This book is a collection of reports (reviewed) selected from several sections of the IEEE Nanomaterials: Application and Properties-2023 conference. The book is devoted to the study of films, coatings, and materials obtained by various methods of preparation and deposition, for example, magnetron sputtering of targets, vacuum arc deposition , electron-plasma processing, sintering of composites, plasma jet deposition, and other methods for obtaining nanomaterials. The chapters and reports describe superhard coatings, spark, and plasma alloying of materials (metals, semiconductors, polymers, ceramics).
