Advances in Materials Science and Engineering, Volume 2023, Issue 1, 2023., 2023 The current work investigates the erosion‐corrosion behaviour of thermally sprayed tungsten carbide‐10% nickel (WC‐10% Ni) coatings placed on the AA6061 aluminum alloy. The AA6061 aluminum alloy was coated with tungsten carbide –10% nickel coatings utilising a high‐velocityoxy‐fuel (HVOF) spray method.

Application of Hilbert instantaneous spectrum on improved bolt anchoring quality detection
Engineering Reports, Volume 4, Issue 12, December 2022., 2022 A method utilizing a way to compute the instantaneous frequency curve of the bolt signal is proposed to overcome the phase folding problem existing in the Hilbert transform spectrum. The instantaneous frequency curve of the signal can help accurately identify the reflected signal from the bolt bottom and the position of the defect, thus accurately ...

Advanced Engineering Materials, Volume 24, Issue 9, September 2022., 2022 Shot peening and physical vapor deposition (PVD) coatings provide increased wear resistance to tools of high‐speed steel (HSS). However, high heat input of coating processes leads to the relaxation of previously induced compressive residual stresses and strain‐hardening.

Inner surface peening for long and narrow helical pipe using acoustic cavitation
Materials & Design, 2023 The inner surface peening of helical pipes is highly challenging due to the inaccessibility of the inner surface. To the end, we propose to peen the inner surface by introducing acoustic cavitation inside the pipe. We also provide a theory to account for
