Abstract
A cooling fixture for thermal spraying includes a rotatable tubular member for supporting a tubular substrate such as for an oxygen sensor. A cooling tube extends from the tubular member into an open end of the substrate so as to delimit an annular channel therein. The other end of the substrate is closed. Air is forced through the cooling tube into the substrate and thence out via the annular channel, to cool the substrate during thermal spray coating of the outside surface.
