    摘要: A non-aqueous metal catalytic composition includes (a) a silver complex comprising reducible silver ions, (b) an organic phosphite, (c) an oxyazinium salt silver ion photoreducing agent, (d) a hindered pyridine, (e) a photocurable component, a non-curable polymer, or combination of a photocurable component and a non-curable polymer, and (f) a photo sensitizer different from all components (a) through (e) in the non-aqueous metal catalytic composition, in an amount of at least 1 weight %. This non-aqueous metal catalytic composition can be used to form silver metal particles in situ during suitable reducing conditions. The silver metal can be provided in a suitable layer or pattern on a substrate, which can then be subsequently subjected to electroless plating to form electrically-conductive layers or patterns for use in various articles or as touch screen displays in electronic devices.

    摘要: A method for electroplating titanium alloy coating into plastic and carbon foam comprises the steps of activating the given specimen, deposition of electroless nickel and electroplating process of titanium alloy to the surface of the specimen. The electroplating process of electroplating titanium alloy coating includes a direct current method and a pulse plating method. The direct current method characterized by lager sized grains and the pulse plating method characterized by smaller sized grains. The advantages of proposed electroplating processes are: a) low cost, b) very broad applications and c) relatively low number of the process steps. Unique combination of physical, mechanical and chemical properties makes the electroplating methods of titanium coating an attractive technology for medicine, biotechnology, sports, defense, aeronautic, and auto industries.

    摘要: The invention comprises a process of preparing a non-conductive substrate for subsequent metalization. The process replaces the traditional chromic acid etching step with an etching solution comprising a permanganate and a mineral acid. The process also includes a novel activation solution comprising a palladium salt and an amine complexor. The new process of the invention is more environmentally friendly than the traditional chromic acid etching solutions but achieves a comparable result on most non-conductive substrates.

    摘要: The invention includes processes for combined polymer surface treatment and metal deposition. Processes of the invention include forming an aqueous solution containing a metal activator, such as an oxidized species of silver, cobalt, ruthenium, cerium, iron, manganese, nickel, rhodium, or vanadium. The activator can be suitably oxidized to a higher oxidation state electrochemically. Exposing a part to be plated (such as an organic resin, e.g. a printed circuit board substrate) to the solution enables reactive hydroxyl species (e.g. hydroxyl radicals) to be generated and to texture the polymer surface. Such texturing facilitates good plated metal adhesion. As part of this contacting process sufficient time is allowed for both surface texturing to take place and for the oxidized metal activator to adsorb onto said part. The part is then contacted with a reducing agent capable of reducing the metal activator to a lower ionic form, or a lower oxidation state. That reduction can result in the formation of metallic catalytic material over the surface of the part. The reduced metal activator can then function to catalyze the electroless deposition of metal such as copper from solution by contacting the part with the plating solution.
