摘要： A rail repair method and insert therefor enables repair of rails and rail-like structures. A rail defect is initially identified and removed as contained within a volumetric material portion so as to form a contoured void while maintaining continuity of the rail opposite the void. A pre-formed insert is then placed into the void thereby effecting a rail-to-insert interface. Current is driven through the interface as force directs the insert against the rail. Resistance heat and pressure weld the insert to the rail. The flash welding aspects remove oxides and other impurities from the interface, and the forge welding aspects create a robust solid state weld. Excess material, whether flash, rail, or insert-based, is removed during the finishing processes to provide a virtually seamless rail repair. The solid state weld repair insert and underlying methodology enabled thereby may be used to repair any number of targeted metallic rail-like structures.

摘要： A method of preparing a particulate material comprising the steps of adding silicic acid solution, optionally doped with aluminum, optionally added to a slurry of pre-existing nanoparticles at a neutral to slightly acidic pH of no more than seven, and at a temperature of about 20° to 30° C. This yields a polysilicate particulate dispersion. Then, the pH of the dispersion is raised to greater than seven, to stabilize/reinforce particles of the particulate dispersion. Optionally, the particles may be dried, and have increased porosity and surface area.

摘要： A method for repairing defects in a metallic substrate including the steps of placing a consumable filler slug in contact with the substrate in the vicinity of the defect; bringing a first electrode and a second electrode in contact with the consumable slug and applying a pressure to the consumable slug; and transmitting electrical current between the electrodes for a period, thereby resistively heating the consumable slug and the metallic substrate resulting in coalescence in a substantially liquid pool that fills the defect. The pool is then cooled to solidification under the pressure of the electrodes. The electrodes are then removed from contact with the consumable slug and excess material may be removed. The consumable slug may be formed as a single unit or multiple sections, and may incorporate sacrificial retainers to add additional defect filling material, retain the pool, and seal the pool from atmosphere.
