Aspects of the present disclosure provide titanium-based coatings and methods for making titanium-based coatings on surfaces. In at least one aspect, a coating includes an oxygen content, a fluorine content, a titanium content, and a sodium content. In one or more additional aspects, a coating includes titanium dioxide and NaTiF. In one or more additional aspects, a method of making a titanium-based coating includes contacting a substrate with a composition that includes from about 0.01 M to about 0.8 M of a titanium fluoride, from about 0.01 M to about 2 M of a sodium salt, and from about 0.1 M to about 1.5 M of a fluorine scavenger.

Titanium-based coatings and methods for making coatings

A crystalline titanium and magnesium compound having an X-ray diffraction pattern having interplanar spacing (d-spacing) values at about 5.94, 3.10, 2.97, 2.10, 1.98, 1.82, and 1.74±0.1 angstroms may be used in protective coatings for metal or metal alloy substrates. The coatings exhibit excellent corrosion resistances and provide corrosion protection equal to or better than typical non-chromate coatings.

A method of forming a monolithic aircraft structure having multiple aerodynamic surfaces includes forming a body component to have a body skin defining a body skin outer surface, and a body side wall integrally formed with the body skin and defining a body mating surface, the body skin outer surface providing a first aerodynamic surface. A cover component is formed to have a cover mating surface and a cover outer surface opposite the cover mating surface, the cover outer surface defining a second aerodynamic surface. The body component is positioned relative to the cover component so that the body mating surface engages the cover mating surface. At least portions of the cover mating surface are friction stir welded to the body mating surface to form friction stir welded joints between the body component and the cover component.

The present disclosure is directed to a method of making a composite part. The method comprises covering a mold tool for a composite part with a parting film. The method further comprises laying up at least one layer of pre-preg on the parting film covering the mold tool to form a laid-up composite part and removing the laid-up composite part from the parting film. The parting film comprises a polymer sheet having a first major surface and a second major surface; and a first adhesive disposed on the first major surface of the polymer sheet, the first adhesive adhering the polymer sheet to the mold tool.

A method of making a composite part comprises covering a mold tool for a composite part with a parting film, the parting film comprising a polymer sheet and a pressure sensitive adhesive. The parting film is positioned so that the polymer sheet is between the mold tool and the pressure sensitive adhesive. At least one layer of pre-preg is layed up on the parting film covering the mold tool to form a layed-up composite part. The pre-preg comprises an adhesive. The layed-up composite part is removed from the parting film.

Methods for making and curing resin-based adhesives are disclosed using encapsulated amine accelerators activated by providing ultrasonic energy.

The present disclosure is directed to a thermoresponsive adhesive material. The material comprises a linear, phase-separated polymer having fluorinated polymer units and hydrophobic polymer units. The fluorinated polymer units and the hydrophobic polymer units are randomly ordered along the polymer. The hydrophobic polymer units include a first hydrophobic polymer unit and a second hydrophobic polymer unit. The first hydrophobic polymer unit is chosen from acrylate units or methacrylate units each substituted with one or more linear alkyl groups, linear alkenyl groups or a combination thereof, where at least one of the linear alkyl groups or alkenyl groups has 16 to 20 carbon atoms. The second hydrophobic polymer unit is chosen from acrylate units or methacrylate units each substituted with one or more linear alkyl groups, linear alkenyl groups or a combination thereof, where at least one of the linear alkyl or alkenyl groups of the second hydrophobic polymer unit has 5 to 14 carbon atoms. A peak adhesive strength of the thermoresponsive adhesive material is modifiable and reversible with a change in temperature. Methods of making thermoresponsive adhesive materials, methods employing thermoresponsive adhesive materials and self-adhesive objects that include thermoresponsive adhesive materials are also disclosed.
