Every surface treatment has its own advantages and disadvantages, and electroless nickel plating is no exception. It can reduce friction and increase durability, but you should be aware of its limitations.
Thickness
To achieve a uniform surface without pitting, electroless nickel plating requires that the nickel remain an extremely thin layer. It is not possible to achieve a thick coating.
Materials compatibility
Some metals resist oxidation and may not fully attach during the electroless plating process. Others may be incompatible with the chemicals involved. For instance, the procedure used at //www.poeton.co.uk/surface-treatments/plating/electroless-nickel-plating is available for titanium alloys, but not pure titanium.
Hydrogen embrittlement
This is caused by an accumulation of hydrogen atoms during the plating process, potentially causing brittleness and cracking. In general, whilst an electroless nickel coating can improve durability, it is not the strongest surface treatment.
Environmental concerns
Chemicals used in the electroless nickel plating process are often toxic. Every stage from sourcing and manufacture to disposal must be carefully managed to prevent environmental pollution.
Cost
Between the requirement for specialised chemicals and the complex, involved processes involved, electroless nickel plating can be a costly endeavour dependent on professional expertise.
Appearance
Electroless nickel plating does not have the usual appearance of nickel, but instead takes on a light blue shade. Less desirably, the process can result in the deposition of a white powder residue that needs removal.
A full understanding of the limits of electroless nickel plating is essential if you are to make an informed decision about whether to use it in your work.
