“…To reduce the porosity and to improve the tribological behavior of the ceramic coatings, optimization of processing parameters for thermal spraying has already been investigated [3][4][5]. It includes heat treatments using furnace (risk of new phases of materials are often formed and long annealing time needed [6]) and laser sintering (possibility of formation of micro cracks owing to the rapid heating and cooling rates [7][8][9][10]). The objective of sealing by impregnation for high temperature wear-and corrosion-resistant ceramic coatings is to reduce as much as possible the open pores and cracks that are connected to the surface, because the highest wear and corrosion resistance of ceramic based coatings can be achieved only with a dense structure [11].…”

Solvo-thermal treatment was used to chemically densify thermalsprayed oxide based coatings. This allows to reduce significantlyits porosity whilst it improves the cohesion and hardness. As aconsequence, this leads to a better thermal shock and wearresistance. This innovative process has been successfully used toimprove the corrosion resistance against liquid aluminum alloyswhere coatings face combined chemical, thermal and mechanicalloads.

“…One of the primary reasons for the material failure of metal equipment is corrosion, which seriously affects the service life and service reliability of equipment and causes huge economic losses [1][2][3][4][5]. Using coatings to enhance the surface characteristics of materials is an efficient technique to lengthen the service life of components.…”

The Fe-based austenite-containing composite coatings with various contents (3 vol.%, 6 vol.%, 9 vol.%, 12 vol.%) of austenite powder additions were created by supersonic plasma spraying on 45 steel substrates. The microstructure, phase composition, microhardness, and porosity of the composite coatings were examed. Moreover, special attention was paid to the effect of austenite powder on the corrosion resistance of the austenite-containing composite coatings. The results found that the addition of austenite powders could significantly improve the corrosion resistance of Fe-based coatings, which is mainly due to three correlated phenomena caused by the austenite particles. First, austenite particles significantly reduce the porosity of the austenite-containing composite coatings and form a denser coating structure due to their low melting point and good chemical compatibility with the Fe-based alloy. Further, austenite particles help to refine the grains and increase the grain boundary density. Last but not least, austenite particles help to generate more diffusely distributed second phases in the coating, improving the chemical homogeneity and hardness of the coating.
