Abstract: A method of seamless bonding comprises in sequence: feeding a filler wire into a de-scaling unit; removing with the de-scaling unit a contamination layer disposed onto a core of the filler wire, removing the contamination layer comprising: applying a laser beam to the filler wire at a wavelength causing at least a portion of the contamination layer to break away from the core of the filler wire while leaving the core unaffected; and feeding the filler wire to a seamless bonding unit. A seamless bonding device is also presented.

Abstract: A method for repairing a cast component made of a magnesium-based material is disclosed. The method comprises receiving the cast component made of the magnesium-based material and adding repair material to the cast component using cold metal transfer (CMT) welding.

Abstract: A method of spray coating a surface having a magnesium base is provided. The method includes, in sequence, applying a magnesium oxidizing agent onto the surface; determining whether an entirety of the surface has oxidized as a result of applying the magnesium oxidizing agent onto the surface; and spray coating the surface.

Abstract: A method for applying a coating to a substrate surface is provided. The method involves cold spraying a coating material against the surface of the substrate at a first velocity. The first velocity is lower in magnitude than a critical velocity. The method also involves cold spraying the coating material against the surface of the substrate at a second velocity. The second velocity is greater in magnitude than the critical velocity. The critical velocity is a threshold velocity below which the coating material is substantially deflected by the surface of the substrate and above which the coating material substantially adheres to the surface of the substrate.

Abstract: A method of cold spray coating a target surface of a component, the coating provided using selected solid powders, the method comprising: placing a mask onto the component to cover an area of the component adjacent the target surface which is not to be coated, the mask having a masking top surface provided of a material selected to be non-adhesive with the selected solid powders when cold-sprayed onto the masking top surface, the mask having a melting point above a temperature at which cold spray is performed; cold spraying the target surface with the selected solid powders, including at least some overspraying onto the mask; removing the overspray from the mask; and removing the mask from the component. A mask for a cold sprayed component of a gas turbine engine is also presented.

Abstract: A method of coating an aluminum alloy or magnesium alloy component, including cleaning and drying surfaces of the component to be coated; suspending a powdered coating material in a carrier gas and feeding the suspended powdered coating material through a plasma torch in a flowing gas; heating the coating material in the plasma torch to a molten or semi-molten state using a nominal power below 25 kW; and depositing the coating material with the plasma torch directly on the surfaces to be coated. The component may be made of a magnesium alloy containing at one or more of zinc, cerium and zirconium, or of an aluminum alloy containing one or more of magnesium, silicon, copper and chromium. The powder material may be made in majority of aluminum.

Abstract: The present invention relates to an anchor for floating devices and includes a body provided with a shackle linked to an anchor chain, with one set member for engaging the bed of a body of water being jointedly mounted on said body. The body includes a first portion having two longitudinal ends and a second portion extending between the ends of the first portion and being spaced away so as to surround a void space therebetween. The shackle is slidingly mounted along the second portion and the set member is assembled on the first body portion in a jointed fashion to thereby be able to switch between set positions pointing oppositely from each other.

Abstract: Process for the preparation of filled heat-curable compounds of the polyurethane type by reaction of condensation of the constituents of the desired compound in the presence of a pulverulent filler, which is characterized in that the said filler is predispersed in the presence of a stabilizing agent in a liquid organic phase compatible with the desired heat-curable compound in the course of its formation reaction, the said filler being then in the form of a homogeneous and stable suspension, and the suspension thus prepared is then introduced into the reaction mixture before, during or after the introduction of at least one of the constituents of the desired heat-curable compound.The process according to the invention makes it possible to produce compounds of the polyurethane type whose mechanical and physical characteristics are at least equivalent or even improved in relation to those of the unfilled identical compounds by virtue of the excellent distribution of the inorganic filler.
