Corrosion Resistant Coatings
Superior corrosion-resistant coatings with added benefits
Corrosion resistant coatings from Electro-Coatings protect metals from corrosion, and give a valuable bonus: extra performance attributes that fight friction, minimize wear and help components maintain precise tolerances. The biggest bonus of all is the application expertise of an Electro-Coatings specialist, ready to sift through multiple options to find the best balance between quality and cost effectiveness.

Improved Corrosion Resistance through Nickel Chrome Plating - Sul-Croloy™
Electro-Coatings' two layer electroplating process which includes sulfamate nickel and hard chrome (Sul-Croloy™) has the ability to greatly improve the corrosion resistance of your base material. Sul-Croloy™ has become a popular coating for hydraulic cylinders and rods or any part working in very corrosive environments. With the high rates of deposition, damaged parts can be repaired in a timely manner.More Info about Sul-Croloy™ Electroplating
Sulfamate Nickel for Corrosion Resistance and Refurbishing Parts
Sulfamate nickel is an ideal option for components which require both corrosion protection and affordable restoration to original specifications. This 99.9% pure nickel coating delivers exceptional corrosion resistance, thanks to its purity, density and highly consistent deposit structure. The most machinable of the nickel coatings Electro-Coatings supplies, it is often used as a build-up coating for resurfacing of worn parts. The electrocatalytic nickel coating process delivers a coating with very good thickness consistency, superior ductility and high temperature resistance.
The excellent thermal transfer capabilities of sulfamate nickel make it ideal for food service applications. It is also popular for restoration of industrial rollers in process machinery that functions in hostile environments. Sulfamate nickel is also frequently used as a base coat to improve the corrosion resistance of chrome plated parts.More Info about Sulfamate Nickel Plating
Kanigen is an Industry Standard for Corrosion Resistance
Since its first use on railroad tank cars in the 1950s, Kanigen® electroless nickel coating has been an industry standard for protection of metal components. Its chemically inert composition and exceptional bond strength make it a trusted protective finish for iron, steel, stainless steel, copper, brass, bronze, aluminum, and their alloys.More Info about Kanigen™ Plating
Corrosion Resistance of Nye-Kote
Coating a metal component with Nye- Kote™ is a great way to protect it from corrosion and oxidation, while adding value and improving performance in the process.
The corrosion-fighting strength of this exclusive electroless nickel coating has been proven over decades of experience offshore and in harsh chemical environments. Its excellent bond strength to any metallic substrate (with an adhesion rating of 300-400 MPa) means the protective coating will stay in place for long term protection.More Info about Nye-Kote™ Electroless Plating
Electro-Coatings' exclusive Electralloy™ process delivers a strong, consistent, protective chromium finish without the component distortion and coating inconsistencies of traditional hard chrome plating.More Info about Electralloy™ Plating
How Zinc Electroplating Protects Against Corrosion
Zinc oxide is a fine white dust that, unlike iron oxide, doesn’t break down the substrate’s surface integrity as it is formed. Much like aluminum or stainless steel oxidation, zinc plating forms a sacrificial barrier around the substrate – it corrodes first, thereby protecting the metal underneath. Protection is typically measured in salt spray performance, such as specified in ASTM B117.
An additional coating, generally chromate, is applied over the zinc for additional corrosion protection. This chromate coating can vary in color among clear, yellow, black and olive drab, meaning different visual appearances can be achieved.More Info about Zinc Electroplating
A High Velocity Combustive Spray Performs Well Against Corrosion
High Velocity Oxy-Fuel (HVOF) coatings fight corrosion by enhancing the surface consistency, hardness and bond strength of many coating types, including tungsten carbide, chrome carbide, nickel alloys, cobalt alloys and various carbon and stainless steels. The HVOF process centers around a spray head that mixes oxygen, a combustible fuel (kerosene, acetylene, propylene and hydrogen) and a powdered friction-reducing coating material. A jetlike nozzle delivers coatings at temperatures of 5-6000o F at velocities beyond 7000 feet per second. HVOF allows coatings to maintain their corrosion resistant properties in high temperature environments, or in applications which must endure mechanical stress from high levels of friction.More Info about HVOF Spray-On Plating
Added Corrosion Resistance with Nickel/Chrome Plating
Nye-Croloy™ is our exclusive nickel/chrome plating solution. Originally developed to protect equipment in oilfield and pumping applications from corrosion, it has evolved into a coating that works in almost any application requiring increased corrosion resistance, including hydraulic cylinders & rods, print cylinders & actuator cylinders, outer drive units and more.More Info about Sul-Croloy™ Electroplating
