Abstract
An atmospheric pressure plasma source includes a body including a distal end, a blade extending from the distal end and terminating at a blade edge, a plasma-generating unit, and a plasma outlet communicating with the plasma-generating unit and positioned at the distal end. The plasma outlet is oriented at a downward angle generally toward the blade edge, wherein the plasma outlet provides a plasma path directed generally toward the blade edge. The plasma may be applied to the coating at an interface between the coating and an underlying substrate. While applying the plasma, the blade is moved into contact with the coating at the interface, wherein the blade assists in separating the coating from the substrate while one or more components of the coating react with energetic species of the plasma.
