“…Interestingly enough, C1 had the best wear performance, although its microhardness was lower than that of C2, illustrating that microhardness was not the only factor in improving wear resistance. It is well-known that wear rates are directly influenced by residual stresses [37]. Compared with the wear rates obtained with a load of 10 N and a frequency of 5 Hz, the wear rates for C0 and C2 decreased, while the wear rate for C1 actually increased slightly, when the test conditions were a load of 10 N and a frequency of 10 Hz.…”

Shot peening was used synchronously to improve Fe-based amorphous coating performance by delivering ZrO2 ceramic particles into a low-temperature region of a flame during the high velocity oxygen flame (HVOF) spray process. The coating became denser, and its hardness became higher via the new process. Moreover, the compressive residual stress was induced by shot peening. The results from the dry friction test indicated that the coating’s wear resistance was enhanced obviously. The wear mechanism of coatings with and without shot peening is an abrasive wear combined with an oxidation wear at wear test conditions of a low load and a low frequency. The coating with the best wear resistance did not have the strongest microhardness but had the highest compressive residual stress. The compressive residual stress had a significant positive influence on the wear resistance at a low frequency, while its effect is weakened at a high frequency.

“…Another mechanical factor that can influence the tribological behavior of films certainly exists. Reports have shown that the residual tensile stress retained in the film can reduce the adhesion force . To have a better understanding of the influence of the residual stress on the tribological behavior, small‐angle XRD, as described elsewhere, was used to measure the residual stress in the films, and the results are summarized in Table .…”

For practical application, the functional piezoelectric film in microelectromechanical systems should meet the requirement of physical properties, as well as the mechanical properties. In this article, 0.5Ba(Ti0.8Zr0.2)O3–0.5(Ba0.7Ca0.3)TiO3 (0.5BZT–0.5BCT) thin films with varied properties were prepared on (100) Si substrates via a sol–gel technique at different annealing temperatures. The effects of the annealing temperature on the morphology, piezoelectricity, hardness, and elastic modulus were studied. Particular attention was paid to the surface frictional behavior of films, and the changes in the friction force can be radically explained in terms of differences in the hardness/elastic modulus ratio and the residual stress of films. And, it reveals that the higher ratio of hardness to elastic modulus and tensile residual stress can contribute to a lower friction force for 0.5BZT–0.5BCT film during sling friction.

“…This makes them a good candidate for a wide range of tribological applications. Mo-N coatings are mainly deposited by the magnetron sputtering method [18][19][20]. To form the hexagonal δ-MoN phase, a higher nitrogen pressure and/or a higher energy of particles during coating deposition-fulfilled by the arc evaporation method [21][22][23]-is required.…”
