Thermal Spray coatings of highly reinforced aluminium matrix composites with sol gel silica coated sic particles
Surface & Coatings Technology, 2007Co-Authors: B. Torres, Marcelo Campo, Alejandro Ureña, Joaquin RamsAbstract:Abstract Low porosity coatings made of aluminium matrix composites reinforced with SiC particles were fabricated by a Thermal Spray method. The initial Spray material used was a mixture of aluminium powder and SiC particles which were directly fed in the Thermal Spray gun flame without any previous sintering. Sol–gel silica coatings with different structural characteristics were deposited on the SiC particles before mixing with aluminium powder to increase the wettability of reinforcement by molten aluminium during the Spray while avoiding the appearance of any degrading reaction between aluminium and SiC particles. The Thermal Spray coatings were manufactured with different reinforcement degrees from 4 vol.% to 47 vol.% SiC using mixtures of sol–gel coated SiC particles in the 20% to 70% range. Porosity was in most cases below 1%. The relevance of using sol–gel coatings on reinforcement particles and of the sol–gel structure is analysed.

Thermal Spray forming of titanium and its alloys
Titanium Powder Metallurgy, 2020Co-Authors: Christopher C. BerndtAbstract:Abstract Thermal Spray is a versatile process that is used to deposit a wide range of materials for applications that include aerospace, biomedical, electronic devices, and repair and maintenance of infrastructure. This chapter reviews the deposition of titanium and titanium alloys by Thermal Spray processes, including plasma Spray, wire arc Spray, high-velocity oxygen fuel, and detonation Spray. Titanium-based powder with certain characteristics that qualifies as Thermal Spray feedstock is discussed with considerations to the quality of the coatings and components. The technological aspects, phases identified, and parameter optimization for each Thermal Spray process differ. Thus, the titanium-based products also reflect microstructural differences that impact the potential applications. This chapter guides the reader in choosing the appropriate process for an intended application.

The 2016 Thermal Spray Roadmap
Journal of Thermal Spray Technology, 2016Co-Authors: A. Vardelle, Athanasios C. Bourtsalas, Jörg Oberste Berghaus, Jeffrey Brogan, Jun Akedo, Hossein Ashrafizadeh, Christopher C. Berndt, Christian Moreau, Maher I. Boulos, Ali DolatabadiAbstract:Considerable progress has been made over the last decades in Thermal Spray technologies, practices and applications. However, like other technologies, they have to continuously evolve to meet new problems and market requirements. This article aims to identify the current challenges limiting the evolution of these technologies and to propose research directions and priorities to meet these challenges. It was prepared on the basis of a collection of short articles written by experts in Thermal Spray who were asked to present a snapshot of the current state of their specific field, give their views on current challenges faced by the field and provide some guidance as to the R&D required to meet these challenges. The article is divided in three sections that deal with the emerging Thermal Spray processes, coating properties and function, and biomedical, electronic, aerospace and energy generation applications.

Nanocomposite coatings: Thermal Spray processing, microstructure and performance
International Materials Reviews, 2015Co-Authors: Jo Ann Gan, Christopher C. BerndtAbstract:AbstractThe processing of nanomaterials and nanocomposites has advanced since the 1990s. The growth and opportunities afforded by this technological domain is evident through the trends of research and development (R&D) funding, Science Citation Index (SCI) publications, and patent applications presented in this paper. This article reviews the current state for the development of Thermal Sprayed nanocomposite coatings. The types of nanocomposite Thermal Spray feedstock materials that are available commercially, as well as those currently in the development phase, are critically assessed. The Thermal Spray approaches to deposit nanocomposite coatings are discussed, including the conventional plasma Spray and high velocity oxygen fuel (HVOF) processes and the more recently developed cold Spray, suspension Thermal Spray (STS), and solution precursor Thermal Spray (SPTS) processes. These processes are assessed in relation to their deposition mechanisms and the specific nanocomposite materials associated with each technique. The unique microstructure of the coatings deposited by each method is highlighted in relation to process and compositional control. The exceptional attributes of nanocomposite coatings, such as mechanical strength and toughness, wear resistance, thermophysical, and electrical properties, are also presented together with specific applications.

Thermal Spray Maps: Material Genomics of Processing Technologies
Journal of Thermal Spray Technology, 2013Co-Authors: Noppakun Sanpo, Mitchell L. Sesso, Christopher C. BerndtAbstract:There is currently no method whereby material properties of Thermal Spray coatings may be predicted from fundamental processing inputs such as temperature-velocity correlations. The first step in such an important understanding would involve establishing a foundation that consolidates the Thermal Spray literature so that known relationships could be documented and any trends identified. This paper presents a method to classify and reorder Thermal Spray data so that relationships and correlations between competing processes and materials can be identified. Extensive data mining of published experimental work was performed to create Thermal Spray property-performance maps, known as “TS maps” in this work. Six TS maps will be presented. The maps are based on coating characteristics of major importance; i.e., porosity, microhardness, adhesion strength, and the elastic modulus of Thermal Spray coatings.
