Abstract: A coating method comprises a workpiece acquiring step of acquiring a workpiece in which a metal member and a resin member the surface of which is activated by electron beam irradiation are connected to each other, and a coating step of applying a coating material to the metal member and the resin member of the workpiece.

Abstract: Provided is a coating device which can spray, while mixing uniformly, a plurality of kinds of base materials and a curing agent. The coating device comprises a supply pipe (12) for delivering the base materials and curing agent, and a rotary atomization head rotating about a line passing through the distal end face of the supply pipe (12) and atomizing and spraying the base materials and curing agent delivered from the supply pipe (12). The rotary atomization head comprises a spreading portion spreading toward the spraying direction while surrounding the distal end face of the supply pipe (12), and a substantially disc-shaped closing portion facing the distal end face of the supply pipe (12) and closing the inner wall surface of the spreading portion.

Abstract: An electrostatic coating method is provided. The electrostatic coating method includes: providing a rotary atomization type coating apparatus; supplying a coating material to a rotary atomization head of the rotary atomization type coating apparatus; changing the number of rotations of the rotary atomization head to change a particle diameter of particles of the coating material; adding a solvent to the coating material so that a NV value of a coated film formed on a coated surface of a workpiece falls within a predetermined range; and electrostatically coating the coated surface with the coating material.
