abstract
The aim of the proposed project is to extend the property profiles of functionally optimized ternary PVD hard nitride coatings to include the function of effective corrosion protection. The concept of alloying Mg-Gd to TiN developed by the applicant research institution and the knowledge achieved about the influencing factors for ensuring wear and corrosion protection are to be transferred to typical ternary coating systems (e.g. TiAlN, CrAlN, TiCN) in this project in order to make these coatings suitable for use under corrosive conditions.
The results targeted in the project hold the following benefits for kmU:
1. opening up new industrial fields of application for corrosion-optimized PVD coatings under simultaneous corrosive and tribological stress.
2. improvement of environmental and health protection through the possibility of substituting corrosion-optimized ternary PVD hard nitride coatings for the electroplated coatings or electroless nickel previously used in corrosive environments.
3. economic advantages, since corrosion-optimized ternary PVD hard nitride coatings can achieve a higher added value compared to conventional PVD coating systems at similar coating costs due to the improved properties.
4. increasing sustainability, optimal utilization of shifts and reduced maintenance costs through “predictive maintenance” concepts.
Coating equipment manufacturers, coating companies, and users from virtually all manufacturing industries are often classified as SMEs.
With the targeted project results, new business areas and applications can be opened up through the use of corrosion-optimized ternary PVD hard nitride coatings by removing existing obstacles or safety concerns in the use of PVD coatings for components subject to corrosive stress.
