Abstract:
1. A process of manufacturing a coated body comprising a substrate and a hard coating disposed on said substrate, wherein said 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 said surface, said process comprising: a surface smoothing step of smoothing a surface of said 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 said recesses each having the size of 0.5–6.0 μm are formed in said surface of said hard coating, wherein each of said abrasive particles used in said 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 said spherical-shaped core body.
