“…Analyzing the different morphologies of the obtained layer for various substrates, the authors underlined the fact that ASI phenomena occur during the CS deposition. Schmidt et al [34] give comparable conclusions for deposited TiO 2 microparticles onto the Ti substrate. These studies present the dependence of the substrate material characteristics, which exhibits mechanical interlocking or ASI and promotes the ceramic coating build-up.…”

MAX phase compounds offer an attractive mixture of ceramic–metallic properties due to their covalent ionic–metallic nature. Since their discovery, a great interest was attributed to their synthesis and potential applications, but the processing of pure compounds as coatings for industrial large-scale application is still considered a challenge. To date, a limited number of papers have evaluated the build-up of MAX phase coating by cold spray (CS), a novel cost-effective and productive spray technology used in both areas of research and industry. Employing CS, the hot gas-propelled material particles have ballistic impingement on a substrate where they undergo plastic deformation. Because of the brittleness, internal delamination, and limited deformability, the deposition of the pure MAX phase is rather challenging. This paper presents the building-up ability of dense MAX-phase coatings by CS with retained structures and compositions, in close relation with the substrate characteristics and phase composition that influences the dual character ceramic–metallic behaviour. Besides recent literature, the originality of this research consists of pioneering deposition of Ti3AlC2 that emphasizes the ceramic–metallic character influenced by the particle speed and the mechanical properties of both substrate and compound.

“…Schmidt et al used 0.1-10 µm of TiO 2 particles that were cold sprayed onto the flat polished surface of a titanium substrate. They identified that the plastic deformation of the substrate leads to a large continuous contact zone between the particles and the substrate and thus to a durable bonding [8]. Kliemann et al used 3-50 µm TiO 2 agglomerates formed from 5 to 15 nm of primary particles for the continuous coating of steel substrate.…”

“…They also tested the bond strength of the coating by ultrasonic cleaning with a maximum intensity of 40.8 W/cm 2 . No local changes in the number, positions, and volumes of the particles could be observed after the cleaning cycle, indicating that the bonding of all the TiO 2 particles to the substrate resists cleaning up to a maximum intensity of 40.8 W/cm 2 in the ultrasonic bath [8]. Kliemann et al used 3-50 µm TiO 2 agglomerates formed from 5 to 15 nm of primary particles for continuous coating of steel, Cu, Ti, and AlMg 3 substrates.…”

Deposition of Titanium Dioxide Coating by the Cold-Spray Process on Annealed Stainless Steel Substrate

The surface of most metals is covered with thin native oxide films. It has generally been believed that to achieve bonding, the oxide covering the surface of metallic particles or metal substrates must be broken and removed by adiabatic shear instability (ASI), whether induced at the particle–substrate interface or at the particle–particle interface. The aim of the present research is to investigate the correlation between the remaining oxide amorphous layer and substrate-deformation with the adhesion strength of cold-sprayed TiO2 coatings towards the bonding mechanism involved. Relevant experiments were executed using stainless steel (SUS 304), subjected to various annealing temperatures and cold-sprayed with TiO2 powder. The results indicate an increasing trend of coating adhesion strength with increasing annealed substrate temperature. The influence of substrate plastic deformation and atomic intermixing at the remaining amorphous oxide layer is discussed as the factors contributing to the increasing adhesion strength of cold-sprayed TiO2 coatings.

“…This could create conditions for stopping the process of destruction of the refractory under conditions of cyclicality for its operation. One of the methods of such a change in the structure of the surface layer of a refractory element is the method of cold gas-dynamic spraying [43]. Spraying can be carried out in several layers, with different properties (Fig.…”
