Abstract
An abrasive particle, for use in a manufacturing method in which the particle is exposed to a high energy beam, such as a laser, is provided with an abrasive core having an enclosing coating which protects the core from detrimental deterioration during exposure to the beam. In one form, the coating is multilayer. The particle is included on a surface of a member of a rotary seal for abrading an opposing surface.
