Abstract:
The invention relates to a method of increasing the dynamic pressure resistance of a metal component with a tubular inner space, in which a hard metal ball is forced under high pressure through the interior of the tubular inner space, wherein the hard metal ball has a diameter that is greater than the inside diameter of the tubular inner space before the hard metal ball is forced through.
