“…The authors suggested the reasons might be due to high velocities of powder particles or due to strain hardening effect of the grit blasting of base materials before the coating formulation. 24 Sundararajan et al 34 and Hidalgo et al 4 also discussed the similar observations in their studies. Therefore, it can be concluded that the given additions were, in general, useful to enhance the average microhardness of the base NiCrFeSiB coating.…”

NiCrFeSiBC/Cr 3 C 2 composite coatings were developed on to GrA1 boiler steel by high velocity oxy fuel spray process. The aim was to develop the novel composite coating by finding optimum concentration of Cr 3 C 2 in NiCrFeSiBC matrix, which further possesses the superior solid particle erosion resistance. The mechanical and microstructural properties of the developed coatings were critically examined. The as sprayed coatings were characterised by X-ray diffraction, SEM/ energy dispersive spectroscopy analyses. The coatings exhibited characteristic splat-like morphology with the presence of micropores, unmelted and semimelted particles and inclusions. The adhesion strength of the developed coatings was also determined. The physical properties like surface roughness, porosity and microhardness of the as sprayed coatings have also been reported. The blending resulted into the formation of composite-like coatings where, the Cr 3 C 2 phase was nearly uniformly distributed into the NiCrFeSiBC matrix. The results have been discussed with respect to the existing literature.

“…Water-cooled components, in the off-gas duct systems such as pans, roofs, boxes and panels, are subjected to high-velocity combustion gases that contain a number of corrosives chemicals that condense and attack the heat transfer surfaces. Coatings used are those developed for high-temperature wear and corrosion resistance (see the articles of Wang and Verstak (1999), Higuera Hidalgo et al (2001), Sidhu et al (2005), (2006), Kaushal et al (2011)). …”

“…One method to lower friction and maintain good abrasive wear resistance is to add some low friction compounds to the hardmetal coating (Ref [6][7][8][9][10]. The low friction compound can be a solid lubricant (MoS 2 , CaF 2 , BaF 2 , etc.)…”

HVOF spraying was used to prepare coatings from mechanical blends of Cr 3 C 2 -25NiCr and NiCrBSi powders. The aim of this study is to study the tribological behavior of coatings prepared from such powder blends. The coatings were studied under dry sliding conditions particularly at high temperatures. Tribological properties of the coatings were characterized using a specific hot-button tribological tester at the temperature of 300°C in air, and a pin-on-disk test at room temperature. Addition of NiCrBSi resulted in coatings, which showed low coefficient of friction in high temperatures, and in high levels of contact pressure and sliding speed.
