Thermal spraying is being incorporated into more manufacturing processes where its primary role is to deposit a layer of material or a free-standing structure that has a functional, rather than a passive, role. Examples include thermally sprayed membranes, electrodes, antennas, thermocouples, inductors, and electrical contacts.

The use of coatings to enhance the performance of components is one of the most powerful tools in materials engineering. This article highlights some examples of how thermal spray technologies are used to enhance surface properties for selected applications and industries.

More than one hundred participants attended a special workshop at Stony Brook’s Center for Thermal Spray Research in celebration of its 25-year contribution to the industry. This article reviews highlights of the workshop, including several key presentations from thermal spray experts and notables in the field.

The next generation of metal additive manufacturing leverages the advantages of cold spray to offer promising options for applications in aerospace, automotive, and biomedical engineering.

A multicomponent thermal spray coating system resists pick-up of contaminants that can cause flaws on heat treated strip surface.

A high-velocity oxyfuel (HVOF) spray gun that operates on conventional (gas or kerosene) fuels as well as liquid-gas combinations is shown to be capable of producing MCrAlY bond coats consisting of a rough surface layer (for adhesion) on a dense base (for oxidation protection).

An integrated strategy for the development of thermally sprayed functional oxide coatings is presented in this article. Strontium-doped lanthanum manganite (LSM), a prototypical functional oxide, was selected to demonstrate the approach.

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.

The absence of standards and a common vocabulary are an obstacle when it comes to evaluating the structure of thermal spray coatings. However, proper sectioning and mounting of metallographic specimens helps ensure that the images obtained accurately reflect the coating structure and the information that can be derived from it.

Corrosion under insulation (CUI) exacts a heavy toll on petrochemical processing equipment, particularly piping, where leaks and safety risks associated with CUI drive maintenance costs. This article assesses the high cost of CUI and explains how the petrochemical industry is working to reduce those costs by protecting components with thermal spray aluminum (TSA) coatings and by employing complementary pipe welding procedures.

This article presents an overview of the use of thermal spray technology at The Boeing Co., dating back to 1968 when the first thermal spray specification, "Plasma Flame Spray Coating," was released. It also discusses anticipated needs based on industry trends.

Thermal spray technology is increasingly being used in alternative energy applications such as solid-oxide fuel cells, solar panels, and wind and hydropower turbines.

This article provides a brief review of thermal spray technology along with examples of where and how it used in steelmaking equipment and operations.

This article describes a multistation high-volume production cell in which molybdenum coatings are applied to automotive transmission components by wire flame spraying using a combination of acetylene, oxygen, and air.

For those who are active within the thermal spray industry, 2017 offered a dramatic mix of jubilation and concern over conditions within the global thermal spray market. This article briefly reviews some of the market factors influencing the industry in 2017 and future outlook.

Stony Brook celebrates a milestone by reflecting on its Center for Thermal Spray Research from the early years of growth and expansion to the development of an industrial consortium.

Developing a disciplined approach to standardizing special processes and introducing new technologies is key to eliminating defects in thermal spray applications.

This article describes a new document on methods to test the bond strength of thermal spray coatings that was developed and released by the ASM Thermal Spray Society Accepted Practices Committee on Metallography. This practice clarifies details of ASTM C633 requirements and provides examples of best practices confirmed by hundreds of tests performed wordwide
