Hard Coat


Acronym: HardCoat

Surface HARDening and highly wear-resistant nanocomposite COATtings for woodworking tools

Project: COFUND-M-ERANET-3-HardCoat-1, no. 312/2022

Project Period: 27.06.2022-31.12.2024

Financial supported by Romanian National Authority for Scientific Research (CNCS-UEFISCDI) by PN IIII – European and International Cooperation – Horizon 2020


In cutting tools industry, economic considerations play an important role, thus the surface modification technology is to be applied to ensure the required functional properties while using as cheap as possible materials for the bare element. This element, being required to generally, results in lower performance. A wide selection of currently available types of composite coatings and their deposition technology is the result of an increasing demand for modern methods of surface modification and protection for tools, machine parts and other components.
Through this project the development in surface modification of cutting tools used in wood industry as well as the optimization of methodologies for investigation of mechanical, physico-chemical, surface and interfacial properties like wear and corrosion performance of this materials is intended. In order to understand the complex interactions in the interface between substrate and coatings as well as the functional surface, the use of state-of-the-art equipment for extensive in-situ studies is necessary. General statements on increasing the service life and efficiency in use require the development of realistic test conditions for the novel materials. The complex requirements for screening tests for validation purposes enable information of the highest quality, which directly benefits the regional, European and global sector of wood device technology. One particular aim is to test the prepared prototypes in industrially operational environment (TRL6) – tasks which will be performed by the industrial partner in woodworking industry.

Work plan:

WP1: Testing of the cutting tools used in wood industry coated by thin films by consotium partners (monolayer structures)

WP2: Testing of the cutting tools used in wood industry coated by thin films by consotium partners (multilayer structures)

WP3: Testing of the cutting tools used in wood industry coated by thin films by consotium partners (gradient structures)
