Electric arc spraying

Electric-arc-sprayingArc-spraying is characterized by its economy. High spray rates with relatively low energy consumption allow cost-saving repair coating in the event of damage from abrasion.

Two metallic wires are fed together by electrically-conducting wire guides at a regulated feeding speed. The spray material is completely melted by the short-circuit current. Using an atomizing gas, the melted material is converted into fine particles and shot onto the pretreated workpiece. Depending on the spray material, the particles reach speeds of up to 150 m/s. Another advantage is the low warming of the base material that is to be coated. Coating thicknesses of multiple millimeters can be reached. In addition to carbon-steels and high chrome steel alloys, filler wires with hard materials can be applied as well. Moreover, pseudo-alloys can be produced in this way by using two different wire materials. Depending on the composition, these can open up completely new possibilities for solving corrosion and abrasion problems. The superior properties of the two spray materials are unified.
