This article describes the design and operation of a high-deposition rate plasma nozzle developed for ambient pressure spraying.

Innovations built into a new plasma spray torch address shortcomings of previous axial injection equipment.

Renewed interest in a NASA-developed material known as Triboglide has led to a study of the friction and wear properties of HVOF-sprayed Triboglide coatings and close variants. This article describes the coating process, examines coating cross-sections, and presents and analyzes the results of high-temperature pin-on-disc wear tests.

Triboglide coatings offer enhanced wear resistance in applications like air foil bearings, actuators, and wear components where oil-based lubrication is scarce. They exhibit excellent wear and friction properties compared to other commercially available coatings.

This case study reviews the considerations in applying plasma spray thermal barrier coatings on augmenters used in military aircraft turbine engines to extend their service life.

New thermal spray methods optimized for the production of functional coatings are bridging the gap between traditional thermal spraying and thin-film deposition technologies. Two such methods, one known alternately as very low pressure plasma spraying (VLPPS) or plasma spray-physical vapor deposition (PS-PVD) and one called thin-film thermal spray chemical vapor deposition (CVD), are briefly reviewed here.

This case study addresses the use of online diagnostic tools to adjust spray parameters to ensure consistent results.

Cold spray is an effective method of depositing a variety of temperature-sensitive materials in specialized applications, such as high-value aerospace component repair. The use of cold spray has seen a significant increase in the repair and restoration of housings for integrated drive generators used in commercial aircraft.

This article reports on work at the Center for Thermal Spray Research over the past 25 years to develop and commercialize a new technology for digital printing of mesoscale circuits directly from a CAD file onto plates, cylinders, and complex 3D components and structures. With the evolution of cold spray technology and new powder materials, as well as advancements in control and robotics, innovative thermal spray applications are on the horizon.

Cold spray technology provides a multidisciplinary approach to additive manufacturing at the intersection of science and art. This article describes the novel use of cold dynamic spray technology to create a large and complex 3D artwork that incorporates six different metals.

Coating development using cold gas spray technology demonstrates the feasibility of bonding polymers to metal substrates and metals to polymer composite substrates with good adhesion. The examples addressed are polyetheretherketone (PEEK) coatings on steel and aluminum substrates and metallic coatings on carbon fiber reinforced polymer (CFRP) composites.

This article is the second in a two-part series on cost-saving methods for the production of titanium components. Part 1, published in the September 2012 issue of AM&P , covered a number of powder metallurgy techniques, including press-and-sinter and both cold and hot isostatic pressing. Other near-net shape processes are described here, including additive layer manufacturing (ALM), metal injection molding (MIM), and spray deposition (SD). Examples are also given showing how titanium PM parts compare with cast and wrought components.

3D printing of organic and inorganic materials requires special consideration in both material selection and the process used. This article provides an overview of the the six major processes used for 3D bioprinting: extrusion bioprinting, inkjet printing, selective laser sintering, stereolithography, laser-induced forward transfer bioprinting, and two-photon polymerization.

The development of polymers, traditionally neglected in fusion materials research, is crucial to the success of commercial fusion energy. This article provides an overview of the materials science and technology challenges that will need to be addressed to develop the mechanically “soft” materials that will serve functional needs in a fusion pilot plant.
