Fig. 2 Analysis of surface defects of
Si3N4 ceramic bearings roller inner ring
The pixel 3D map of Si3N4 ceramic
bearing inner ring surface defect image is drawn by python programming
language, as shown in Figure 2. The distribution of surface defects is
observed through the pixel 3D map. Figure 2(e1-e4) represents the pixel
3D map of pit, wear, snowflake and crack defects respectively, and the
distribution locations of defects are marked in the map.
