ABSTRACT:
A processing system which can provide a continuous assembly-line procedure for placing a catalytic coating on ceramic honeycomb type members embodies the use of a plurality of pressure tight chambers such that each ceramic member can be vacuum treated and then rapidly coated, as well as pressure treated and air blown to effect rapid coating fluid removal and partial drying. After each coating operation, there is controlled drying and high temperature curing. Also, in a preferred controlled system, there is a weighing of each element before and after each coating step to determine an amount of coating retained for comparison with a predetermined standard.
