![عکس صفحه اول مقاله: Influence of microstructure on the wear mechanism of multilayered Ni coating deposited by ultrasound-assisted electrodeposition Influence of microstructure on the wear mechanism of multilayered Ni coating deposited by ultrasound-assisted electrodeposition](/preview/png/1658279.png)
Multilayered Ni coating, which is a laminated structure of (ordinary Ni layer)/(ultrasonic Ni layer), was obtained by ultrasound-assisted electrodeposition method on 18–8 stainless steel substrates. Its wear property compared with that of ordinary Ni coating. The crystallographic texture and surface morphology of the coatings were analyzed by means of XRD and SEM, respectively. The multilayered Ni coating exhibits higher wear resistance compared to that of the ordinary Ni coating. The wear mechanism of the multilayered Ni coating is the adhesive wear, which is a kind of the so-called micro-area detachment; while that of the ordinary Ni coating consists of the fatigue and adhesive wear due to its columnar microstructure.
► Multilayered microstructure can inhibit the bulk-flaking behavior.
► Compound fatigue and adhesive mechanism for the O-Ni coating
► Adhesive mechanism for the M-Ni coating
