Opis:: The resultes of anodic oxide conversion coatings on wrought AZ61 magnesium alloy production are describe. The studies were conducted in a solution containing: KOH (80 g/l) and KF (300 g/l) using anodic current densities of 3, 5 and 10 A/dm² and different process durations. The obtained coatings were examined under a microscope and corrosion tests were performed by electrochemical method. Based on these results, it was found that the low-voltage process produces coatings conferring improved corrosion resistance to the tested magnesium alloy.

Opis:: In the paper we experimentally and theoretically analyze diffraction of light propagating through a microstructured optical fiber on the fiber end face. In the measurements the diffracting light is spatially inhomogeneous and the diffracting object is a solid-state core with a triangular shape. Application of optical system enables detailed experimental investigations of evolution diffraction pattern in the near-field region, in particular, rotation of the observed structure while departing from the fiber end. The experimental results are confirmed with theoretical simulations based on the theory of the Fresnel diffraction.
