POCO materials can be purified
to less than 5 ppm, densified to reduce open porosity
by as much as 80%, or impregnated with resins, oxidation
inhibitors or metals. Surface treatments and coatings
are available to provide a sealed surface, to improve
wear characteristics or to reduce particles.
Some of these additional processes are applied to bulk materials
and others are recommended after final machining.
All POCO grades are available as bulk product, but post processing is normally done on 5-micron grain size materials.
Surface treatments such as pyrolytic coatings should only be done on finished, machined parts. Machining after treatment will expose the graphite substrate.
