Hard Nickel Plating

Thanks to our extensive knowledge and experience with both hard chrome plating and electroless nickel plating we can help you choose the right method and plating material to give you the mechanical.

Hard nickel plating.

There s a lot to love about this exceptionally hard nickel coating. Hard electroless nickel plating is a kanigen 9 12 wt electroless nickel deposit on which a heat treatment has been applied. Plating helps protect that component from wear and damage from corrosion increases the performance of that part or component and even increase decrease the conductivity of a part too. Parts to be plated must be clean and free of dirt corrosion and defects before plating can begin.

These elements alter the grain structure of the deposit resulting in a finer grain structure that is more lustrous and more resistant to sliding wear. Electroless nickel plating offers a glossier appearance than electrolytic plating and unlike more conventional nickel electroless plating s yellowish hue fades over time. Just hardness or hardness and appearance. Hard gold plating is formed with the addition of non noble metallic elements alloyed with the gold deposit typically cobalt nickel or iron.

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 along with negatively charged ions. It is the most common version of electroless nickel plating. Using plating for a finish for a wide range of metal machinery and parts has many benefits that are well known. Cold solutions with sodium borohydrate as a reducer provide ni b alloy which is hard but dull and grey in appearance while hot bath with sodium hypophosphite results in ni p alloy.

What to consider and how to choose. In fact electroless nickel coating on steel is definitely harder but this depends on what you are trying to achieve. Once the piece has been prepared it is immersed into an electrolyte. Electroless nickel phosphorus plating is a chemical process that deposits an even layer of nickel phosphorus alloy on the surface of a solid substrate like metal or plastic the process involves dipping the substrate in a water solution containing nickel salt and a phosphorus containing reducing agent usually a hypophosphite salt.

This heat treatment changes the structure of the deposit from an x ray amorphous structure to a crystalline structure. Electroless nickel plating vs. Nickel electroplating is a process of depositing nickel onto a metal part. Some situations call for the extreme durability of hard chrome plating while others require the intricacy of electroless nickel plating.
