Abstract: Disclosed is a method for the preparation of a sintered body of a high-chromium cast iron of a specified chemical composition having greatly improved mechanical, abrasion-resistant and corrosion-resistant properties as compared with conventional cast bodies of the same cast iron. The inventive method comprises the steps of preparing a powder of the cast iron alloy by quenching solidification of a melt, e.g., by centrifugal spray atomization, and sintering the powder under compression by the discharge plasma sintering method.
