Microflake

Microflakes are extremely small particles or very tiny flakes that detach from metal surfaces or other materials, often looking like miniature scales. In aviation, microflakes can form due to wear, fatigue, or corrosion of aircraft components. Their presence may indicate early signs of material degradation, structural weakness, or contamination. Detecting microflakes is important for maintenance and safety checks, as they can be an early warning of damage or failure in parts.
