<p>A coating solution that contains 10 to 20% by weight of epoxy resin serving as a thermosetting resin, 20 to 30% by weight of MoS 2 , and 5 to 10% by weight of graphite, with a remainder thereof constituted by an organic solvent, is sprayed onto a wrap portion side face 24a of an orbiting scroll 20 from a spray nozzle 52. While spraying the coating solution, the orbiting scroll 20 is rotated on a rotating table 32 and the spray nozzle 52 is moved along a rectilinear movement path L toward a radial direction outer side of the orbiting scroll 20 while maintaining an attitude thereof from the start of the spraying process. After applying the coating solution, the coating solution is dried by baking, whereupon a break-in operation is performed. As a result, an elastic coating 28 is formed at a coating thickness that enables elastic deformation in accordance with a clearance between the wrap portion side faces.</p> |
