global automotive, construction, polymers, solar, glass, oil and gas fields. These types of coatings allow surface functionalization that can improve product longevity, surface strength, and specific properties such as antimicrobial, self-healing, flame retardant, and gas barrier. It is intended to give more emphasis to nanocomposite coating for anti-corrosion and anti-wear applications.

This Special Issue will collect the current research from this broad world of coatings and thin films to assess current trends and predict future developments that will impact the field of materials engineering and tribology. New proposals aim at increasing the level of coatings and thin films engineering material. With this Special Issue, we hope to bring to your attention the latest research, which certainly will be beneficial for the growing community of multidisciplinary researchers.

Molybdenum nitride layers were deposited onto the substrates of high-speed steel using high-power impulse magnetron sputtering. To control the tribological properties of these wear-resistant surfaces, a sophisticated pretreatment of the substrates was performed. Both the topography and the composition of the surfaces were modified on a length scale of a few micrometers before the deposition of MoN. For that purpose, a microembossing technique was applied that used specifically prepared diamond stamps. Compositional variations are realized by an additional deposition of silver. Modifying the properties of the wear-resistant surface via this substrate engineering method allowed a significant reduction in the coefficient of friction, a change of the dominant wear process and a possible lifetime increase. Changing the surface topography led to a reduction of friction and, therefore, to reduced mechanical work supplied to the surface. Occurring wear was reduced accordingly. The introduction of silver further reduced the mechanical energy that was available for the abrasion process and led to an additional increase in the lifetime of the surface. It was concluded that not only the wear volume, but also the relevant wear mechanisms could be influenced via a substrate modification. Full article
