| Popis: | In present paper, the NiAl intermetallic was used as a matrix for elaboration of new composite coatings with hard additives like CrB 2 and ZrB 2 borides. The composite materials of NiAl-CrB 2 and NiAl-ZrB 2 systems were obtained by sintering of initial powders in vacuum. The composite powders were deposited by atmospheric plasma spray (APS) and detonation (D-gun) methods. Investigation of phase composition of developed composite materials as well as coatings obtained from them, the XRD analyses were performed. The microstructure of composite coatings has been investigated using SEM and TEM methods. |
