Table 1.
Mean (standard deviation) of repassivation times (Tre; ms) from the last scratching cycle for both commercially pure titanium (CP-Ti) and titanium alloys containing 20 mass% chromium (Ti-20Cr) at different scratching speeds.
| Specimens | Scratching Speed | ||
|---|---|---|---|
| 10 mm/s | 20 mm/s | 40 mm/s | |
| Commercially pure titanium (CP-Ti) | 312 (31) a,A | 152 (23) b,A | 108 (26) b,A |
| Titanium alloys containing 20 mass% chromium (Ti-20Cr) | 378 (19) a,B | 173 (33) b,A | 80 (13) c,A |
Results of statistical analysis are represented by lower and upper case letters. Different lowercase letters in the same column indicate that the groups are significantly different (p < 0.05). Different upper case letters in the same row indicate that the groups are significantly different (p < 0.05).
