Frictional coating for use in e.g. turbine, has coating material and several frictional lines made of coating material, where lines are arranged distributed in circumferential direction

摘要

The coating has a coating material effecting abrasive in frictional contact with a stator part. The coating is formed of several frictional lines (10) made of the coating material and arranged distributed in the circumferential direction. The lines run linearly and orient perpendicular to the rotation axis of the rotor. The lines are identical and are arranged uniformly distributed in the circumferential direction.
