Chemical nickel plating: production
|
|
|
|
|
|
|
|
|
Aluminium petrol pump (mass produced). Nickel plating affords double protection from both corrosion and mechanical wear caused by friction. This part has complex shapes: the thickness of the nickel is consistent at all points, even in the smallest internal bores.
|
|
|
|
|
|
|
|
|
Couplings, screws: We plate thin deposits (5µ) for "light" corrosion protection. The parts are produced in a barrel. Perfect uniformity of the coating is achieved.
|
|
|
|
|
|
|
|
|
Coupling for supplying fluid to rotating components: the part requires mechanical and anti-corrosion protection, for this they use 25µ hardened (with hardening heat treatment up to 1000 H Vickers).
|
|
|
|
|
|
|
|
|
High-precision vacuum pump body: they have 50µ nickel plating followed by "diffusion" heat treatment (600°C), the ultimate in corrosion protection...
|
|
|
|
|
|
|
|
|
Small parts in series may, depending on their fragility, be produced in either barrels or as here, on racks.
|
|
|
|
|
|
|
|
|
Here is a "barrel" containing numerous small parts undergoing nickel plating, using either continuous or alternating rotation, depending on their fragility (we offer adjustable speeds).

|
|
|
|
|
Brass parts, with thin nickel plating for "light" corrosion and mechanical protection.
|
|
|
|
|
|
|
|
|
Textile fibre tension rollers: high thickness and hardening treatment limit the abrasive and corrosive impacts of enzymes.
|
|
|
|
|
|
|
|
|
Pump turbine: yet another example of the double protection, against corrosion and wear, achieved with nickel in a single operation.
|
|
|

|
|
|
|
Hydraulic couplings.

The altered colour of the nickel can be seen clearly here after diffusion heat treatment (>600°C), guaranteeing quality and reliability!
|
|
|
|
|
|
|
|
|
These millions of balls are nickel plated to 100µ: as well as corrosion protection, the nickel here provides the ductility necessary for sealed contact on their valve seat.

"Vaned" compressor bodies: corrosion and wear banished simultaneously!
