“…It can be seen that the content of the α-Al2O3 phase correspondingly increases from the working layer to the technological layer of the coating comparing the ratio of the intensities of reflection (105) α to reflection (200) γ at different depths of the coating. We assumed that this is due to a change in the cooling rate of molten aluminum oxide in the microarc discharge channel [14].…”

“…Thereinto, ST has been proved to be a cost-effective way to change the friction and wear performance of mechanical components through creating periodically distributed macro-/micro units, for example, pillar, pit, groove, and grid, in a geometry or pattern on the target surfaces. [12][13][14][15][16][17][18] Several issues of the wear behavior of textured bearings have been investigated: lubrication, fatigue denting, abrasive wear, spalling, optimization, and so on. Rosenkranz et al 19 fabricated a dot-like pattern (periodicity of 6.5 mm and depth of 1 mm) on the washer surfaces of thrust cylindrical roller bearings (TCRBs, 81212, SAE 52100), and got an 83% reduction in the wear loss of the laserpatterned bearing compared to that of bearings with a ground surface finish.…”

To prolong the serve life of roller element bearings (REB) and improve the reliability of mechanical system, the tribological behavior of the “washers-cage-rollers” system of grooves textured thrust cylindrical roller bearings (TCRB, 81107TN) under dry wear was researched. The pattern parameters include: width of grooves (WOG, 50, 100, and 150 μm), depth of grooves (DPOG, 7, 11, and 15 μm), as well as groove deflection angle (GDA, 0°, 45°, 90°, and 135°). The influence mechanism of grooves on the tribological properties of REBs is discussed. The results show that: As the GDA is 45°, the coefficient of friction (COF) and mass loss of bearing is the lowest among four angles. The average COFs of grooves textured bearings are much higher than that of smooth one, and their mass losses are all lower than that of smooth bearing. The influence of pattern parameters on the surface stresses of grooves textured bearings is weak. In this work, when the WOG is 50 μm and the DPOG is 7 μm, the wear loss of grooves textured bearing is the lowest, reduced by up to 75.6%. This work can provide a valuable reference for the raceway design and optimization of REBs.

“…16 However, the research about the antiwear properties of GCI rings with curve distributed pits in the radial direction (CDPRD) have not been reported, and the influence mechanism of CDPRD on the tribological behavior of GCI samples is not clear yet. [17][18][19][20][21] Therefore, based on previous researches on the anti-wear performance of LDPRD (linear distributed pits in radial direction) textured GCI rings, [22][23][24] a CDPRD pattern was introduced in this work. The thermal behavior of pits textured GCI rings with different key parameters was analyzed using ANSYS/ LS-DYNA module and APDL programming.…”

This study presents the influence of initial deflection angle (IDA) on the tribological properties of gray cast iron (GCI) rings with curve distributed pits in the radial direction (CDPRD). The thermal behavior of pits textured GCI rings with different initial deflection angles (0°, 30°, 45°, 60°, 75°) and fixed deflexional angle of adjacent pits (DAAP, 10°) were researched, through APDL programming. A pin-on-disc wear test rig was used to reveal the anti-wear performance of samples under dry sliding, at a rotating speed of 200 rpm, with a normal load of 70 N. An electronic balance and an optical microscope (OM) were used to obtain their wear losses and worn surfaces, respectively. The results show that: comparing with the smooth GCI ring, there are evident high temperature regions between two adjacent pits groups, called “temperature barrier and separation effect”. Among all textured samples, the von Mise’s stress of IDA45 is the most stable, and its temperature is almost the lowest. The friction coefficient curve and the wear loss of IDA45 are also the lowest, and much lower than the loss of smooth GCI ring, indicating the excellent anti-wear performance. This work can provide a valuable reference for the surface design of journal bearings.
