Coverage Analysis
Peening Coverage Calculator
Calculate peening coverage, determine optimal exposure times, and verify 100% surface treatment per SAE J443 requirements.
Coverage Calculation
Typical rates: 20-40%/min for air blast, 30-60%/min for wheel systems
Coverage Requirements by Application
| Application | Min Coverage | Verification Method |
|---|---|---|
| General automotive | 100% | Visual inspection |
| Aerospace structural | 200% | Fluorescent tracer |
| Critical aerospace | 500% | Almen strip + visual |
| Medical devices | 1000% | Microscopic examination |
Coverage Verification
- 1.Apply fluorescent tracer dye to component surface
- 2.Peen under UV light to observe coverage progression
- 3.100% coverage = complete removal of dye from surface
- 4.Document coverage with photographs under UV light
