Special Issue Information

Dear Colleagues,

Nanostructured materials have been developed for the last few decades, and the unique properties of these materials contribute to the great attention they have received. Nanostructured coatings are now used for many tribological applications, e.g., as anti-wear coatings in bearings, for abrasive wear elements in the automobile and aircrafts industry, as a wear protection coating for high-speed cutting tools, as well as in thermal barrier coatings (TBC) in hot sections of gas turbines, rockets, and space vehicles, and in devices in renewable energy systems. Due to the risk of dynamic loading in these applications, the erosion resistance of these coatings should be investigated. Cavitation degradation is the most undesirable due to the action of dynamic pulses with amplitude up to few GPa, and their duration up to a few ms, or even s. The cavitation erosion resistance of these coatings depends on their structure, including defects and properties, the properties of the substrate material, as well as the cavitation intensity.

The scope of this Special Issue will serve as a forum for papers on the following concepts:

  • Degradation of nanostructured coatings caused by reapeted impacts;
  • Cavitation erosion resistance of monolayer coating;
  • Cavitation erosion resistance of multilayer coatings;
  • The role of coating defects on cavitation degradation;
  • The role of coating structure on cavitation resistance;
  • Influence of cavitation intensity on degradation of nanostructured coating;
  • Cavitation–corrosion resistance of nanostructured coating;
  • Cavitation–slurry erosion reistance of nanostructured coating;
  • Influence of solid particle impact velocity on eroson resistance of nanostructured coating;
  • Degradation nanostructured coating caused by solid particle impacts.

Sand erosion has always been a key threat to the performance and service life of aero-engines. The compressor, the key component installed at the front of the aero-engine, suffers the most from sand erosion, especially compressors serving in deserts. Ceramic hard coating is a traditional way to improve the hardness and wear resistance of cutting and grinding tools. It may also be used to improve the erosion resistance of aero- engine compressor. However, the mechanism of erosion damage is complicated, which may include wear, secondary erosion, anisotropic erosion, impact, and fatigue. Recent research discovered the major problems with ceramic hard coating on aero-engine compressors. In this paper, these following problems are discussed: the design of coating material and structure, the preparation method and technology, the effects of droplets and clusters of coating surface, microstructure and characteristics of interface. The review of the major problems and possible solutions discussed in this paper may contribute to the future research on erosion coating theoretically and practically. Full article

TiN/Ti coatings have great application potential in improving aero-engine server lives in a dusty environment. However, the damage behavior and mechanism of the coating and substrate under high impact speed and multi-direction loading conditions has scarcely been investigated. In this paper, TiN/Ti coatings were deposited on Ti6Al4V alloys by a magnetic filter cathode vacuum arc. Multi-directional impact tests were carried out by a gas gun system at, 45°, 60°, and 90° with a velocity of 330 m/s. The damage behaviors and mechanisms of the TiN/Ti coatings were investigated and revealed by researching the damage morphology, crack propagation, and stress distribution. The results show that plastic deformation occurs both in the coatings and the substrates under high speed impacting. Cracks extend vertically downward in the TiN layer first and are deflected at the Ti layer when the driving force is not enough. Circular cracks and radical cracks are found to form network cracks on the surface of the coating and the shear stress loaded by the particles, which drives cracks’ propagation is the main reason for the peeling off on the coatings.
