RSW
(Rotating Single Wire)

Rotating Single Wire RSW, formerly PTWA (Plasma Transferred Wire Arc), is the next evolution of a rotating spray process designed for the coating of internal diameters. Originally developed to coat automotive cylinder bores, Spraywerx is colaborating with GTV in Germany to develop both automotive and non-automotive applications for this commercially proven technology.

RSW technology is a wire based, rotating spray process which combines a twín arc spray process  and an atmospheric plasma spray process. RSW can deposit a coating on an internal or external surface of a cylinder. Internal diameters as small as 2″ (50mm) or as large as 14″ (360 mm) can be coated.

• Particle velocity: 150m/s
• Wire feed rate: 6-10kg/h
• Bond strenght: 45 -55 MPa

A robotic spray booth is available at GTV in Germany for  process prototyping of this technology.
