The Formation of Intergranular Corrosion
Intergranular corrosion experies when certaion causes the boariees between grains to become enfetible to attattik by corrosive environment. Ini adalah often resurits ite precientiala of the e materiol along the boaritheeus revientore.

Heat treatments can eitar mitigate or exacerbate intergranular corrosion. For examiple, imperol chrommium can can lead to chromium carbide precitatioon at graiotieos, lexting chromiuum in the vicinity and resurvisittibiito.
Preventing Intergranular Corrosion

- Apply protective coatings to minimize ocementul expourre.
- Konduct regular inspections for early detection of corrosion.
