Special Issue Information

Dear Colleagues,

During the last three decades, carbon-based coatings have enjoyed a growing interest in several industrial applications. By tuning the carbon sp3-to-sp2 bonding ratio and by alloying the carbon with other elements, the researchers have been able to tailor unique physical, mechanical, and tribological properties in order to satisfy an increased technological demand. Nitrogen doping and other alloying additions like metals, boron, silicon, phosphorous, fluorine, etc., have also been developed to improve their mechanical and tribological properties.

Already in the 1990’s, carbon-based coatings enabled the operation of fuel injectors in gasoline and diesel engines, providing necessary protection against wear, scuffing and other adverse effects of lubricant-lean friction. Nowadays, carbon-based coatings are found in most facets of our daily lives, from the protective films on the hard disks of computers to the lubricious coatings on the blades of a disposable shaving machine. They are used in the chemical, food and packaging industries (valves and cutting hardware), semiconductor processing equipment (wafer handling and mechanical drives of cluster tools), compressors and pumps, and automotive industry (piston rings, camshafts, gears), biomedical applications (stents, heart valves, chirurgical instruments), etc. All the emerging applications of carbon-based coatings are originated in the great variety of crystalline and disordered structures that are possible to obtain by many different deposition techniques.

In this special issue we are requesting original contributions from academic or industrial researchers working on theoretical and/or experimental aspects concerning all kind of carbon-based coatings with improved tribological properties, from basic research to applied (tribological) uses.

Type of Paper: Review
Title: Abrasion Resistant Coatings - A Critical Review
Authors: Xingye Guo, Linmin Wu and Jing Zhang
Affiliation: Department of Mechanical Engineering, Indiana University, Purdue University Indianapolis, Indianapolis, IN 46202, USA
Abstract: Abrasive resistant coatings have been widely used to reduce or eliminate wear, thus extend the lifetime of products. Abrasive resistant coatings can also be used in environments which are not suitable for lubrications. Moreover, abrasive resistant coatings have been employed to strengthen the mechanical properties, such as fracture toughness, hardness, and yield strength. Given recently rapid development in the coatings, this paper provides a critical review of major types of the coatings. The wearing mechanisms, preparation methods and properties of the coatings will also been elaborated.

Title: Microstructure, Properties and Tribological Performance of Magnetron-sputtered V-C coatings
Authors: Michael Stueber and Pantcho Stoyanov
Affiliation: Karlsruhe Institute of Technology, Institute for Applied Materials, Karlsruhe Germany (Stueber), and Fraunhofer IWM, Pfinztal, Germany
Abstract: Transition metal carbides exhibit superior mechanical and tribological properties at a wide range of environmental conditions and contact pressures. More recently, vanadium carbide coatings have been considered for a number of industrial applications due to their high corrosion resistance and mechanical stability at elevated temperatures. However, the friction and wear mechanisms of these coatings have received little attention. The goal of this study is to provide an excessive understanding of the mechanical and microtribological properties of various vanadium carbide-based V-C coatings. The influence of V:C ratio on microstucture formation, mechanical properties and tribological behavior and over a wide range contact pressures is studied in detail. The coatings are prepared using non-reactive d.c. magnetron sputtering with a segmented VC/graphite target, resulting in V:C ratios between 1:1 and 1:3. The microstructure of the coatings changes from single-phase f.c.c. VC1-x to nanocomposites of the type VC1-x/a-C with decreasing V:C ratio. The microhardness of the coatings decreases with decreasing V:C ratio (and is between 3100 HV and 1500 HV for the low and high vanadium concentration respectively). However, reciprocating microtribological tests reveal higher friction values and increased wear with the high vanadium content coatings. This sliding behavior is attributed to differences in the third body formation and velocity accommodation modes.

Title: Mechanical and Tribological Behavior of Carbon-Based Coatings Sliding against PEEK Polymer Pounterfaces

Abstract: Carbon-based coatings are known for their good mechanical and tribological properties. By tuning the C sp3-to-sp2 bonding ratio and by alloying the carbon with other elements, it is possible to tailor hardness, elasticity, friction and wear resistance. Also, polyether-ether-ketone (PEEK) polymers are increasingly used by the industry because of their corrosion resistance, mechanical stability, and self-lubricating ability. Huge amount of data regarding their individual interaction with steel counterfaces is available; however, very little information is found regarding the interaction of both materials.
In this work, we studied mechanical and tribological properties of carbon nitride (CNx) and carbon fluoride (CFx) coatings sliding against PEEK. The coatings were deposited on SKF3-steel balls by high power impulse magnetron sputtering (HiPIMS) using an industrial deposition system CemeCon CC800/9ML. CNx was prepared at room temperature (RT) and 180 °C (HT) by reactive sputtering from C target in a N2/Ar discharge at 400 mPa. CFx was prepared at RT by reactive sputtering from a C target in a CF4/Ar mixture at 400 mPa. PEEK 6 mm-thick unfilled plates were produced via injection molding (GATONE™ 5600). The friction and wear properties were measured by a pin-on-disk device using 6.35 mm-dia coated and uncoated balls against PEEK in dry slide at pressure contacts from 860 to 1240 GPa. Optical and scanning electron microscopy, and EDX spectroscopy were used to observe the wear tracks and analyze the presence and composition of transfer films. A triboindenter TI-950 (Hysitron) was used to measure hardness, elastic modulus, and roughness of the materials.
Our results demonstrate that a RT-CNx coating on a steel counterface sliding against a PEEK polymer improves the tribological behavior of the sliding couple, and also is advantageous due to the coating chemical inertness.

Title: MD Investigation of the Tribology of Axisymmetric UNCD Tips with Carbon-based Substrates

Abstract: Molecular dynamics (MD) simulations that utilize the AIREBO potential were used to examine the friction and wear of power-law shaped tips in sliding contact with carbon-based substrates. The impact of substrate material on tribology was elucidated by comparison of simulations with single-crystal diamond substrates to ultra-nanocrystalline diamond (UNCD) substrates. The impact of tip-shape and roughness on friction and wear were examined by using axi-symmetric tips with power-law profiles of the form.
