Nanostructured Thermal Spray Feedstocks:the Next Generation of Engineered Coatings

摘要

This paper presents an overview of the recent research activities at lnframat(R)Corporation(IMC)on the development of thermal spray processes for nanostructured coatings, which enable improved performance and durability of coated components. Designed multifunctional nanocoatings present unprecedented opportunities for advances in materials properties and performance for a broad range of engineered surface applications.The technology described in this paper involves the reconstitution of individual nanoparticles into sprayable micron-sized agglomerates, followed by the thermal spray of these agglomerated granules into a high performance nanostructured coating.One important feature of the nanostructured coatings is their improved toughness,contributing to a significant improvement in wear resistance.
