摘要： PROBLEM TO BE SOLVED: To provide a method of quantitatively measuring a coverage of iron-based powder, in which coverage of binder, auxiliary material, lubricant, or flow improving particle, affecting significantly properties and adhering on surface layer of the iron-based powder, is measured and the method is particularly preferable when carbon-containing material other than carbon black is used as the binder, auxiliary material, lubricant, or the like or carbon black is used as flow improving particles. SOLUTION: The method of measuring a coverage of iron-based powder includes irradiating the surface layer of the iron-based powder with electron beam, accelerated by an acceleration voltage selected from 0.1 to 5 kV; measuring an amount of secondary electron emitted from the surface layer of the iron-based powder; and deriving the coverage of carbon-containing material at the surface layer of the iron-based powder from the amount of secondary electron. Alternatively, the method of measuring a coverage of iron-based powder includes irradiating the surface layer of the iron-based powder with electron beam, accelerated by an acceleration voltage selected from 0.1 to 2 kV; and deriving similarly the coverage of carbon black in relation to carbon-containing material coating the surface layer of the iron-based powder.
