Special Issue Information

Dear Colleagues,

It is our pleasure to invite you to submit a manuscript to the forthcoming Special Issue “Tribological Behavior and Mechanical Performance of Coatings and Materials” in Coatings (Open Access Materials Science Journal; Impact Factor 3.236).

Employing coatings is one of the most effective methods to reduce friction and protect contacting surfaces from wear. However, the tribological behavior and mechanical performance of the coatings play an important role in its long service life. Generally, the substrate, the structure and composition of the coating, the surface morphologies and the working conditions significantly affect the tribological performance of the coatings. Therefore, various coatings can be manufactured using different techniques, and they have been applied on various substrates in previous studies, resulting in different characteristics.

This Special Issue focuses on the friction performance, wear resistance (e.g., abrasion, erosion, fretting, etc.), corrosion and oxidation resistance, and mechanical performance of the coatings and materials.

Should you need any further information about this Special Issue, please do not hesitate to contact us.

The roller–shoe mechanism is a classic mechanical assembly with an essential role in motion transmission. Common rail high-pressure pumps are an example of a complex assembly that uses such a mechanism to transform the rotation motion into a translation one. The rolling element of the mechanism is represented by a cylindrical roller. Although it can carry heavy loads due to its design, a proper surface profile could significantly increase the life of the entire mechanism. A better solution can be achieved using a logarithmic profile. The shoe is the second base element of the mechanism. It is a part with an inner cylindrical surface and it is separated from the roller by a thin lubricant film. Considering this, increasing the hardness of the roller–shoe contact surface can be obtained using a suitable coating. The positive results of this coating are highlighted using endurance tests to which high-pressure pumps are subjected. Therefore, the roller profile and the shoe coating represent two directions for improving the contact between the mechanism transmission elements, in terms of wear reduction. The purpose of this paper is to identify a suitable roller profile and to highlight its impact on the shoe coating. Full article

This paper investigates the effect of graphene oxide (GO) particles on the friction reduction and wear resistance of coatings on a Ti-6Al-4V alloy generated using the micro-arc oxidation (MAO) technique. Different concentrations of GO were added in aluminate–phosphate electrolyte. The composition of the MAO coatings was investigated using X-ray diffraction and the energy dispersive spectrum. Measurements of the coating’s thickness, hardness, and roughness have also been conducted. Ball-on-disk friction tests under dry conditions were carried out to reveal the tribological behavior of the MAO coating. The results showed that the coating consisted of Al2TiO5 and γ-Al2O3. The addition of GO greatly reduced the friction coefficient by 25%. The coating with 5 g/L of GO particles exhibited the lowest friction coefficient (reduced from 0.47 to 0.35). Moreover, the coating thickness become thicker (from 10 to 20 μm) with an increase in GO concentration from 0 to 10 g/L. The wear mechanism was revealed via worn surface analysis. This study provides a helpful way to improve the surface wear resistance of titanium alloys. Full article
