Enhancing the fretting wear resistance of Zr alloy claddings: A CrTiSiN superlattice coating approach
In this study, the fretting wear behavior of a Zr alloy coated with a CrN/TiSiN multilayer structure was investigated using a lab-scale autoclave fretting apparatus. The multilayer coating exhibited a superlattice architecture consisting of CrN and Ti2N units, with each individual layer having a thickness of approximately 50 nm. The CrTiSiN coating demonstrated significantly improved wear resistance compared to the uncoated Zr alloy. The maximum wear loss of the CrTiSiN coating is 36 %, and no visible cracks were observed in the residual CrTiSiN coating. When fretted against a Zirlo dimple, the wear volume and maximum wear depth of the CrTiSiN coated sample were approximately 21 times and 7.1 times lower than those of the uncoated Zirlo specimen. A tribologically induced three-body layer, composed of wear debris containing Zr, Cr, Ti, and O, was observed on the worn surface. The dominant wear mechanism of the CrTiSiN coating was identified as adhesive wear, with a minor contribution from abrasive wear.
