“…Therefore, due to the positive correlation between the counterface surface hardness and the friction coefficient, the interaction of two ceramic surfaces with higher hardness can result in significant surface wear. This wear is primarily attributed to the increased hardness, and to frictional and abrasive forces [42, 43]. This is the most plausible explanation for the observed wear results.…”

The aim of this study was to evaluate load‐bearing capacity and wear performance of experimental short fiber‐reinforced composite (SFRC) and conventional lithium‐disilicate CAD/CAM fabricated fixed partial dentures (FPDs). Two groups (n = 12/group) of three‐unit CAD/CAM fabricated posterior FPDs were made. The first group used experimental SFRC blocks, and the second group fabricated from lithium‐disilicate (IPS e.max CAD). All FPDs were luted on a zirconia testing jig with dual‐curing resin cement. Half of FPDs per group were quasi‐statically loaded until fracture. The other half experienced cyclic fatigue aging (100.000 cycles, Fmax = 500 N) before loading quasi‐statically until fracture. Fracture mode was examined using SEM. Wear test was performed using 15,000 loading cycles. Both material type and aging had a significant effect on the load‐bearing capacity of FPDs. Experimental SFRC CAD without fatigue aging had significantly the highest load‐bearing capacity (2096 ± 149N). Cyclic fatigue aging decreased the load‐bearing capacity of the SFRC group (1709 ± 188N) but increased it for the lithium‐disilicate group (1546 ± 155N). Wear depth values of SFRC CAD (29.3μm) were significantly lower compared to lithium‐disilicate (54.2μm). Experimental SFRC CAD demonstrated the highest load‐bearing capacity before and after cyclic fatigue aging, and superior wear behavior compared to the control material.

“…Ceramic materials possess high thermal stability, wear resistance and are thus widely used for fabricating components intended for high-temperature loading conditions [1][2][3][4][5] such as sealants, bearings, gaskets, etc., [6]. Ceramics are, as a rule, brittle or quasi-brittle materials of low-surface energy whose shear strength is greatly dependent on contact pressure.…”

Computer modeling of rubbing between two surfaces with microasperities capable of expanding or contracting under conditions of frictional heating (i.e., possessing either positive and negative coefficient of thermal expansion (CTE)) allowed for the identification of wear-and-friction regimes on model ceramic materials. Assuming that no adhesion was involved in the interaction between asperities, two wear regimes—i.e., wear-free and continuous wear—have been revealed in both materials as dependent on the applied normal stress level and sliding velocity. The effect of the normal load on wear rate was similar for both positive and negative thermal expansion ceramics. Sliding velocity has a qualitatively different effect on the wear of materials with either positive or negative thermal expansion. The results indicated that the feasibility of reconstructing wear maps was common for both positive and negative CTE ceramics in terms of dimensionless mechanical and thermophysical characteristics.

“…[3]. In kinematic joints (e.g., cylinder-compression rings, flap track-rollers), high-contact pressure limits the application of conventional anti-wear coatings [4]. One possible exception is fan blades, where thick, hard facing coatings protect the blades' root section and mid-span shrouds [5].…”

This study discusses the effect of a duplex aging + nitriding process on the wear resistance of an aged double-phase titanium alloy, BT22. Nitriding was applied simultaneously with the heat treatment of the alloy, which is advantageous over the conventional heat and surface treatment methods applied to titanium alloys. According to the results, the thickness of the case depth of the nitrided samples was 40–50 μm. Moreover, nitrogen was uniformly dispersed in the substrate, which was indicated by the hardness tests. The average microhardness of the substrate material was 300 HV0.01, while the hardness of the top layer was 1190 HV0.01, which is an almost four-fold increase. The applied duplex treatment substantially affected the wear performance of the tested alloy. For the untreated alloy, the maximum coefficient of friction was 0.8, while in the surface-modified sample, the maximum fluctuations reached 0.6. The abrasive wear process was dominant in the nitrided samples, while delamination and adhesive wear were observed for the untreated specimens. The nitrided alloy exhibited double the wear resistance of the untreated samples. The proposed treatment does not require additional time or energy consumption, providing a substantial technological advantage over conventional methods. Though the alpha case reduces the mechanical performance of titanium, the nitriding of only the component sections intended to withstand friction will have a positive effect.
