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.
