The magnetron spraying method is used to obtain nano- and microscale surface layers of tantalum deposited on wire and on flat NiTi substrates. The structure and composition of layers are determined using scanning electron microscopy and Auger spectroscopy. With increase in the spraying time, the thickness of the surface layer grows nonlinearly, which leads to a change in X-ray contrast of the material relative to the substrate. On the basis of calculations of the linear attenuation coefficient for X-ray radiation, it is demonstrated that layered composites in the form of a plate having a surface layer on one side can be conditionally represented as a multicomponent monolith. When the sample is rounded, the continuous surface layer surrounding it from all sides has a greater effect on X-ray contrast. [ABSTRACT FROM AUTHOR] |
