“…The influence of surface morphology on the deposition efficiency has been highlighted also for ceramic substrates. Kromer et al employed laser surface texturing to create specific surface topography enabling the mechanical anchoring of the particles [65]. Nevertheless, different trends were observed depending on the sprayed powders.…”

Surface treatments on polymer-based materials are frequently used to enhance mechanical and physical properties. Cold spray is a metallisation technique that provides a viable solution to overcome the main drawbacks of conventional thermal spray processing techniques related to surface degradation at high temperatures. This review provides a critical overview on the metallisation of polymers and polymer matrix composites using cold spray. It offers an informative read on different approaches, bonding mechanisms, spraying procedures and parameters that influence the deposition efficiency, and the features of the coating. The future scope section broadly highlights potentially relevant areas for further developments using the method for metallising polymer-based substrates.

“…The use of pulsed laser beams to treat the surface of the ceramic substrate provides specific surface modification, thereby affecting the deposition efficiency and bonding strength of the sprayed particles. Kromer et al [75] used laser surface texturing technology to perform surface treatment on alumina ceramic substrates and silicon carbide ceramic substrates, then use cold spray technology to spray aluminum and copper on the surface of the alumina substrate, and spray titanium on the surface of silicon carbide. By changing the surface morphology of the ceramic substrate, a mechanical anchor is formed between the coating and the substrate.…”

“…Before CS, laser surface deformation technique was used by Kromer et al to pretreat the rough surface of SiC and Al 2 O 3 ceramics, the technique promoted mechanical anchoring between metals and ceramics. With the increase of surface roughness, the bonding force between coating and substrate increased from 7 to 20 MPa [27]. In addition, King et al [28] reported that the infiltrated aluminium enters into the opening on the smooth PZT substrate, resulting in increases in mechanical interlocks knots.…”

Since invented in 1980s, cold spraying (CS) has received numerous attentions recently because of its low heat input and high efficiency. Severe plastic deformation induced by high-velocity impaction makes the particles with temperature below the melting point deposited on the substrate. Theoretically, the coating obtained by CS is dense and free of oxidation, so excellent thermal and electrical conductivity can be obtained, which is ideal for ceramic metallisation (CM). Many studies have been done on the CS CM to study the coating structures, bonding mechanism and performances. Mechanical occlusion is considered to be the main bonding type at the interface, local melting plays a small role in the bonding, but local melting improves the bonding strength significantly. However, the specific bonding mechanism of CS CM is still unclear, especially in some metal/ceramic systems with bonding strength greater than 10 MPa, the bonding mechanisms need to be further studied. CS is also difficult to metallise some ceramics, which requires complicated design. Thus, aiming to improve the reliability and the extent of the application of CS CM, a thorough review should be made. In the present paper, the bonding mechanisms of CS metal coating on ceramic proposed by previous researches were summarised to help the researchers a better and quicker understanding for the CS CM. The factors influencing the properties were introduced. The author also made an outlook for the future development of CS in CM.

“…The thermally sprayed coating that is adhered to the surface by a mechanical interlocking mechanism can be classi ed into ve typesembedding, anchoring, holding-on, spreading, and a mixture of several styles [14]. Depending on the material, both mechanical and physicochemical bonds can exist, and the bonding mechanism is in uenced by particle-substrate contact time, contact temperature, and contact area upon impact [15]. It should also be noted that the adhesion strength is not only dependent on the contact area ratio and the density of the features but also varies with the microtexture shape and pattern [14,16].…”

Surface microtexturing improves coating adhesion strength due to increased surface area and mechanical interlocking. Grit blasting and laser processing are two common methods used for surface microtexturing. Laser microtexturing offers distinct advantages over grit-blasting as it improves interface quality, provides a grit-particle-free surface, optimized processing time, and greater control over the surface roughness. This paper reports a full area method of laser microtexturing of Al 7075 alloy using a nanosecond pulsed laser to generate a large increase in surface area. This method involves a laser-induced thermo-mechanical process where tightly packed pillar-like surface features were formed due to the surface melting and re-solidi cation of materials combined with some ablation. The morphology of the microtexture was controlled by varying the laser processing parameters. Thereafter, the laser microtextured surface was coated with metallic coatings using thermal spray. Our method is superior to the currently used laser ablation-based microtexturing method. The surface morphology, composition, and adhesion strength results are presented. The tensile adhesive strength of the thermally sprayed metallic CoNiCrAlY coating was measured, and an improvement of over 17% in the coating adhesion strength was observed for a 5 µm deep microtexture compared to that of grit-blasted samples. This is the highest reported adhesion strength for thermally sprayed bond coating.
