FIELD: metallurgy. ^ SUBSTANCE: invention refers to powder metallurgy and can be used in chemical industry, aircraft engineering and power engineering. In order to obtain powder of disperse-strengthened ferritic steel, which has improved strength, molten steel totally containing 25-40 wt % of chrome and aluminium is sprayed. Prior to spraying yttrium is added to molten metal based on ratio between content of oxygen in sprayed powder, which is pre-determined on experimental heat, to yttrium content in molten steel which is equal to 0.2-0.35. ^ EFFECT: method for obtaining powder of disperse-strengthened ferritic steel is described. ^ 2 cl, 2 ex |
