“…Aluminium coatings have been successfully deposited on different substrates by CS. Previous studies [6][7][8][9][10][11] have described deposition mechanism, preparation technology and surface characteristic of CS aluminium coating. The corrosion performance of CS aluminium coating has also been studied.…”

High velocity arc spraying and cold gas dynamic spraying were applied to prepare the aluminium coating, and electrochemical impedance spectroscopy measurement in combination with scanning electron microscopy analysis of corrosion surface and X-ray diffraction results of corrosion product were used to compare the corrosion behaviour of these two coatings. It was found that there was sparse and porous corrosion product covering on the surface of the arc sprayed aluminium coating through which the Cl 2 can penetrate into the inner coating interface. In contrast, the surface of the cold sprayed aluminium coating after immersion was less porous and tended to seal the pores in the coating. This kind of structure can obstruct the penetration of corrosion medium into the inner coating surface and reduce the corrosion rate to a certain extent. In addition, the diffusion impedance O was introduced in the electrochemical impedance spectroscopy modelling for the purpose of getting good fitting results.

“…Due to the continuous impact of subsequent particles, the deposited coating experienced a strong tamping effect and produced a large deformation to eliminate the gaps between particles. Meanwhile, the continuous impact of subsequent particles also formed a micro-forging effect on the surface to improve the strength [43] of the coating.…”

“…eliminate the gaps between particles. Meanwhile, the continuous impact of subsequent particles also formed a micro-forging effect on the surface to improve the strength [43] of the coating. As can be seen from Figure 3, the carrier gas temperature had a great influence on the coating's porosity.…”

Titanium coating on a steel substrate by surface technology can improve the corrosion resistance of steel. In this paper, the titanium TA2 coating was deposited on X80 steel by cold spraying equipment with a low-cost irregular powder. The effects of the carrier gas temperature on the microstructure, microhardness, wear resistance, adhesion and corrosion resistance of titanium coatings, especially in a deep sea environment, were studied by methods of porosity analysis, thermal field emission scanning analysis, energy spectrum analysis, Vickers hardness tests, bonding strength tests, friction and wear tests and electrochemical tests. The results showed that as the carrier gas temperature increased from 300 °C to 900 °C, the porosity of the coating decreased to 0.93%, and the hardness and bonding strength of the coating increased to 247 HV0.5 and 46.7 MPa, respectively. With the increase in hydrostatic pressure from 0.1 MPa to 40 MPa, the dimensional blunt current density of the titanium coating with 0.93% porosity was still in the order of 10−7 A·cm−2 with the cast titanium TA2.
