Název v původním jazyce

Stress Gradients in Plasma Sprayed Chromia Coatings

Popis výsledku v původním jazyce

It is generally known that plasma sprayed coatings exhibit rather a low strength thanks to their characteristic microstructure with porosity and microcracks. To determine the role of varying types of deformation in different parts of the coatings profile, 1.8 mm thick Chromia coatings on a steel substrate were made using WSPŽ plasma spray. Stress gradients were then measured "in-situ" on a four-point bending device during bend deformation of the coated beam using neutron diffraction. Only compressive loading in coatings increased the resulting stresses. From the plot of stresses vs. applied strain (linear dependence) the Young's moduli of the substrate and the coating were determined. Both values agree well with those obtained by mechanical testing.
