Tribocorrosion Behavior of Micro/Nanoscale Surface Coatings

Abstract

Wear and corrosion are common issues of material degradation and failure in industrial appliances. Wear is a damaging process that can impact surface contacts and, more specifically, can cause the loss and distortion of material from a surface because of the contacting object’s mechanical action via motion. More wear occurs during the process of corrosion, in which oxide particles or debris are released from the contacting material. These types of wear debris and accumulated oxide particles released during corrosion cause a combination of wear-corrosion processes. Bringing together the fields of tribology and corrosion research, tribocorrosion is a field of study which deals with mechanical and electrochemical interactions between bodies in motion. More specifically, it is the study of mechanisms caused by the combined effects of mechanical stress and chemical/electrochemical interactions with the environment. Tribocorrosion testing methods provide new opportunities for studying the electrochemical nature of corrosion combined with mechanical loading to establish a synergistic relationship between corrosion and wear. To improve tribological, mechanical, and anti-corrosion performances, several surface modification techniques are being applied to develop functional coatings with micro/nano features. This review of the literature explores recent and enlightening research into the tribocorrosive properties of micro/nano coatings. It also looks at recent discussions of the most common experimental methods and some newer, promising experimental methods in tribocorrosion to elucidate their applications in the field of micro/nano coatings.

Evaluation of Corrosive Properties of Hafnium Nitride Coating Over Titanium Screws: An In Vitro Study

“…The development of corrosion-resistant titanium implants is of paramount importance in the medical field. Corrosion poses a significant challenge in medical implants, as it can compromise the structural integrity of the implant and lead to adverse biological reactions in the host organism [ 20 , 21 ]. By addressing the challenges associated with corrosion, researchers and healthcare professionals aim to enhance patient safety, improve implant durability, maintain mechanical stability, preserve aesthetics, and potentially reduce the risk of infections.…”

“…The evaluation process involves a comprehensive set of tests and analyses. Researchers have conducted tests aimed at replicating the corrosive effects of bodily fluids [ 22 ], temperature variations [ 23 ], and mechanical stresses [ 21 , 23 ] to which the implants may be subjected over time. However, the literature lacks enough evidence to substantiate the ideal method for evaluating corrosion resistance.…”

Recent Advances in Bio-Tribology From Joint Lubrication to Medical Implants: A Review

“…The field of wear analysis has been significantly transformed by developments in analytical techniques, which now permit exhaustive and accurate examinations of wear in bio-tribological systems [38,39]. Surface profilometry, scanning electron microscopy, atomic force microscopy, and wear simulation models are methodologies that provide valuable insights into the mechanisms of wear, alterations in surface topography, and progressive material degradation [40][41][42].Methods for in-situ wear testing and wear particle characterization enable the observation of tribological processes occurring at bio-tribological interfaces in real time. The utilisation of microscale and nanoscale imaging technologies in wear studies facilitates the comprehension of intricate interplays that occur between biological tissues and implant materials [43].…”

Influence of TiC Addition on Corrosion and Tribocorrosion Resistance of Cr2Ti-NiAl Electrospark Coatings

“…However, some loaded parts, such as pumps, valves, gears, shafts, propellers, etc., are subjected to intense friction in an aggressive corrosive environment (such as sea water), which leads to removal of the protective oxide film and, as a result, to a decrease in corrosion and wear resistance [4]. The synergistic effect of friction and corrosion is called tribocorrosion, and results in more severe equipment damage and even higher annual maintenance costs [5].…”
