Various Processes.
Electroplating
is essentially the process of applying a decorative finish to an
electrically conductive base material. The object that is being plated
is immersed in an electrolyte and connected to an external electrical
current. The metal to be used as the coating is also immersed and
connected to the positive terminal. Electrolysis causes the metal from
the salts in the solution to transfer from the metal source to the
object to be coated. The amount of metal deposited is referred to as
number of microns of plating.
Alocrom 1200
is used for coating all types of aluminium and aluminium alloys when
the desired outcome is for a corrosion resistant and electrical
conductive finish is required. When complete the surface can be painted
or left plain finished. It has a protective gold colour which is
indivisible from the aluminium.
Anodising or Anodizing
is the name for a process used to provide an increased corrosion
resistance of aluminum and aluminum alloys. After cleaning the metal
immersed in a bath of scientifically controlled acids. An electrical
current is applied and oxidation occurs. This results in a thin film of
oxide that is often harder than the unoxidized original metal
underneath this surface. Various colours can be achieved by altering
the thickness of the layer of oxidisation or as in the case of
aluminum, dyes are used to achieve the desired colours.
Chemical Blacking
is provides a highly decorative black finish on most ferrous surfaces.
Chemi-black coating greatly improves both the appearance of the base
object and its resistance to corrosion. Using chemical blacking as a
means of corrosion protection is useful if you do not want to affect
the dimensions of your base object. This process also provides an even
coating to any threads and holes that you are coating.

Electroless
Nickel
process is the production of a nickel alloy, deposited without the use
of an external power source. One major advantage of the Electroless
nickel process is that it provides an even thickness over all surfaces
of the component whatever its shape. This coating is non-toxic which
can be used [for instance] in medical devices, kitchen utensils,
bathroom fittings, work tools and office equipment.
Zinc Plating
is a cost effective means to achieve a high level of corrosion
resistance. By encasing the original object in zinc it is unable to
make contact with the outside elements and thus protects from
corrosion. Zinc provides an excellent even metal distribution and gives
superb levels of wear protection. Zinc Plating can be used as a final
finish or as a protective base coat for later functional or cosmetic
finishes.
Zinc Phosphating
provides corrosion protection and adhesion enhancing for steel,
aluminum, and other metals by building a good base for holding rust
preventive materials and paint bonding.
