POWDER OF IRON-BASED ALLOY FOR WEAR-RESISTANT SURFACING AND SPUTTERING Russian patent published in 2017 - IPC C22C38/36 B22F3/105 B23K35/30 

FIELD: chemistry.

SUBSTANCE: invention relates to powder alloy, which can be used for application of wear-resistant and corrosion-resistant coating by deposition or sputtering. Powder of iron-based alloy contains 2.9–3.3 wt% carbon, 0.4–1.0 wt% silicon, 0.4–1.2 wt% manganese, 17–21 wt% chromium, 0.15–1.2 wt% aluminium, 3–4.5 wt% vanadium, 0.02–0.12 wt% barium, not more than 0.06 wt% sulphur and not more than 0.07 wt% phosphorus.

EFFECT: higher impact-abrasive wear resistance, as well as stabilisation of hardness of surfaced coat.
