In a method is provided for removing a material from a substrate, a plasma is generated at atmospheric pressure. The plasma includes an energetic species reactive with one or more components of the material. The plasma is flowed from an outlet as a plasma plume that includes periodic regions of high plasma density and low plasma density. The material is exposed to the plasma plume. At least one component of the material reacts with the energetic species, and at least one other component of the material is physically impacted and moved by one or more of the regions of high plasma density.

Plasma source and method for removing materials from substrates utilizing pressure waves

A ballast transformer and system using the ballast transformer to couple power to a plasma load. The ballast transformer has a magnetic core, a first primary winding on a primary side of the magnetic core, a secondary winding on a secondary side of the magnetic core, and a second primary winding connected in series with the first primary winding and wound in proximity to the secondary winding on the secondary side of the magnetic core. The first primary winding is connectable to the AC power source, and the secondary winding is connectable to the plasma load via a coaxial cable.

Asymmetrical ballast transformer

An adhesion promoting layer is formed on a metallic substrate by generating a non-thermal plasma in air at atmospheric pressure, and exposing a surface of the metallic substrate to the plasma. The plasma oxidizes the metallic substrate to form metal oxide from metal atoms of the metallic substrate. The metal oxide is formed as a metal oxide layer disposed directly on an underlying bulk metallic layer of the metallic substrate. Alternatively, the plasma nitridizes the metallic substrate to form metal nitride from metal atoms of the metallic substrate. The metal nitride is formed as a metal nitride layer disposed directly on an underlying bulk metallic layer of the metallic substrate.

Method and device for promoting adhesion of metallic surfaces

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.
