Abstract The possibility of applying the friction surfacing process for production functional gradient layered compositions tribotechnical purposes has been considered. influence technological parameters process: rod rotation frequency, longitudinal linear speed movement and method substrate surface preparation on deposited layer formation shown.

Iron aluminides are considered as candidate materials for high temperature applications their excellent corrosion and oxidation resistance. In the present work, iron-aluminide coatings were developed by friction surfacing (6351 aluminum alloy deposited on a low-carbon steel substrate) followed diffusion heat treatment. The initial found to be geometrically homogenous adhered well substrate. tre...
