Abstract
Method and device for coating cavities of objects such as the internal surface of tubes with the cathode arc deposition method. This method is used such that material from the cathode surface migrates and is deposited on the surface of said cavity. To this end the cathode is introduced into the cavity. The device for performing the above method comprises at least a cathode arc deposition device. The object to be coated can be connected as anode although it is also possible that a separate anode is provided in which case a voltage is applied to the object being negative with regard to the voltage applied to the cathode.
