摘要： Disclosed herein are methods for coating metal substrates, systems therefore, and articles made therefrom. In one embodiment, the method of coating a metal substrate comprises: disposing a metallic bond coating on the metal substrate, creating ions with a reverse polarity high frequency apparatus at a frequency of greater than or equal to about 2.5 kHz, roughening the surface with the ions to a subsequent average surface roughness of greater than or equal to about 5 μm, and disposing a ceramic coating on the metallic bond coating surface. The metallic bond coating had a surface with an initial average surface roughness of less than or equal to about 1 μm.

摘要： A welding method and apparatus for welding workpieces together by conducting a laser beam welding process on a joint region that includes a weld seam defined by and between faying surfaces of the workpieces, and then conducting a hybrid laser arc welding process on the joint region. The laser beam welding process entails causing a first laser beam to travel along the joint region, penetrate the weld seam and form a weldment. The hybrid laser arc welding process remelts the weldment by simultaneously causing an electric arc and a second laser beam to overlap and travel along the joint region and form a weld pool in the weldment. On cooling, a weld joint is formed within the joint region and its weld seam.

摘要： A method of welding alloys having a ductility drop temperature range to limit strain-age cracking. The method involves the use of a welding device to weld a weld area of an article while maintaining temperatures throughout the weld area and a heat affected zone adjacent the weld area within a non-crack sensitive temperature range that is above a ductility drop temperature range of the alloy being welded. During welding, the temperatures of the weld area and the heat affected zone are predominantly controlled with heat input from the welding device. Once the welding has been terminated, the weld area and the heat affected zone are cooled from the non-crack sensitive temperature range through the ductility drop temperature range to a temperature below the ductility drop temperature range of the alloy.

摘要： A modified electron beam welding process effects welding of joints between superalloy materials by inserting a weldable shim in the joint and heating the superalloy materials with an electron beam. The process insures a full penetration of joints with a consistent percentage of filler material and thereby improves fatigue life of the joint by three to four times as compared with the prior art. The process also allows variable shim thickness and joint fit-up gaps to provide increased flexibility for manufacturing when joining complex airfoil structures and the like.

摘要： A fatigue load resistant structure includes a fatigue loaded portion and a weldable fatigue loading resistant feature. The fatigue loaded portion includes a first elongation material. The weldable fatigue loading resistant feature includes a second elongation material secured to the fatigue loaded portion of the fatigue loaded structure. The first elongation material is less ductile than the second elongation material, and the weldable fatigue loading resistant feature can reduce, retard, or eliminate formation of cracks due to tensile and compressive forces.

摘要： A welding method and an assembly for performing the method. Articles to be welded are placed together so that faying surfaces thereof face each other, a joint region is defined by the faying surfaces and juxtaposed surfaces of the articles, a shim is between and contacts the faying surfaces, and an edge portion of the shim protrudes from the juxtaposed surfaces. The articles are welded together by projecting onto the joint region a high-powered laser beam that is focused on the juxtaposed surfaces and intentionally unfocused on the edge portion of the shim so that portions of the laser beam are diffracted by the edge portion onto the juxtaposed surfaces. The laser beam and its diffracted portions melt the shim and the faying and juxtaposed surfaces of the articles. Cooling of the articles yields a welded assembly having a weld joint entirely through a through-thickness of the welded assembly.
