Patent attributes
Flaky particles whose thickness is ½ or less of a long side of a flat surface thereof are continuously injected together with a compressed gas onto a layer-forming surface of a workpiece to orient the flaky particles so that its flat surface is in line with the surface of the workpiece. By coating a binder to the surface of the workpiece in advance, a bonding between the flake particle thus oriented and the workpiece may be accomplished via this binder, or by generating heat at a point of collision between the surface of the workpiece and the flaky particle and at a collision point in which the subsequent flaky particles collide with the flaky particles that have already reached the surface of the workpiece, the bonding may be accomplished by means of this heat.
