The present investigation focuses on the effect of Cr2AlC MAX phase addition on erosion and oxidation‐induced crack healing behavior of Ni–Mo–Al alloy. For this, Ni–Mo–Al and 20 wt% Cr2AlC‐blended Ni–Mo–Al powders were coated by Air Plasma Spray (APS). For oxidation‐induced crack healing studies, the samples were heat treated at 500, 800, and 1100°C in the air for 5 hours. The heat‐treated samples were analyzed by X‐Ray Diffraction (XRD) analysis, Scanning Electron Microscopy (SEM), and Energy Dispersive Spectroscopy (EDS) for the phases, morphology, and composition. Erosion behavior studies were carried out at 30, 250, 500, 800, and 1000°C temperatures. The average hardness was obtained to be 400 ± 10 HV for Ni–Mo–Al coating and 580 ± 10 HV for 20 wt% Cr2AlC‐blended Ni–Mo–Al coating. The addition of Cr2AlC MAX into Ni–Mo–Al matrix reduces the overall erosion rate and improved the crack healing ability. This was attributed to the presence of in‐situ‐formed Cr7C3 and Al2O3 phases.

“…Otherwise, it is not significant. As is apparent from the table, F U � 89.082 ≫ F 0.05 (4,11), F σ � 16.576 ≫ F 0.05 (4,11), F V � 50.607 ≫ F 0.05 (3,12) indicates that the established regression equations are highly significant. In other words, the rotor speed, feed height, installation angle, and the number of guide plates have significant influence on the average velocity of the particles thrown away from the rotor, the total wear value, and the wear uniformity of the split cone in the sand-making process.…”

During the sand-making process, the wear of the split cone will affect the dynamic balance of the rotor and the sand-making effect of the crusher. This paper focuses on experiments and simulations with the rotor of a vertical shaft impact crusher. A wear model for predicting the wear value of the split cone is established and its effectiveness is verified. The orthogonal test of L 16 4 4 is designed. By using the range analysis method, the influence of the rotor speed, the feed height, the installation angle, and the number of the guide plate on the wear resistance of the split cone are studied. By using the multiple linear regression analysis method, the optimal parameter combination of each factor is obtained. The results of this paper show that the wear resistance of the split cone is the best when the installation angle of the guide plate is 40°, the installation number of the guide plate is 3, the rotor speed is 2800 r/min, and the feed height is 40 mm.

“…Hydraulic mucking, also called hydraulic transport, slurry transport, or slurry pipelining, is widely utilized in dredging [12][13][14][15], drilling, mining, etc., and involves the conveyance of solid particles in a suspension [16][17][18]. During these industrial applications, pipeline wear was found to be a significant limiting factor during the service life of a slurry pipelining system [19][20][21].…”

When a slurry TBM advances in pebble and rock strata, large rock particles are carried in pipelines out of a tunnel by moving slurry. To estimate the wear of horizontally straight slurry discharge pipes, a phenomenological model was proposed that was mainly based on knowledge gained by means of direct and indirect in situ observations. The proposed model applies an equation composed of three variables, namely, the wear rate (λ), the central angle (2α), and the excavated tunnel length (L), to estimate the wear distribution along a pipe’s internal surface. The results indicated that wear mainly occurred on the bottoms of pipes. In addition, linear relationships between the maximum pipe wear amount (δmax) and the excavated tunnel length (L) were found for specific pipes and specified types of ground. The observed wear rates of different pipes in different types of ground had varied constants. The wear rates were higher for pipes in rock ground than for those in a pebble layer. For horizontally straight pipes, the observed wear rates were 0.0045 mm/m in a pebble layer and 0.0212 mm/m in rock ground. Lastly, to improve the proposed model, more field monitoring will be necessary to determine the pipe wear rates in different types of ground in the future.
