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.
Claims17
A method of increasing the dynamic pressure resistance of a metallic component with a tubular internal space, in which a hard metal ball is forced under high pressure in the range of between 2000 and 7000 bars through the interior of the tubular internal space, wherein the hard metal ball is of a diameter larger than the inside diameter of the tubular internal space before the hard metal ball is forced therethrough.
