Method for adjusting the electrical conductivity of a coating of a machine part, whose electrical conductivity can be modified by pressure, by radiation of dry ice.

摘要

Use of a particle beam (8) formed by dry ice particles for adjusting the electrical conductivity of a coating (4) of a machine part (1), especially a component of turbine, whose electrical conductivity can be modified by pressing, in which to adjust the electrical conductivity beam dry ice (8) is guided on the coating surface (4) and wherein the parameters of radiation during radiation are chosen such that not produce any abrasive erosion of the coating (4).
