“…Limited research has been performed on 316L stainless steel coatings using cold spray (Ref [18][19][20][21][22][23][24]. The formation of recrystallized, nanoscale grains near particle interfaces in the as-sprayed 316L coating (N 2 and He-sprayed) was observed through TEM analysis (Ref 18) while EBSD analysis revealed a fully recrystallized microstructure after annealing (compressed air-sprayed coatings) (Ref 23).…”

In this study, the effects of heat treatment on the microstructure and mechanical properties of cold sprayed stainless steel 316L coatings using N 2 and He as propellant gases were investigated. Powder and coating characterizations, including coating microhardness, coating porosity, and XRD phase analysis were performed. It was found that heat treatment reduced porosity, improved inter-particle bonding, and increased ductility. XRD results confirmed that no phase transformation occurred during deposition. Significant increase in UTS and ductility was observed for the annealed specimens obtained with nitrogen propellant, whereas little changes were observed for the helium propellant produced specimen.

“…An alternative to improve the performance of these coatings is the use of heat treatment as previously reported 63,66,75,78,81,84,93,96,97 . , stainless steel coatings 60,100 and Inconel 718 101 . Moreover, the mechanical properties (tensile strength, elongation) and corrosion resistance of cold-sprayed coatings may also be improved by applying heat treatments 60,94 .…”

“…It is evident from these results that closure of pores and cracks, with reduction in grain boundaries, due to the heat treatment, is responsible for the increase of corrosion resistance 59 . Sundararajan et al 60 demonstrated that the corrosion resistance of cold-sprayed SS 316L coatings increases as a function of the temperature of heat treatment for different exposure times in 0.1 mol L -1 HNO 3 . As-prepared condition showed a microstructure characterized by weakly / unbounded intersplat boundaries and high porosity.…”

ABSTRACT:In this review, the beginnings and evolution of the cold gas spray (CGS) technique are described, followed by the main fundamental aspects of the technique together with a description of the several spraying systems up to date. Sequentially, the main spray parameters and their influence on the properties of the coatings are reported. Afterwards, the most important methodologies for preparing the feedstock powders to be sprayed, the effect of the powder composition, microstructure, particle size and shape on the properties of the coatings are discussed. The nature of the spray gun and nozzle, and the substrate pre-treatments were also discussed. With regard to microstructure and properties, the chemical and physical characterization of the coatings and the performance in protecting the substrates against corrosion together with some mechanical properties are presented and compared. The lacking systematic studies about the great part of investigated systems is the main drawback to compare the published results. Closing this review, the main applications, and the potentialities of the CGS coatings are evidenced.

“…The research issues concerning the production of coatings are the most important directions of surface engineering development, ensuring the obtainment of coatings of high usable properties in the scope of mechanical characteristics and corrosion resistance (Yu et al, 2009;Cheng et al, 2009;Kao, 2009;Mao et al, 2009;Sundararajan et al, 2009). Giving new operating characteristics to commonly known materials is frequently obtained by laying simple monolayer, multilayer or gradient coatings using PVD methods (Dobrzanski et al,2005;Lukaszkowicz & Dobrzański, 2008).…”
