A method of manufacturing a charge dissipative surface layer on a member made from or consisting of a dielectric polymeric material or polymer-based composite which is intended to be used in space and other extreme environments, the member having at least one surface, in particular two opposing surfaces, each of the surfaces having a flat or a three-dimensional shape. The method includes carbonizing the at least one surface of the member in a vacuum environment through ion bombardment with simultaneous surface renewal in a dynamic way, by bombardment of the at least one surface with an ion beam formed in a gaseous linear high-current technological ion beam source of rare gas and added predetermined amount of a carbonaceous gas in the same ion beam gas admixture in order to achieve a treated carbonized surface layer with a uniform surface resistivity in a charge-dissipative range.

Method for manufacturing a charge dissipative surface layer

A method of making a charge dissipative surface of a dielectric polymeric material with tunable (selectable) surface resistivity, comprises the step of controllably carbonizing the surface of the polymeric material in a vacuum environment by bombarding the polymeric surface with an ion beam of rare gas ions, the energy level of the ion source being from 2.5 to 30 keV, in the fluence range 1E16-5E17 ion/cmso as to reach a surface resistivity in the static dissipative range of 1E6 to 1E9 ohm/square at room temperature, with a temperature dependence of less than three orders of magnitude between &#x2212;150&#xb0; C. and +150&#xb0; C., while having no impact on the RF performance of the material, with high RF power handling capability, and with tunable thermo-optical properties of the surface, including negligible impact on the thermo-optical properties and RF performance of the material, if required by applications.

An ultrasound device for the treatment of surfaces and welded joints is disclosed. The device has a housing with a plurality of shaped slots formed therein. A reciprocally moveable sleeve is attached to the housing, and contains an ultrasonic transducer. A reciprocally moveable attachment is attached to an operating end of the sleeve, and has a detachable working head mounted thereon. A pin is positioned in a pin slot on the housing, and anchors the sleeve to the housing to limit movement of the sleeve. The pin is biased towards the front of the pin slot by means of a spring, and a moveable spigot provides a predetermined contact force between the ultrasound device and a work surface. The spigot has spigot pins that are inserted into the plurality of shaped slots in the housing in order to restrict axial movement of the spigot, thereby providing added compression or tension to the spring in order to provide the predetermined contact force.
