Patent number: 7707895Abstract: The invention relates to a method for examining the resistance of a connection between two bodies, whereby one of the bodies only has a small mass. A correspondingly directed force is exerted upon the connection until disconnection thereof. The force used is the centrifugal force which acts at a distance from a rotational axis in a concentric manner about said rotated connection. Said method is particularly advantageous if the body having a small mass is a coating which is applied to the other body. In order to obtain a sufficiently high centrifugal force, an examining stamp is applied to the body having the small mass and/or the coating on the side oriented away from the connection. The adhesion between the body and/or the coating and the examining stamp is greater than between both of the bodies and/or the coating and the other body.Type: GrantFiled: November 11, 2005Date of Patent: May 4, 2010Assignee: BAM Bundesanstalt fur Material-Forschung und-PrufungInventors: Uwe Beck, Georg Reiners, Christian Berndt, Sylke Grune, Rüdiger Uhlendorf
