Important results from the project
HY-GLAS produced the planned results and the primary goal was to evaluate the feasibility of Fe-based bulk metallic glass (BMG), specifically the QT-BMG alloy, as a coating solution using established powder-based deposition techniques was met. Successfull demonstration of HVAF coatings with 100% amorphous structure and considerable wear resistance comparable to commercial coating materials. QT-BMG shows a very promising combination of properties, material cost, and environmental footprint.
Expected long term effects
The project demonstrated the feasibility of QT-BMG as a wear-resistant coating. Successful upscaling would enable substitution of e.g., hard Cr and WC-Co, reduces environmental impact and cost, and opens new application areas. With wear resistance close to Co-based alloys and a footprint similar to stainless steel, QT-BMG supports Nordic industry through Fe-rich chemistries, enhancing circularity and supply resilience.
Approach and implementation
The HY-GLAS project was structured into three work packages: management, experimental proof of concept, and feasibility planning. It demonstrated the viability of QT-BMG coatings through successful trials and stakeholder engagement. Despite minor timing adjustments and change of project manager, the project stayed on track and within budget, resulting in a solid plan for continued development and upscaling for industrial implementation.
