Effect of gas phase composition on functional-gradient coatings formation by supersonic cold gas dynamic spraying
https://doi.org/10.22349/1994-6716-2018-93-1-65-69
Abstract
The paper develops method for manufacturing wear and corrosion-resistant gradient coating. A special feature of the proposed method is the creation of chemical composition gradient due to controlled variation of the gas phase composition when applying supersonic cold gas-dynamic spraying. This ensures high adhesive strength of the composite coatings of the metal-non-metal system in combination with high micro-hardness of the peripheral layers. Such functional gradient coatings have wide practical applications.
