Publication number: 20210254229Abstract: Additive-based electroforming manufacturing methods for producing turbomachine components and other metallic articles are provided, as are metallic articles manufactured utilizing such manufacturing methods. In various embodiments, the method includes the step or process of additively manufacturing a sacrificial tooling structure having a component-defining surface region. A metallic body layer or shell is deposited over the component-defining surface region utilizing an electroforming process such that a geometry of the component-defining surface region is transferred to the body layer. The tooling structure is chemically dissolved, thermally decomposed, or otherwise removed, while the metallic body layer is left substantially intact. After tooling structure removal, the metallic body layer is further processed to complete fabrication of the metallic component.Type: ApplicationFiled: October 7, 2020Publication date: August 19, 2021Applicant: HONEYWELL INTERNATIONAL INC.Inventors: Qiang Li, Gangmin Cao

Patent number: 11041252Abstract: Methods for depositing wear resistant NiW plating systems on metallic components are provided. In various embodiments, the method includes the step or process of preparing a NiW plating bath containing a particle suspension. The NiW plating bath is prepared by introducing wear resistant particles into the NiW plating path and adding at least one charged surfactant. The first type of wear resistant particles and the first charged surfactant may be contacted when introduced into the NiW plating bath or prior to introduction into the NiW plating bath. The at least one charged surfactant binds with the wear resistant particles to form a particle-surfactant complex. The wear resistant NiW plating system is then electrodeposited onto a surface of a component at least partially submerged in the NiW plating bath. The resulting wear resistant NiW plating system comprised of a NiW matrix in which the wear resistant particles are embedded.Type: GrantFiled: March 22, 2018Date of Patent: June 22, 2021Assignee: HONEYWELL INTERNATIONAL INC.Inventors: James Piascik, Gangmin Cao, Amer Aizaz, Jingkang Lv, Bahram Jadidian
