Titanium boron composite coatings with superior wear performance were selected for use in materials experiments on the International Space Station. The titanium-boron nitride composite coatings were prepared using an atmospheric plasma spray technique from engineered composite powders. The coatings were subjected to extensive characterization and tribological studies. The results show tremendous improvement in the wear performance.

This article describes work being done at the University of Limoges to develop thermal spray coatings for use in new nuclear power plant designs.

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.

This article presents a brief overview of thermally sprayed thermal barrier coatings (TBCs) used in gas turbines that generate electrical power.

What needs to be discovered, learned, and understood to advance thermal spray beyond existing practices? Is revenue a realistic indicator of progress and advancement or is it just a framework for a much bigger picture? This article reviews some past successes, failures, and unrealized potentials of industrial and manufacturing outcomes and provides details of the knowns and unknowns of the thermal spray portfolio.

This article discusses some of the newer thermal barrier coating materials being considered for use in gasified coal-based turbines and how they compare with conventional materials in terms of bond coat oxidation and topcoat damage due to particle erosion and molten ash deposits.

Thermal barrier coatings (TBCs) with segmented or cracked microstructures exhibit enhanced thermal cyclic behavior and erosion resistance, along with improved application economics, over conventional TBCs.

Vacuum plasma and low pressure plasma spray technologies each provide unique solutions for achieving superior properties in metallic coatings that require low oxide content and high density. Applications include various turbine engine components, as well as biomedical and electronics components.

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.

Radio frequency inductively coupled plasma (RF-ICP) spraying is shown to be a promising method for producing oxidation-resistant W and W-Cr coatings on plasma-facing surfaces in fission and fusion reactors.

Thermal-spray and solution-based synthesized coatings offer improved efficiency and durability than currently used coatings in concentrating solar power receiver applications.

A new single-step plasma-assisted gas atomization process for metal powder manufacturing can reduce carbon footprint by over 99% compared to traditional methods. This technology uses scrap metals as feedstock, eliminating the need for virgin ores while meeting ASTM/AMS powder quality specifications. Beyond environmental benefits, the innovation addresses material scarcity that has historically constrained the additive manufacturing industry while mitigating supply chain delays and market uncertainties. The process supports manufacturers in achieving environmental goals through significant emissions reduction and localized sourcing.

This article, the first in a two-part series, explains how powder metallurgy presents a cost-effective alternative to conventional titanium fabrication processes. It reviews the characteristics of different types of titanium powders and compares and contrasts near-net shape (NNS) production techniques, including conventional press-and-sinter, cold isostatic pressing (CIP), hot isostatic pressing (HIP), CIP-sinter, and CIP-sinter-HIP (CHIP). Other titanium production methods are covered in Part 2, which is scheduled for the October 2012 issue of AM&P .
