Home Services Material Recycling and Reclamation Aluminum Twin Wire Arc Spray Coating ALUMINUM TWIN ARC SPRAY COATING YIELDS HIGHEST PRECIOUS METAL RETURNS Materion’s precision parts cleaning service offers our customers a one-stop solution for thin film deposition materials. In addition to precious metal recovery and refining services, we offer in-house aluminum twin arc spray coating services. This surface treatment increases the lifetime of shields and maximizes tool up time - thus lowering the total cost of ownership. HOW ALUMINUM TWIN ARC SPRAY COATING WORKS Twin arc spray is particularly beneficial to Materion customers who use PVD process tools for producing coatings in the semiconductor industries. It differs from other thermal spray processes in that there are no external heat sources. Rather, heating and melting occur when two electrically opposed charged metal wires, comprising the spray material, are fed together in such a manner that a controlled arc occurs at intersection. This molten metal is atomized and propelled onto the prepared shield substrate by jets of compressed air or gas. Materion uses an automated system utilizing a robotic arm for proper positioning to meet stringent customer specifications for coating thickness and surface roughness uniformity.
