New Multifunctional FGM Coatings Produced Using ESA and TRESS Methods

摘要

The influence of nanodispersed complex additives (ZrO_2, Al_2O_3, W, WC, WC-Co, NbC, Si_3N_4) to SHS electrode materials on the mass transfer, structure and properties of electrospark coatings has been considered dependent on variation of the energy regimes of processing. The influence of the pulse discharge energy on the structure, composition, and properties of TRESS coatings has been studied. The optimum energy regimes of depositing high-quality multifunctional graded ESA and TRESS coatings have been found. It has been shown that introduction of nanodispersed complexes into electrode materials promotes improvement of the properties of ESA coatings.
