ADMET recently designed a customized shear fixture for shearing thermal spray coatings off of a substrate. The fixture particularly focuses on shearing a very small coating area.
The substrate is clamped inside of the shear fixture from the back side, and a replaceable carbide shear insert is mounted on the front side. The insert holder is mounted on a digital micrometer head to achieve precise shear insert positioning down to 0.0005″ off of the substrate.
A convenient viewport on the front of the fixture allows for easy integration of a USB microscope to record and measure failure modes/fractures.
This customized shear fixture is engineered-to-order and can be designed to accommodate your unique shear testing requirements. Contact us to learn more.
