<p>The present invention relates to a method for the thermal treatment of metal objects, particularly sintered permanent magnets containing rare earth metals, in which method the permanent magnets are coated by means of the gas phase coating method in connection with the thermal treatment. The permanent magnets are advantageously of the form RE2T14B, where RE is a rare earth metal, T is a transition metal and B is borium, and the employed method for coating the permanent magnets is advantageously the ion coating method.</p> |
