ABSTRACT:
A method of formation of a coating film on the surface of a cylindrical base material such as a piston wherein a waste of the lubricant coating solution is prevented and a lubrication action is maintained. A cylindrical base material is rotably supported horizontally on a rotating support device and in rotation, a coating solution is supplied to a coating surface, and a coating film is coated on the surface of the cylindrical base material. A coating former equipped with a blade is inclined at an angle of 20° to 80° with respect to a tangential direction of rotation, the blade is separated from the coating surface by exactly a coating layer thickness, and further the cylindrical base material is rotated by ¼ of a turn or more.
