Abstract

PURPOSE:To carry out the efficient and uniform nitriding treatment in a short period of time, by interposing the draft layer between the inner wall of the vessel and the powdery material of steel and by introducing the gas for treatment through this layer, at the nitriding treatment of the powdery material of steel.
