Nanostructured Multilayer Coatings for Spatial Filtering [PDF]

Advanced Optical Materials, 2021
AbstractSpatial filtering is an important mechanism to improve the spatial quality of laser beams. Typically, a confocal arrangement of lenses with a diaphragm in the focal plane is used for intracavity spatial filtering. Such conventional filtering requires access to the far‐field domain.

Microstructure and mechanical properties of thermal sprayed nanostructured Cr3C2-Ni20Cr coatings

Materials Research, 2008
Cr3C2-Ni20Cr coatings have been used for corrosion and wear resistant applications. However, one of the shortcomings of these coatings is its low hardness, and consequent low wear resistance, for long term high temperature applications.
