An apparatus is disclosed for coating a surface that is movable relative to the apparatus with a layer of metallic particles or particles having a metal-like appearance and reflectivity, the particles adhering more strongly to the surface than to one another. The apparatus comprises at least one spray head for directly or indirectly applying to the surface a fluid stream within which the particles are suspended, a housing surrounding the spray head(s) and defining an interior plenum for confining the fluid stream, the housing having a rim adjacent the surface that is configured to prevent egress of particles from a sealing gap defined between the rim of the housing and the surface to be coated, and a suction source connected to the housing to extract from the plenum the sprayed fluid and particles suspended in the sprayed fluid. In operation, the suction source extracts substantially all particles that are not in direct contact with the surface, so as to leave only a substantially single particle layer adhering to the surface on exiting the apparatus.

Disclosed are a skin-attachable adhesive patch mimicking a leg structure of a diving beetle and having excellent skin-attachment ability even in a dry or wet condition, and a method for manufacturing the same. The skin-attachable adhesive patch includes a substrate; a plurality of negative pressure chambers formed on a surface of the substrate, wherein each of the plurality of negative pressure chambers has a truncated hollow sphere structure; a micro-wrinkle layer formed on at least a portion of a remaining area of the substrate except for an area thereof where the negative pressure chambers are formed; and a patterned carbon particle layer formed on the micro-wrinkle layer.

Methods and systems for coating metal substrates are provided. The methods and systems include sequential application of low flow and high flow powder coatings followed by a single heating step to provide a cured coating. The methods and systems include a marker that allows coating uniformity to be monitored and assessed during application. The described methods provide coatings with optimal surface smoothness and edge coverage.

A method to prevent corrosion of a susceptible article of a two-article system, in which first and second articles of the two-article system have surfaces facing one another and in which the two articles have different anodic indices includes applying a coating material to the surface of the first article and curing the coating material on the surface of the first article. The method further includes contacting and securing the surface of the first article with the surface of the second article. The two articles exhibit substantially no corrosion following exposure to a corrosive environment under standard GMW17026 for a 15 year simulated test.
