“…It enables to fabricate nonoxide and nitride ceramic coatings. Among these coatings some nitrides including titanium nitride (TiN) ( Ref 1,2), silicon nitride (Si 3 N 4 ) (Ref [3][4][5], aluminum nitride (AlN) (Ref [6][7][8][9][10], and iron nitride (Fe 4 N) ( Ref 11) had attracted much attention due to their excellent properties. We interested in aluminum nitride, thus it has emerged as an important material for several structural and electrical applications (Ref [12][13][14][15] due to its outstanding electrical and mechanical properties.…”

Feedstock powder characteristics (size distribution, morphology, shape, specific mass, and injection rate) are considered to be one of the key factors in controlling plasma-sprayed coatings microstructure and properties. The influence of feedstock powder characteristics to control the reaction and coatings microstructure in reactive plasma spraying process (RPS) is still unclear. This study, investigated the influence of feedstock particle size in RPS of aluminum nitride (AlN) coatings, through plasma nitriding of aluminum (Al) feedstock powders. It was possible to fabricate AlN-based coatings through plasma nitriding of all kinds of Al powders in atmospheric plasma spray (APS) process. The nitriding ratio was improved with decreasing the particle size of feedstock powder, due to improving the nitriding reaction during flight. However, decreasing the particle size of feedstock powder suppressed the coatings thickness. Due to the loss of the powder during the injection, the excessive vaporization of fine Al particles and the completing nitriding reaction of some fine Al particles during flight. The feedstock particle size directly affects on the nitriding, melting, flowability, and the vaporization behaviors of Al powders during spraying. It concluded that using smaller particle size powders is useful for improving the nitriding ratio and not suitable for fabrication thick AlN coatings in reactive plasma spray process. To fabricate thick AlN coatings through RPS, enhancing the nitriding reaction of Al powders with large particle size during spraying is required.

“…However, the coating was mainly composed of the residual Ti and some TiN, Ti 2 N. Akira Kobayashi [1], using a gas tunnel-type plasma jet, prepared a TiN coating whose thickness was over 200 mm. In addition, Wenran Feng [12,13] especially studied the microhardness and tribological properties of the reactive plasmasprayed TiN coating; E. Galvanetto [14] investigated the formation of titanium nitrides during the reactive spraying of titanium by means of XRD and XPS.…”

“…The friction coefficient decreases with the increment of applied load; however, the friction coefficient decreases a little when the applied load exceeds 300 N. The variable trend of the friction coefficient is similar to the research investigated in the literature. 15 From these two diagrams, it can be concluded that the TiN-matrix coating possesses excellent abrasion resistance and self-lubricating properties, especially under high applied load. It also shows that the friction coefficient may arrive at a stable value, which cannot decrease with the increment of applied load.…”

“…The abrasion resistance of TiN coating deposited by reactive thermal spraying, which is the most important performance in realistic applications, is rarely studied. Wenran Feng et al 15 did some research on the tribological properties of TiN coatings prepared by reactive plasma spraying. In addition, TiN coatings prepared by reactive HVOF spraying were characterized by a considerable efficiency, significant hardness, and relatively good toughness.…”

A TiN-matrix coating with a thickness of about 400 lm 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-onring 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 TiN 0.3 , minor phases of Ti 2 O 3 , and TiO 2 . 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 selflubricating property can improve the antiwear property of the substrate significantly.
