Leeb hardness test

The Leeb hardness test is a method used to measure the hardness of metals and materials. It involves using a small device that fires a ball or a small mass at the material's surface. The device then measures how much the projectile bounces back. This rebound velocity helps determine the hardness of the material: harder materials will generally cause the projectile to bounce back more. It’s a handy, portable test often used in industrial settings because it allows for quick and accurate assessments without needing to damage the material being tested.
