Table 5.
Surface roughness of SSP and ELP plates with and without type A and B deposits.
| Surface | Ra (nm) | Rms (nm) | Thickness (nm) |
|---|---|---|---|
| SSP | 30.70 ± 0.06 c | 41.30 ± 0.01 c | ND |
| Type A | 63.10 ± 0.08 a | 84.60 ± 0.02 a | 100.50 ± 0.01 a |
| Type B | 42.20 ± 0.20 b | 56.10 ± 0.6 b | 80.50 ± 0.03 b |
| ELP | 0.11 ± 0.01 c | 0.15 ± 0.02 c | ND |
| Type A | 13.15 ± 0.15 a | 16.83 ± 0.13 a | 14.83 ± 2.17 a |
| Type B | 4.03 ± 0.13 b | 5.26 ± 0.21 b | 8.66 ± 1.64 b |
Ra: arithmetic mean roughness. Rms: quadratic mean roughness. Different letters (a–c) in the same column for each plate indicate significant difference (p < 0.05).
