How is the Metallic Coating
Deposited?
Mechanical Plating is
a method of depositing metallic coating onto metal
components by means of the mechanical energy produced by
rotating a barrel or cylinder.
The parts to be coated are
loaded into the barrel with a mixture of glass beads. water,
chemicals and metal powder is added at various stages so that the
combined effect of mechanical energy transferred through the
glass beads and the chemicals, which keep the parts and
metal powder oxide free, this causes the metal to be cold-welded
onto the parts.
Due to the nature of the coatings and
inhibited chemicals used mechanical plating is hydrogen embrittlement free.

7.
Barrel tumbles for
approximately 50mins

8.
