Electroplated Nickel For Maximum Resistance To Atmospheric Corrosion
What Is Nickel Plating?
Nickel plating is the process of electrolytically depositing a layer of nickel. Parts processed with a bright nickel plating layer maintain their surface appearance and brightness over time.
Why Use Nickel Plating?
Corrosion ResistanceNickel is extremely resistant to atmospheric corrosion, making it an excellent choice as a final layer.
Magnetic PropertiesNickel is also a magnetic material, making it an attractive option when magnetic properties are required.
Longer Service LifeNickel can provide improved wear resistance to soft metals such as copper, resulting in longer service life.
Superior Barrier LayerNickel also provides a superior barrier layer between metals that can experience self diffusion into each other such as copper and tin.
Nickel As A Base Plating Layer
Nickel plating is commonly used as a base plating layer as it provides excellent adhesion between layers and can have a leveling effect on pits or other defects in the base material
High Purity Nickel For Anodes And Cathodes
High purity nickel is used in electronic and aerospace applications, chemical and food processing equipment, for anodes and cathodes, caustics evaporators and heat shields.
Nickel Electroplated Onto Base Metals
Nickel is also electroplated onto base metals when making glass-to-metal seals and also for metal to ceramic seals.
About Nickel Plating Baths
Common nickel plating baths are sulfate, chloride, fluoroborate and sulfamate based. The choice depending upon the desired properties of the deposit. Note: In general, electroplated nickel's corrosion resistance is strictly a function of thickness.
Types Of Plated Nickel Finishes
Depending upon the additives to the nickel plating bath, all chemistries can provide finishes that range from matte through semi-bright to bright in luster. Typically, the brighter the finish, the more stressed the deposit is and the less that can be done as a secondary operation to the deposit.
About Sulfamate Nickel Electroplating
The very low stresses inherent in a Sulfamate Nickel deposit make it ideal for barrier coats. Hi-Tech Plating offers Bright Nickel as well as Sulfamate Nickel. Sulfamate has much better ductility.
When Not To Use Nickel For Plating
Nickel has only fair electrical conductivity (25% that of copper) and heat conductivity. Nickel resists corrosion and most acids, but is attacked by oxidizing acids such as nitric acid.
