DASH 4-NP samples the electroless nickel plating solution, analyzes nickel and pH values, and replenishes automatically. As a result, baths can be maintained continuously at 2-4 of optimum, nickel can be controlled within -0.05 gL, and overall plating rate can usually be increased. It also offers these 12 important advantages
Electroless nickel plating types. cadmium plating is the process of depositing a thin, uniform layer of cadmium onto another substrate, such as a metal or plastic workpiece. chrome plating is a finishing treatment that can be either bright chrome or hard chrome. copper plating is the process of depositing a layer of copper onto a solid metal or plastic workpiece.

Choosing the right plating solution . it isnt always clear which surface plating solution is best for your materials, products or application. some situations call for the extreme durability of hard chrome plating, while others require the intricacy of electroless nickel plating. thanks to our extensive knowledge and experience with both hard ...
Differences between electrolytic vs. electroless nickel plating. electrolytic nickel plating is categorized into two types type i and type ii. type i dull nickel plating uses a sulfamate nickel solution that produces a dull, rough and porous coating which is highly ductile. sulfamate nickel is commonly used for soldering or brazing.
Nickelex is a vastly improved, electroless nickel preparation, formulated specially for semiconductor use. the composition is based upon ions of a nickel complex and hypophosphite together in solution with a catalytic accelerator and a stabilizer. the solution is also buffered at the optimum ph for electroless nickel catalysis.
We apply high precision electroless nickel plating, composite nickel coatings and boron nitride, for industrial applications requiring corrosion protection, high hardness, wear resistance, uniform thickness, and increased dry lubricity on parts from ounces to 300-lbs. typical substrates plated include carbon steel, stainless steel, copper alloys and aluminum alloys.
A local electroless plating process for plastics comprising the steps of coating the nonplating surface portion of a shaped plastic product with a pasty masking composition comprising a polymer and at least one compound selected from the group consisting of a sulfur compound, nitrogen compound and silicon compound roughening the surface portion of the plastics product to be plated and ...
Electroless nickel plating is a focused and elegant process. products simply rest in a proprietary chemical solution to form a seamless layer of nickel. control. electroless nickel gives our engineers total control over the process, with the ability to create smooth, consistent and uniform nickel deposits on parts as large as 50 x ...
Electroless nickel plating en is a process that uses a chemical reaction to co-deposit its nickel-phosphorus coating onto a desired substrate. comparatively, this solution differs from other electroplating processes because it does not require an electricity source to coat the part.
Jul 23, 2020nbsp018332this describes the plating of nickel alloy deposits onto a suitable substrate using a chemical reduction process. these deposits may contain up to 13 phosphorus by weight, or up to 5 by weight boron. the electroless nickel plating process is sometimes simply called en.
Electroless nickel plating is a form of alloy treatment designed to increase resistance and hardness in a metal or plastic. the electroless nickel plating process is simpler than its counterpart electroplating. there is no need to pass an electric current through the chemical bath solution in order to initiate the plating
Electroless plating will not be achieved on complex parts by electroplating. as electroless nickel plating is a chemical process with no current flow involved, the rate of nickel deposition on all areas should be equal, provided uniform solution conditions are maintained. temperature, ph, agitation and solution composition are
For nickel plating, the electrolyte contains soluble nickel salts along with other constituents which will be discussed in the section on chemistry of nickel plating solutions. when dissolved, the nickel salts dissociate into divalent, positively charged nickel ions ni
