Shot Blasting & Heat Treatment
The quality of the electroless nickel plating is dependant on thorough surface preparation. In addition to our chemical cleaning and activation processes, NiTEC also have the facility to shot blast components up to 20 tonnes in weight. Aluminium Oxide 180-220 grit is used to ensure a high standard of surface finish is achieved. The shot blast booth has a capacity of 216m3.
NiTEC also offer a large heat treatment facility. The furnace has a range of 0 - 700°C and is fitted with chart recording equipment, which monitors and the temperature changes of both the furnace and the work. This enables heat treatment profiles to be established for many different requirements. Heat treatment can be used for stress relieving and de-embrittlement as pre- and post-plate treatments. Electroless nickel plating can also be heat treated to alter the hardness of the deposit, to achieve customer requirements for specific applications. More recently, high temperature heat treatment, for sustained periods has been used to diffuse the electroless nickel layer into the steel, to give a slight degree of flexibility to the coating, while not affecting the greatly increased corrosion protection afforded by this type of deposit for marine environments in the offshore oil industry.
The furnace envelope is 1.5 x 1.5 x 2m high and is lined with 316 stainless steel, to minimise particle settlement on the work. Small components can be loaded onto shelves to maximise the heat treatment capacity and minimise the cost of the treatment. The monitoring equipment ensures that the work achieves its required temperature for the required time, eliminating the problem of heat sinks on larger components or mixed load types
NiTEC has two heat treatment furnaces:
- Furnace 1: 1.5 x 1.5 x 2m high
- Furnace 2: 1.7 x 1.7 x 2.2m high
Both are constructed from 316 stainless steel to minimise particles settling on the work.
