ABSTRACT:
The present invention relates to a thermal barrier coating applied to the inside surface of a catalytic converter and intake pipe between the manifold of an internal combustion engine and the catalytic converter. The catalytic converter and intake pipes are generally formed in two halves to facilitate an effective means by which the thermal barrier coating can be sprayed onto the inside surface by an arc plasma source prior to combining the individual halves of the catalytic converter or intake pipe.
