Покрытия были получены с помощью магнетронного распыления мозаичных мишеней, содержащих сегменты Mo−xLa2O3 (х = 5, 20, 40%). Показано, что наиболее эффективным с точки зрения повышения твердости, упругого восстановления, индекса пластичности, сопротивления упругой деформации и жаростойкости покрытий является введение в их состав 3 ат. % La.</p></abstract><trans-abstract xml:lang="en"><p>Comprehensive studies of nanocomposite coatings in the Mo–Hf–La–Si–B system with different lanthanum content have been carried out.
