ABSTRACT:
A process of manufacturing a coated body including a substrate and a hard coating disposed on the substrate, wherein the hard coating has (a) a surface smoothed to have a roughness with maximum height Rz of not larger than 1.2 μm, and (b) recesses each of which has a size of 0.5–6.0 μm and is formed in the surface, the process including a surface smoothing step of smoothing a surface of the hard coating by using abrasive particles such that the smoothed surface has the roughness with the maximum height Rz of not larger than 1.2 μm and such that the recesses each having the size of 0.5–6.0 μm are formed in the surface of the hard coating, wherein each of the abrasive particles used in the surface smoothing step is provided by a spherical-shaped core body made of a rubber and having a particle size of 0.1–2.0 mm, and hard abrasive grains each having a size of #3000–#10000 and adhering to an outer surface of the spherical-shaped core body.
