A method for assembling a shear web assembly of a wind turbine includes providing at least one spar cap. The method also includes forming a spar connecting member of a thermoplastic material via additive manufacturing. Further, the method includes securing the spar connecting member to the spar cap. Moreover, the method includes providing a shear web, forming a web connecting member of a thermoplastic material via additive manufacturing, and securing the web connecting member at a first end of the shear web. In addition, the method includes interconnecting the web connecting member and the spar connecting member at a joint. Thus, the method further includes heating the joint to secure the web connecting member and the spar connecting member together.

An article includes a substrate formed of a molybdenum-based alloy. A barrier layer is disposed on the substrate. The barrier layer is formed of at least one noble metal.

A thermal barrier-coated Ni alloy component includes: a substrate made of a Ni alloy containing Al; an intermediate layer formed on a surface of the substrate; and a thermal barrier layer made of a ceramic and formed on a surface of the intermediate layer. The intermediate layer includes a layer, which is formed from a -Ni.sub.3Al phase on the surface on the thermal barrier layer side, and contains Pt.

An article includes a substrate formed of a molybdenum-based alloy. The molybdenum-based alloy has a composition that includes molybdenum, silicon, and boron. A barrier layer is disposed on the substrate. The barrier layer is formed of at least one noble metal.

A system for securing a component for an electrically-driven process is disclosed. The system includes a mai015134n body having an opening, a retention slot configured for retaining the component, and a channel. The system includes a fastener extending through the opening in the main body, and an insert inserted into the channel. The system has a shank movably coupled to the fastener and configured to contact the insert. The insert is configured to maintain electrical contact between the shank and the component when the component is retained within the retention slot.

A method of forming a thermal barrier coating onto a surface of a ferrous alloy or nickel alloy component part involves depositing a layer of hollow microspheres to a surface of the component part or to a previously deposited layer of hollow microspheres through heating and cooling of a metallic precursor setting layer composed of copper, a copper alloy, or a nickel alloy. Once deposited in place, the layer(s) of hollow microspheres are heated to sinter the hollow microspheres to each other and to the surface of the ferrous alloy or nickel alloy component part to form an insulating layer.

A coating system for a surface of a superalloy component is provided. The coating system includes a MCrAlY coating on the surface of the superalloy component, where M is Ni, Fe, Co, or a combination thereof. The MCrAlY coating generally has a higher chromium content than the superalloy component. The MCrAlY coating also includes a platinum-group metal aluminide diffusion layer. The MCrAlY coating includes Re, Ta, or a mixture thereof. Methods are also provided for forming a coating system on a surface of a superalloy component.

A system and method for producing a rigid, heat-resistant part, such as a superalloy, via electrodeposition. The method can include the steps of coating a secondary alloy particulate with a superior alloy, forming a pre-coated particulate, dispensing a quantity of the pre-coated particulate into a container of an electrolytic solution, and applying a charge to the electrolytic solution such that the pre-coated particulate is electrodeposited onto a cathode or an external casing of the cathode. The pre-coated particulate can include particulate of non-uniform size and/or shape. The secondary alloy particulate is protected in the catalytic solution by the superior alloy coated thereon, such as nickel, iron, cobalt, and/or copper. The method also includes a step of vibrating or agitating the electrolytic solution before and/or during applying the charge to the electrolytic solution for even distribution of the pre-coated particulate onto the cathode or an external casing thereof.
