Quality assurance with optical 3D measurement: the tribo test

In order to have sound knowledge about the longevity of a workpiece, one must know its tribological values. The tribo test tests a material pair for wear. The resulting surface changes, which reach into the nanoscale, provide valuable information about the nature, functionality and longevity of the workpiece.

The wear test is carried out to check the service life of highly stressed materials such as ball bearings, piston rings or gear parts. Signs of wear, for example, show in the properties of texture or deformation of the surface. The analysis of the interaction of the material pairings is therefore essential for a later low-friction process.

Check with the tribo test

The areal data acquisition determines the maximum depth, the removed volume and the displacement of material. When determining the relevant characteristics such as roughness, the tribological properties or the surface quality, the high-resolution 3D analysis of the surface plays a central role. The results expose any product defects and determine whether a workpiece is ready for its intended use.

Capture 3D structural features: MarSurf CM explorer

That's why accurate, reliable records are indispensable. With the MarSurf CM explorer, all tribologically relevant 3D structural features are recorded, with which comprehensive analyses and evaluations are possible. Compared to scanning electron microscopy (SEM), the MarSurf explorer also provides absolute 3D measurement values.
