The present disclosure relates to an FeNiP alloy multilayered steel sheet and a method of manufacturing the same.

Provided is an FeNiP alloy multilayered steel sheet including: an FeNi alloy layer including 30 wt % to 85 wt % of Ni, a remainder Fe, and other inevitable impurities, with respect to 100 wt % as a whole; and an FeP alloy layer including 6 wt % to 12 wt % of P, a remainder Fe, and other inevitable impurities, with respect to 100 wt % as a whole, in which the FeNi alloy layer and the FeP alloy layer are alternately laminated on each other several times.

The present disclosure provides articles comprising a laminate material having a void volume of at least 40%, having a lattice structure comprising a plurality of interconnected struts forming polyhedrons in a series that extends in three dimensions, or both, where the laminate materials have an interface density of at least 2.0 interfaces/micrometer (?m). Also described are methods for forming the same.

A plug-in connector has a press-in body which is coated with a first Ni-containing layer and a second Ni-containing layer. The first and/or the second Ni-containing layer is a nanocrystalline or amorphous layer. The first Ni-containing layer and the second Ni-containing layer have grain sizes of different orders of magnitude. In particular, one of the layers can be microcrystalline and the other can be nanocrystalline or amorphous.

The invention relates to a corrosion protection layer system for metal surfaces, said layer system comprising as the two top most layers: a) a discontinuous nickel-phosphorus layer and b) a chromium layer plated from a trivalent chromium electrolyte solution, as well as to a method of producing such a layer system. The inventive layer system is capable to combine the good corrosion resistance of the nickel-phosphorus layer against sodium chloride with the protective power of the chromium layer from the trivalent plating process against magnesium and calcium salts, especially without the need for any post-treatment.

Power pulsing, such as current pulsing, is used to control the structures of metals and alloys electrodeposited in non-aqueous electrolytes. Using waveforms containing different types of pulses: cathodic, off-time and anodic, internal microstructure, such as grain size, phase composition, phase domain size, phase arrangement or distribution and surface morphologies of the as-deposited alloys can be tailored. Additionally, these alloys exhibit superior macroscopic mechanical properties, such as strength, hardness, ductility and density. Waveform shape methods can produce aluminum alloys that are comparably hard (about 5 GPa and as ductile (about 13% elongation at fracture) as steel yet nearly as light as aluminum; or, stated differently, harder than aluminum alloys, yet lighter than steel, at a similar ductility. AlMn alloys have been made with such strength to weight ratios. Additional properties can be controlled, using the shape of the current waveform.

An electro-chemical plating process begins with supplying a supercritical fluid into an electroplating solution to be deposited, and a bias is applied between a substrate and an electrode, which is located in the electroplating solution. The substrate is placed into the electroplating solution to deposit a material on the substrate.

Coated articles and methods for applying coatings are described. In some cases, the coating can exhibit desirable properties and characteristics such as durability, corrosion resistance, and high conductivity. The articles may be coated, for example, using an electrodeposition process.
