This dynamic hardness testing technique determines materials hardness primarily based on the power lack of an impression physique after colliding with a take a look at floor. An outlined impactor, propelled by a spring pressure, strikes the fabric, and the ratio of the rebound velocity to the impression velocity is measured. This ratio is then correlated to a hardness worth, usually displayed in Leeb Hardness Models (HL). The upper the rebound velocity, the more durable the fabric being examined.
This method provides the benefit of portability and ease of use, making it appropriate for on-site hardness measurements of huge or immovable objects. It’s also comparatively non-destructive in comparison with static indentation strategies. Its growth offered a precious different for assessing the hardness of supplies in conditions the place conventional laboratory testing is impractical, increasing the scope of high quality management and supplies analysis in varied industries.
