WIRE ARC SPRAYINGTHERMAL COATING SOLUTIONS
The right corrosion protection is the alpha and omega when it comes to durability and resistance of the material used. With wire arc spraying solutions from SMS group you benefit from a process characterized by high application rates and low energy consumption.
Wire arc spraying represents a well established thermal spray technology. In the process two metallic wires (feedstock material) are fed into a focus point, were an electric arc melts the wire tips. Droplets are formed and are accelerated into the direction of the substrate by secondary atomization with a high-kinetic gas jet. The atomized particles are form a fine-structured homogenous coating on the substrate, with excellent mechanical properties.
SMS group provides individual solutions to meet your special requirements: It is possible to process almost all metallic materials which are in wire form. SMS PERFECT spray® technology feature the option of separately controlled wire feeds whereby different cathode- and anode-side materials can be combined to produce alloys and pseudo-alloys in the process – for example a combination of steel and nickel or aluminum and copper.
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® − consisting of 3 main components:
Almost all metal materials that can be supplied in wire form can be processed. Thanks to the option of separately controlled wire feed rates, users are also able to process different materials on the cathode and anode sides, allowing alloys or pseudo-alloys to be produced in the process (e.g. combination of steel and nickel, or aluminum and copper).
