摘要:
Disclosed is a method for activating a surface of metals, such as self-passivated metals, and of metal-oxide dissolution, effected using a fluoroanion-containing composition. Also disclosed is an electrochemical cell utilizing an aluminum-containing anode material and a fluoroanion-containing electrolyte, characterized by high efficiency, low corrosion, and optionally mechanical or electrochemical rechargeability. Also disclosed is a process for fusing (welding, soldering etc.) a self-passivated metal at relatively low temperature and ambient atmosphere, and a method for electrodepositing a metal on a self-passivated metal using metal-oxide source.
摘要:
A method is provided for metallization of substrates providing a high adhesion of the deposited metal to the substrate material and thereby forming a durable bond. The method applies novel adhesion promoting agents comprising nanometer-sized oxide particles prior to metallization. The particles are selected from one or more of silica, alumina, titania, zirconia, tin oxide and zinc oxide particles which have at least one attachment group bearing a functional chemical group suitable for binding to the substrate.
摘要:
A method of coating an electroplating rack used for supporting non-conductive substrates during a plating process. The method comprises the steps of contacting at least a portion of the electroplating rack with a plastisol composition, the plastisol composition having dispersed therein an effective amount of an additive; and heating the electroplating rack with the plastisol composition thereon to a suitable temperature and for a sufficient time to cure the plastisol and form a solid insulating coating on the electroplating rack. The coated electroplating rack may then be used for mounting non-conductive substrates for subsequent metallization steps.
摘要:
A method includes providing an aircraft component including a substrate made of composite material and a polymeric matrix; and applying a protective coating made of metallic material to the substrate. The protective coating is applied to the polymeric matrix by an electrolytic deposition process.
摘要:
Embodiments of the present invention include methods of disposing a metallic coating layer comprising a metal in an amorphous and/or fine grain microstructure over at least a portion of a surface of a pyrolytic graphite substrate, the metal comprising Nickel, Iron, a Nickel-Iron Alloy, or any combination thereof, and the grains of the metal being of 1 nm to 10000 nm in size. Embodiments of the invention also encompass the coated pyrolytic graphite articles. The coated substrate exhibits a thermal conductivity not less than the uncoated substrate.
