Plastic Deformation in an Amorphous Ni-P Coating

Plasticity enhancement in Ni–P amorphous alloy/Ni/Zr-based metallic glass composites with a sandwich structure

“…The yield stress of 0.97 GPa of the Ni coating is in the range of 0.66-1.12 GPa, reported by Tsou et al [28]. Note that the indentation hardness of 6.93 GPa of the Ni-P coating is compatible with 6.3 GPa of Ni-P coating, reported by Shen et al [26]. Fig.…”

“…The elastic modulus of 167.4 GPa of the Ni coating is in the range of 160-240 GPa, reported by Luo et al [25]. The elastic modulus of 99.1 GPa of the Ni-P coating is compatible with 95 GPa of amorphous Ni-P coating, reported by Shen et al [26]. From the following relation [27],…”

Indentation property and corrosion resistance of electroless nickel–phosphorus coatings deposited on austenitic high-Mn TWIP steel

“…Ball indentation with multi-cycles technique can be used to extract the plastic true stress-strain flow curve for any metallic alloy system up to strain 0.15-0.2 [5,9]. The main concern of the A c c e p t e d M a n u s c r i p t 9 current work is to clarify the deformation morphology of the coating and nature of the coating cracking.…”

“…In another work related to the indentation testing of the electroless Ni coating, Shen et al [9] studied the indentation hardness and associated plastic deformation in the as-deposited and asannealed nickel-phosphorus (Ni-P) coatings by indentation testing. Their results showed hat the asdeposited Ni-P coating was deformed appreciably through the formation of shear-band mechanism.…”

Co-existence of homogeneous flow and localized plastic deformation in tension of amorphous Ni–P films on ductile substrate

“…Cu-based MG pillars with tip diameters ranging from 93 to 645 nm under compression, reported by Chen et al [15,16] Several studies have revealed recently that constraining MG films by plastic substrate could suppress the strain localization and early rupture, thereby enhancing its plasticity remarkably [18,19]. Bending [20] and nanoindentation [21] experiments on the glassy films have shown that amorphous coating possesses plastic deformation ability which can improve the fatigue life of crystalline metallic substrates [22].…”
