When solid materials are used in a state where they rub against each other, one (or both) wears out and the wall thickness decreases, a phenomenon called wear.
Countermeasures
After a certain period of use, it is necessary to perform the following inspections and evaluations to prevent fracture:
- Subcategory: Wear
- Damage mode: Metal loss (Thinning)
- Inspection: Visual inspection, measurement of metal thickness.
- Evaluation: Prediction of metal thinning rate, assessment of remaining service life.
- Actions: Establish criteria for metal buildup repair, component replacement, and material change based on the assessment.
