...) and sliding distance (600, 900, 1200, 1500, 1800, and 2100 m) at a constant sliding speed of 2 m/s. The microstructure of the composites and the worn surface were examined using a scanning electron microscope. A linear increase in wear-rate was observed with sliding distance up to the transition limit...

... of the samples (B3 sample) as compared to as-cast Al7075 alloy. Tribological examination of composite samples shows that wear-rate enhances with an increase in the content of reinforcement. The wear resistance of sample B3 is highest among all prepared composite samples. Wear debris, grooves, micro-cracks...

...Ajith Kurian Baby; Rajendrakumar P. K.; Deepak Lawrence K. Uncertainty analyses can improve the reliability and validity of the assessment of friction and wear-rate of tribosystems. This work analyses the various sources of uncertainty in the estimation of friction and wear-rate of liner-ring pairs...

... stator vane (VSV) system were investigated through the basic pin-on-disc test and actual shaft-bushing test. Different machine learning (ML) models were established based on the experimental information to predict the coefficient of friction (COF) and wear-rate. The results indicated...

... acted as a potent lubricant. Additionally, the silicon carbide counter-body showed the least specific wear-rate. In terms of wear mechanisms, abrasive marks were observed for the AM samples against boron carbide, while the casted samples exhibited both abrasive marks and tribo oxide films. In similar...

... irradiation. Sliding wear process parameters such as normal load, sliding velocity, and sliding distance are optimized through the Taguchi technique. L9 orthogonal array and signal-to-noise (S/N) analysis are used to obtain the optimum process parameters for wear-rate (WR) as the selected response. After...

.... Fig. 9 Wear track and wear depth on the A-xB composites Wear track and wear depth on the A-xB composites Using the wear depth, the specific wear-rates were calculated for the Ax-B composites and plotted in Fig. 10 . The specific wear-rates range from 10 −2 to 10 −3 mm 3 /N · m, which...

..., covering severely under-aged (SUA) to peak-aged (PA) to severely over-aged (SOA) states. Apart from the hardness and tensile properties, two-body abrasive wear properties are also evaluated for differently aged alloys in terms of wear-rate, coefficient of friction, and roughness of the abraded surfaces...
