Characterization of Tribological Quasicrystalline Composite Coatings
(Deutscher Verband für Schweisstechnik, 2002-03-06) Román, A.; Agüero, A.; De Miguel, C.; García de Blas, F. J.; Longo, Federico; Muelas Gamo, Raúl; Sánchez, A.
Quasicrystalline (QC) alloys constitute a family of materials with low coefficient of friction, high hardness, and high yield strength under compressive stress. This paper examines the characteristics of QC composite coatings deposited by LPPS and HVOF spraying. It compares the coatings based on phase distribution and microstructure. Both compositions studied are extremely wear resistant, but their friction properties require further development. Paper includes a German-language abstract.
