“…The specific wear rate decreases at first and then increases with the increase in D. The lowest specific wear rate (about 9 × 10 −9 mm 3 /Nm) appears at D = ±25 µm. The reason is that when the contact region is running in partial slip region or mixed region, the plastic deformation and creep that create a large plastic zone in the center of the contact zone, and the presence of the plastic zone can hinder crack growth and aggravate damage [52,53]. To some extent, the increase in the plastic zone contributes to the strain energy absorption and increases the material toughness in the plastic zone.…”

This paper discusses an in-depth experimental study on the fretting wear behavior of PVDF (polyvinylidene fluoride) piezoelectric thin film against a Si3N4 ceramic sphere under air conditions. A fretting wear device with a ball-on-plate contact configuration was applied. The changes of displacement amplitude, normal force, and applied voltage were taken into account. The friction logs were used to determine the contact state of the PVDF thin film during the fretting test. The 3D topography instrument and scanning electron microscope (SEM) were used to measure the details of the surface morphology and wear volume. The test results of PVDF thin films under different normal force, displacement amplitude, and applied voltage are summarized through the collection and analysis of experimental data. It is shown that the creep and plastic deformation lead to obvious winkles at the contact surface, which may decrease the specific wear rate of PVDF thin films.

“…The diamond/Cu composite shows superior load bearing capacity among all specimens for each wear test. 3D profilogram is a very useful method and has been extensively used to analyze wear surface and related mechanism [44]. The detailed elucidations of wear mechanism about SLD diamond/Cu composite coatings by this technology are currently carried out by us, and the results will be reported in subsequent papers.…”

The supersonic laser deposition (SLD) of diamond/Cu composite powder is studied over a range of laser power. The deposition efficiency, coating microstructure, cohesive/adhesive bonding, phase composition, micro-hardness, and tribological property of the diamond/Cu composite coating are investigated. The results indicate that, as laser power is increased, deposition efficiency initially increases and then declines. The diamond particles distribute uniformly in the composite coating. Due to the increase of velocity ratio and total energy by laser irradiation, the cohesive/adhesive bonding of the composite coating is improved. The composite coating can preserve the phase composition of the origin powders due to the relatively low heat input during the SLD process. Slight oxidation of the Cu powder can be detected in the coatings prepared with high laser power, which has adverse effects on material deposition. The SLD-diamond/Cu composite coating has superior wear-resistance because of low friction coefficient, high micro-hardness, and uniformly distributed diamond particles.

“…Generally, the bearing failure was attributed to the interacted failure factors of bearing, including human factors, equipment factors, material, processing methods and qualities, and service condition. 6 A large number of failure analysis cases in the previous references confirmed that the bearing life was obviously influenced by the material quality (large inclusions, defects), heat treatment quality, 7,8 stress concentration, 9 unreasonable design, 10 improper process, 11 environmental factors, [12][13][14] machined surface quality [15][16][17][18] , and overload. [19][20][21] To the best of our knowledge, there is no systematic and effective failure analysis method for the water pump shaft bearing.…”

The shaft bearing is the key component of water pump and its fatigue failure results in the abnormal operation of the system. However, the failure mechanisms of bearing are still unclear. In this paper, the failure analysis on the engine water pump shaft bearing was carried out by using the measurement of material composition and properties, observation of macro and micro morphologies, and theoretical analysis of fatigue failure. The wear behavior and failure mechanisms were clarified, and the prevention measures was further proposed. The bearing failure reflected from the fracture of bearing cage and serious wear of roller and mandrel. The wear behavior of the mandrel originated from the surface fatigue, and the failure was attributed to the large radial deflection load. Further, the decreased weight of impeller and shaft connector and the increased bearing thickness were recommended to improve the bearing operation.
