Metal nanolaminate coatings are introduced as a new approach in post-weld treatment methods. A Cu/Ni coating is electrodeposited from single citrate bath onto butt-welded tension-tension fatigue specimen. The consists of Ni base layer and 160 alternating Cu layers. specimen tested with stress range close to the yield strength This first study reveals surprisingly high lifetime extensions welded...

In this study, the magnetic properties of Si(100)/X5/(Co0.3/Ni0.5)3/Y5 (X: Pt, Cu and Y: Cu, all thicknesses are nm) multilayers were investigated using ferromagnetic resonance technique (FMR). sample sets layers (buffer, cap, Co) grown by magnetron sputtering while Ni sub-layers molecular beam epitaxy (MBE) at high vacuum. The effective anisotropy is 300 mT when copper used as buffer cap layer...

Ni-C/Ti are suitable for the components of neutron supermirrors with high reflectivity because their excellent optical constant and smoother interfaces compared to Ni/Ti. In this paper, investigate mechanism C doping interface, crystallization, composition a multilayer variable Ni-C thickness, four multilayers were prepared by direct current magnetron sputtering, in which thickness layers was 1...

This paper aims to investigate the diffusion bonding of Ti6Al4V Al2O3. The potential use reactive nanolayered thin films will also be investigated. For this purpose, Ni/Ti multilayer with a 50 nm modulation period were deposited by magnetron sputtering onto base materials. Diffusion experiments performed at 800 °C, under MPa and dwell time 60 min, without interlayers. Microstructural characteri...

High entropy alloy films of AlCoCrFeNi B2-ordered structure are formed during an ultrafast heating process by reactive Ni/Al multilayers. The self-propagating high-temperature reaction occurring in multilayers after ignition represents heat source which is used for the transformation a thin Al/CoFe/CrNi multilayer into single-phase high film. materials design combined thus determines phase form...

We perform first-principles calculations for the three multilayer systems (100)-Co 1 /Cu n , NiCo 2 Ni/Cu n and Co 4 Cu n , and find from a comparison of the results for system 2 and 3 that amplitude and phase of the exchange coupling are sensitive to the magnetic-slab/nonmagnetic-spacer interface. Moreover, we observe that for the system 1 the averaged magnetic moment of the magnetic slab osci...
