<p>In a thermal spray process, a wire (14) is fed into a flame-jet (20) to heat said wire (14) to the melting point, atomize and projected high velocity the droplets so formed against a surface (28) to buildup a coating of material (24) on the surface (28). The wire (14) is fed into the flame by aligning the cast-plane of the wire (14) with the flame-jet (20) by using a tubular member formed into a circular shape (30) to provide sufficient length to guide wire (14) and to provide the necessary twist amount to the wire (14) to align the cast-plane with the axis of the flame-jet (20).</p> |
