Metal Coatings
Metal Coatings are used to provide a layer which modifies
the surface properties of the coated substrate into those of the metal applied.
The final piece will then be a composite material exhibiting properties of both
the coating and the metal, therefore, properties generally not achievable by either
of them used alone.
Metal Coatings not
only protect the metal components against moisture, salt spray, oxydation or exposure
to chemicals, they also provide abrasion resistance and chemical protection. In
fact, the coating will provide a durable and corrosion resistant layer while the
core material will provide the ability to bear important loads.
Deposition of metal coatings such as chromium, nickel,
copper, and cadmium, is usually known as metallizing or galvanizing which
can be done either by electroplating or flame spraying. Other methods used for metal coating application are electroless
plating, hot dipping, chemical or ion vapor deposition. |
