Electroless Nickel Plating AST specializes in offering electroless nickel plating (EN Plating) services to extend the longevity of both miniature and large parts exposed to harsh environments. Components finished by our EN plating process have superior resistance to corrosion and rust. With EN plating, which does not involve the use of electric current, we uniformly plate nickel on a variety of substrates with complex geometries.




Electroless Nickel with Teflon Plating Using co-deposited PEN-TUF®/EN and infused EN/PEN-TUF® coatings, we offer Teflon electroless nickel plating services to improve the performance of moving parts used in high speed/moderate load carrying applications. PEN-TUF®/EN is our propriety dry lubrication Teflon coating, which can be applied to a variety of substrates, including stainless steel, aluminum, titanium, copper, and brass. Our PEN-TUF®/EN coatings contain evenly distributed particles of PTFE (polytetrafluroethylene) co-deposited within the nickel phosphorus matrix, offering dual benefits. The lubricity and release properties of PTFE ensure long-life lubrication of parts exposed to consistent wear. For some applications, the use of liquid lubricants can be reduced or ...




Electroless Nickel with Boron Nitride Plating One of our advanced composite plating operations – the electroless nickel with boron nitride plating service - provides composite deposition of both nickel and boron nitride. Designed to satisfy all your protective plating requirements, the boron content in the plating ranges between 0.1 to 6%, which conforms to ASTM B607 specifications. This plating is ideal for parts that require both hardness as well as lubricity. In addition, parts plated with this process can be used in corrosive environments.




Electrolytic Nickel Plating We specialize in bright and dull nickel finishes for a diverse range of engineering as well as corrosion protective applications. Decorative and functional, our nickel finishes have durable mechanical properties that allow them to sustain severe operating conditions. They are ideal for varied metal surfaces, including steel, copper & copper-based alloys, as well as zinc.




Gold Plating AST offers gold plating services for parts made from virtually any substrate ranging from aluminum to steel. Equipped with a number of rack plating and barrel plating equipment, accommodating gold plating, for small as well as large parts, is not a problem for us. As the gold plating process requires a controlled environment, we perform operations in an area with independent air systems, separated from other plating processes.




Silver Plating Silver plating services for parts or components made of virtually all metallic substrates, including steel, aluminum, and copper, are offered at our job shop. Silver plating services are performed with rack line and barrel line equipment in a separate area outfitted with an independent air system. This ensures the controlled environment required for the plating process.




Tin Plating We provide bright as well as matte tin-plating solutions compliant to MIL-T-10727, Type I standards. Our tin plating processes facilitate soldering and improve anti-galling properties in steel, brass, copper, plus numerous other substrates, which otherwise have poor solderability. Our tin plating exhibits excellent corrosion resistance and conductivity in a variety of electrical as well as electronic components, including metallized ceramic chips used in the computer industry.




Plating onto Magnesium Specializing in blister free plating of various tough-to-plate metals, AST offers metal plating services for your magnesium components. Some plating operations that we perform on magnesium parts include electroless nickel, electroless nickel/Teflon, gold, and silver plating. All plating operations can be performed to ASTM and Mil standards of specification. Special pre-treatments required for the plating of magnesium are also performed in-house.




Chromate Conversion Coating Chromate Conversion Coating (also commonly referred to as Chemical Film, Chem Film, Alodine or Iridite) converts the surface properties of the substrate (typically aluminum or magnesium) as compared to plating which applies a coating onto the surface of the substrate. Chromate provides excellent corrosion resistance, is conductive and results in no measureable buildup (0.00001"- 0.00003") on the parts. Chromate coatings are the most widely used coating for corrosion protection of Aluminum and Aluminum alloys minimizing surface oxidation. It is commonly used for an undercoat for paint or adhesive applications due to the excellent bonding properties it provides. Class 1A coatings give maximum corrosion protection with the highest electrical ...




Passivation Passivation is a chemical treatment applied to stainless steel parts to provide resistance to oxidation, rusting and mild chemical attack. The Passivation process removes free iron (ferric material) from the surface of the parts that can be created during finishing operations such as milling, buffing, lapping, cutting, etc. These contaminants create potential sites for corrosion that result in premature deterioration of the component. The acids used for Passivation dissolve much of the alloyed iron on an atomic level right at the surface leaving a chromium and nickel-rich surface. It then creates the formation of a thin oxide film that protects the stainless steel from corrosion.
