Surface engineering is in a permanent evolution to face more and more severe requirements and HSE regulations such as REACH. The functional properties of many materials, components and systems are often based in full or in part on their surface. Each case is specifi c while many technologies can be first considered depending on numerous parameters: substrate material, size, geometry, quantity, targeted functionalities, post-operation… Therefore, it is crucial in many application fi elds to optimize the choice of coating or surface modification to get best performance, process capability and robustness.
Additive Manufacturing is not really a new technology, as this whole story comes from the stereolithography invented by Charles Hull in 1986, and rapid prototyping has been in use for more than 15 years. What is new is the impressive acceleration of the use of AM in an ever-increasing number of industries, at ever faster speeds and with more and more metallic and polymeric materials. It can be said that all sectors are impacted today giving a real revolution.
Today, NDTs are used to ensure the integrity and reliability of products and reduce production costs by maintaining a permanent level of quality of structures and (multi-material) assemblies increasingly multi-material. The acceleration of the innovations generated by information technologies, IoT, IA and nanoelectronics enables the generation of new, more reliable and continuous advanced NDT solutions whose emergence and maturation must be closely monitored.
