The basic scientific and technological concept of the project is to use agglomerated nanophased powders to be transferred onto a substrate in the form a coating with very little or none change of crystal structure. This will allow to obtain nano-structured coatings with a crystal size very close to the powder one. The concept will be extended to an important breakthrough concept that is the Supersonic deposition of nanostructured surfaces using multifunctional reactive aggregated nanopowders for coating deposition: the residual chemical energy stored inside the material (uncompleted chemical reactions) can be developed during the deposition to assist deformation effects and contributing to bond together particles onto the substrate via creep/liquid phase sintering mechanisms. Many different systems will be explored pertaining to the aeronautical, mechanical and biomedical fields. The main S/T objectives of the project are: Materials design of based on performance requirements; Development of agglomerated (typically 20-50 microns size) nanophased powder classes (crystal sizes 10-20 nm) suitable for deposition using cold spraying containing either solid lubricants and/or residual chemical enthalpy in proper metal matrix; Cold spraying process development for the reactive deposition (wide range of adds in temperature), and self lubricating nanostructured coatings (synthesis of new nanocomposite materials); Development of three classes of nanostructured coatings for very relevant tribological applications (with self lubricating properties, abrasion and fretting resistance, biocompatibility) which suffer from a complete lack of solutions in the fields of bearings, machines parts and medical devices; The above objectives relates perfectly to the call content since it is intended to develop: novel nanostructured coatings; improved wear behaviour; chemical inertness; new generation of solid lubricants and tribological materials

The objective of the proposed research is to develop improved functionality and new coating applications for aluminium anodisation processes in surface engineering. Project will advance recent innovations towards preparation of ordered nanoporous, nanostructured materials using anodisation methods and applying them to develop commercially relevant novel materials and address the market potential for these improved materials. The nanostructuring process is the growth, during the anodising process, of nanoporous films consisting of well-ordered pores of Anodic Al Oxide in hexagonally close-packed distribution with large aspect ratio. The concept of self-assembly is not yet implemented in actual anodising Al processes due to a number of bottle-necks; project aims at developing pilot line equipment and methodologies enabling to overcome them. The objective is to solve actual market needs by achieving the single stage treatment and industrial evaluation of nanostructured aluminium alloys. The overall research methodology of the Nanocoat project will follow a progression from detailed laboratory studies through scale-up to applications testing on industrial aluminium grades under industrial relevant conditions, to evaluate their structural and functional characteristics, the reproducibility of the process, and to deliver to end-users suitable test structures as predemonstrators. It is expected that on controlling the formation of the anodised nano-size cell structures on aluminium it will be possible to achieve novel performance in terms of adherence, wettability, corrosion and wear, and adsorption/absorption properties. The scope of applications is very large in the field of surface engineering. The specific anodising markets to be addressed during the project are concerned with improved functionality and new coatings for traditional anodisation processes. In addition, new markets will be assessed, which are based on the enhanced performance of these coatings.

The total annual estimated direct cost of corrosion, not including wear damage, in the worlds is estimated at about 3.1% of the worlds Gross Domestic Product (GDP). Protective coatings serve to prevent wear and corrosion and thus reduce the total loss from corrosion and wear. Hard chromium plating is one of the most widely used techniques for production of such coatings. However, hard chromium faces many problems: EU restrictions due to use hexavalent chromium, health issues for the plating industry personnel due to cancers events, functional defects of the coatings and low current efficiency. Thus, there is an urgent need to substitute chrome plating with an alternative one that could provide the same or even enhanced benefits that chrome has, without causing the above problems. The target of the project is to eliminate the use of hard chromium plating in European electroplating industry by delivering a suitable alternative, which will be the nano structured Ni-P and Ni-P composite coatings (with SiC or WC as reinforcing nanoparticles). The successful outcome of the HardAlt project will lead to the restriction or even elimination of the use of hexavalent chromium in electrodeposition industry and will not be subjected in EU legislations. As HardAlt coatings will present equal or even enhanced functional properties compared to hard chrome, they will be adopted by the metal working industry in applications where wear and corrosion resistance is of crucial importance. Significant benefit will be the customization of the HardAlt coatings in the need of each application using the same bath leading to raw materials saving and minimization of wastes from electroplating industry.

Wear and corrosion of materials causes losses of 3-4% of GDP in developed countries and billions of Euros are spent annually on capital replacement and control methods for wear and corrosion infrastructure. As a result many important industries are dependent on surface engineering of protective coatings, making it one of the main critical technologies underpinning the competitiveness of EU industry. There are 2 main techniques that dominate the protective coatings sector: hard chromium (HC) plating and thermal spray (TS). However, HC plating faces a series of issues with most important the extremely negative health and environmental impact leading to the EC restriction of this method for using Cr\6 by the end of 2017. Similarly, recent toxicity studies concerning Co-WC cermet applied by TP have revealed that Co-WC particles are toxic in a dose/time-dependent manner. Consequently, there is the necessity of finding new, less hazardous methods and materials exhibiting the same or better performance compared to existing ones. The PROCETS project will took advantage of the use of nano-particles for production of composite coatings with superior properties compared to those of HC produced by electroplating or to Co-WC produced by TS. These novel nano-particles will be incorporated into existing production lines after appropriate modifications. The new procedures will be easily transferred by minor adaption to the present electroplating and TS facilities, and will combine flexibility and mass customization abilities, restrict environmental and health hazards and finally be available at acceptable cost. Thus, PROCETS main target is to deliver protective coatings covering a wide range of applications such as automotive, aerospace, metal-working, oil and gas and cutting tools industries via thermal spray and electroplating methods by utilizing more environmental friendly materials, compared to the currently used.
