SMS group brings together two promising technologies: wire arc spraying and an all-digital current/voltage source developed in-house – resulting in the thermal arc spray system PERFECT spray®.

The wire arc system from SMS group comes with several technical advantages – such as, the option of directing the flow on the wire ends well within the supersonic range or of decelerating the gas to subsonic speeds. It has a modular structure and features ceramic internal flow contours, adapted to the relevant coating task. These contours were designed to take account of the gas dynamics and can be adapted to the desired gas volume or mass flow rate.
