Table 3
The modified Goldberg score [
9] according to Cusick et al. [
11].
| Damage | Score | Criteria |
| Minimal | 1 | Fretting on <10% of the surface and no corrosion damage | Mild | 2 | Fretting on >10% of the surface and/or corrosion attack confined to one or small areas | Moderate | 3 | Fretting on >30% of the surface and/or aggressive local corrosion attack with corrosion debris | Severe | 4 | Damage over the majority (>50%) of the surface with severe corrosion attack and abundant corrosion debris |
