如何计算Corrosion Rate
learn.whatIsHeading
Corrosion rate quantifies material degradation: measured in mm/year or mils/year; depends on environment and material.
分步指南
- 1Input material, environment, exposure time
- 2Calculate mass loss or penetration depth
- 3Estimate service life
例题解析
输入
Mild steel in seawater: ~0.3-0.5 mm/year
结果
After 10 years: 3-5 mm penetration
Significant engineering concern
常见错误注意事项
- ✕Assuming uniform corrosion (pitting can be 10× faster)
- ✕Neglecting galvanic corrosion between dissimilar metals
常见问题
How do alloys reduce corrosion?
Chromium forms passive oxide layer; stainless steel >12% Cr dramatically reduces corrosion.
