Microstructures of the powder and coating were investigated by X-ray diffraction (XRD), scanning election microscopy (SEM), and transmission electron microscopy (TEM), and a quantitative determination of the adhesion strength of the coating was calculated by combination of modified four-point bending (4PB) test and finite element analysis (FEA) simulation. The results show that the coating mainly consists of ternary transition metal boride matrix phases (CoMo2B2, MoCoB) and binary borides (MoB and CrB). Nanocrystalline grains with a size of 50–100 nm were observed in the coating. The average energy release rate and phase angle are 191.2 J m−2 and 41.7º, respectively, which show strong bond strength compared to other reported values.

Dry abrasion property of TiN-matrix coating deposited by reactive High Velocity Oxygen Fuel (HVOF) spraying / Zhengping Mao in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 7, N° 2 (03/2010)  

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 7, N° 2 (03/2010) . - p. 253-259 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.
