Abstract
A seal intended to wear from abrasion for use in contact with a rotor zone of a rotating machine, of the type made up of a dispersion of hollow microspheres in a binder providing cohesion of the microspheres among themselves and their attachment to a metallic support. In order to make it possible to produce the seal by torch spraying from a powdered mixture onto the support, the hollow microspheres are made of an inorganic refractory material and the binder material is a metallic material more fusible than the material of the microspheres.
