The cross sections of the coating specimens are examined on a Hitachi Model S-570 scanning electron microscope (SEM), which investigates the quality and measures the geometry of the coatings. The mechanical properties of the coatings and the substrate are determined in the cross sections using the nano-indentation technique. The cracking behavior of the coatings under different indentation loads is investigated using a Vickers hardness tester. Three-dimensional finite element analysis (FEA) simulation of the Vickers indentation test is conducted to determine the stress fields in the coating/substrate systems in order to understand the fracture mechanisms of the coatings under the indentation loads using the ABAQUS software package. The FEA stress results are in good agreement with the experimental observation of Vickers indentation.

Titre : Dry abrasion property of TiN-matrix coating deposited by reactive High Velocity Oxygen Fuel (HVOF) spraying Type de document : texte imprimé Auteurs : Zhengping Mao, Auteur ; Jing Ma, Auteur ; Jun Wang, Auteur ; Baode Sun, Auteur Année de publication : 2010 Article en page(s) : p. 253-259 Note générale : Bibliogr. Langues : Américain (ame) Tags : 'Pulvérisation réactive' 'Projection flamme oxygène-carburant haute vitesse' (HVOF) 'Abrasion sèche 'Auto-lubrifiant' 'Revêtement nitrure titane' Index. décimale : 667.9 Revêtements et enduits Résumé : A TiN-matrix coating with a thickness of about 400 μm was prepared by reactive high velocity oxygen fuel (HVOF) spraying on carbon steel in air. The phase composition, microhardness, and antiabrasion properties of the coating were investigated using x-ray diffraction (XRD), an energy dispersive spectrometer (EDS), a scanning electron microscope (SEM), a Vickers microhardness tester, and block-on-ring abrasive equipment. The abrasion mechanism of TiN-matrix coating under dry abrasion conditions was also discussed. The results indicate that the composition of the coating is main phases of TiN and TiN0.3, minor phases of Ti2O3, and TiO2. The TiN-matrix coating possesses high microhardness and relatively good toughness. Furthermore, the friction coefficient of the coating decreases with the increment of applied load. The interstratified distribution of titanium oxides can act as a solid lubricant during the wear test. The main abrasion mechanism of the TiN-matrix coating is adhesion wear. In addition, the coating with self-lubricating property can improve the antiwear property of the substrate significantly.
