AI Technical Summary
Traditional Vickers hardness testing stages are susceptible to contamination from dust, oil, or moisture, which can cause small nanocrystalline alloy samples to be placed at an angle or experience uneven stress, resulting in blurred indentation edges and consequently affecting the accuracy of hardness calculations.
A Vickers hardness testing device for nanocrystalline alloys was designed. A servo motor drives a gear meshing ring to rotate a rotating disk, which in turn causes a protective cover to open or close, forming a closed protective space to block contaminants and ensure the cleanliness of the testing platform.
It achieves automated and rapid protection of the testing station when not in operation, avoiding frequent manual operation, improving the convenience of the testing process and the reliability of protection, and ensuring the accuracy of hardness calculation.
