Abstract
Disclosed is a method of making a seal comprising fabricating a seal body that includes a first friction surface including nickel and cobalt. The first friction surface on the seal body is contacted with a metal counter-body surface including nickel. Pressure and heat is applied between the seal body and the counter-body, and motion is applied between the seal body and the counter-body with respect to each other in a direction parallel to the first friction surface, followed by separating the seal from the counter-body.
