THERMAL BARRIER CERAMIC COATING can solve
the problem of wear and corrosion problems
in various parts.
Many components are deemed to be worn out
when their surfaces have degraded beyond a
predetermined limit. This limit may vary
from the appearance of minor pitting or
scoring marks in bearing surfaces to the
removal of several millimetres of material
from the bucket of an excavating tool.
Metallic parts which have a ceramic coating
applied can extend the life span of various
components.
However, the useful life of many components,
which are unsuitable to be made from
advanced ceramics, may be extended by
coating with a material tailored to resist
the particular environment in which the
component is working. These include thermal
barrier coatings as used in gas turbines and
on piston crowns in large diesel engines;
low friction and anti-seizure coatings as
used in lubricant free bearings and wear
resistant coatings used for the
treatment of valves in internal combustion
engines.
