In the field of surface engineering, the high velocity thermal spray technologies are coating deposition processes characterised by the implementation of feedstock materials, which are typically in form of powder and accelerated to high #KineticEnergies as differentiating attribute.

At TECNALIA, we have been working in this field since many years, with focus on two intrinsically different technologies which resulted in the development of proprietary processes and patents. 
On the one hand we have been working on the development of processes based on high frequency cyclic explosions, known as high frequency pulse detonation or HFPDneo. On the other hand, we have developed processes based on the expansion of supersonic gas streams from a high-pressure combustion chamber, which is typically known as the HVOAF technology.

Both are supersonic processes, which are able to generate the required impulse and velocity for accelerating the feedstock powder particles to such high kinetic conditions. 

More recently, we managed to integrate both thermal spray systems within one unique control unite, with the intention of operating each of the system indistinguishable under a flexible environment. This integrated thermal spray system gives us the possibility of generating high performance high velocity coatings for a wide range of industrial applications, with the maximal flexibility in view of the achievable material specifications or requirements, or even customisation potential according to the needs of our clients.    

In general, such high velocity coatings are characterized by their extreme high density, compactness, adherence and intrinsic properties, but above all by their outstanding functional  performances, which represent a benchmark for the thermal spray market and promote their implementation in nearly all industrial sectors we could consider as relevant.  

In all, we can say that at TECNALIA we try to approach all key aspects of surface engineering, all problems related to the development of such dedicated surface solutions from a holistic point of view, always trying to further develop the coating technology in parallel to the development of the related processes, equipments, application procedures, materials and final prototypes. In this way we attempt to cover the whole value chain and offer a global service to the local industry.
