| Abstract Scope |
Accurate measurement of projected contact areas is crucial for determining material hardness. Traditional nanoindentation methods, which measure indent depth to calculate the projected area, often overestimate hardness due to unaccounted material pileup. Our research automates the measurement of projected contact areas using an optical profilometer, which accurately assesses both the area beneath the surface plane and the pileup material. Manual measurements of indents are laborious and prone to error. Automated image acquisition and contact area measurement ensure precision and repeatability. This approach addresses the limitations of manual methods and traditional nanoindentation, enhancing the efficiency and accuracy of hardness measurements. Our efforts aim to enable high-throughput materials development, facilitating rapid and reliable characterization of material properties in industrial and research applications. |
