“…Different nozzle materials have different effects on the coating deposition efficiency, which may depend on the thermal diffusivity of the nozzle material and the interaction of powder particles with the nozzle inner wall during cold spray. Nozzles with higher thermal conductivity can reduce critical velocities of the powder material, resulting in higher deposition efficiencies (Ref 48 , 49 ). The effect of nozzle material on cold spray performance and applicable materials needs further investigation in the future.…”

In recent years, cold spray technology has attracted more and more attentions. After more than 30 years of rapid development, research focus of cold spray technology is gradually shifting from fundamental and theoretical studies to application developments, some of which have been industrialized and mass-produced. In this paper, the characteristics of cold spray technology, cold spray materials perspectives and cold spray system developments were briefly introduced. Besides, the recent developments of cold spray applications in different fields including aerospace, biomedical, energy, electronics, semiconductor fields were discussed. Although cold spray technology is in the early stages of implementation, it has demonstrated a great potential to reduce costs and improve performance. World-wide awareness of ongoing and planned cold spray programs is critical to expand its applications and benefits.

Compared to thermal spraying, the cold spray (CS) process features virtually oxide-free coatings without thermal defects and residual stress, and it is suitable for processing Ti and its alloys. This review focuses on microstructure control and current properties of CSed Ti and its alloys coating to elucidate and expand their applications. A critical overview of the main processing parameters governing the microstructure of the coating has been presented and discussed, combined with some useful results from the studies reported by various research groups. The porosity and mechanical properties of CSed Ti and its alloy coatings have been summarised. A synopsis of the measurement techniques of each property has also been presented herein.

“…Limited deformation of substrate underneath well deformed and flattened particle as presented in Figs. 2 (c) and (f) suggests that impact with the nozzle wall and with other particles prior to hitting the substrate might have played an important role in the particles deformation [49].…”

Impact morphology and deformation of single splats were modelled through FEM simulations using PTW plasticity model to account for large strain rates.Annealing experiments and consequently formed interfacial intermetallics layer were investigated.Correlation of interfacial intermetallics pattern with highly strained interface area, predicted by modelling, present a new insight to the extent of particle/substrate metallurgical bonding. Metallurgical bonding of a particle/substrate is more likely to be found at peripheral areas of the interface which extends from there to the base of the particle with increase of kinetic energy of impacting particle.
