Název v původním jazyce

Protective over-layer coating preventing cracking of thin films deposited on flexible substrates

Popis výsledku v původním jazyce

The article reports on a special over-layer which protects brittle coatings deposited on flexible substrates against cracking during bending. It is shown that the over-layer with (i) the low effective Young's modulus resulting in a high ratio H/E higherthen value 0.1, (ii) the high elastic recovery We higher then 60% and (iii) the compressive macrostress deposited on a brittle coating can prevent its cracking during bending. The possibility of how to prevent cracking of the brittle coatings is demonstrated experimentally. Besides, the mechanical behavior of the coatings composed of three and four layers is described in detail. Obtained results can be used in the development of flexible coatings, strengthening of the surface of brittle materials.
