Projektinitiativ #89: Surface Wear Improvement of Tool wear through Supersonic Air Fuel Thermally-sprayed Hard Metals

Friction and wear requirements in wood machining systems are dictated by lifetime limiting problems. Development of novel coating materials for improving the wear and tribological properties of standard WC tools are crucial for ensuring efficient operation and productivity.

Mats Ekevad presents the initiative during the 2017 conference

By applying onto this tools novel combination of Ceramic-reinforced Metal Matrix Composites (CMMCs) with the latest development of Supersonic Air-Fuel spraying process, unique tailored coating microstructures can be achieved combining high adhesion strength with high wear resistance and toughness, which are key-features requirements to combat extreme abrasiveness of wooden products. The overall project goal is therefore to motivate and strengthen the competitiveness and attractiveness of Swedish industries through the development of a new generation of cost-effective Hard Metal thermally-sprayed coatings for wood machining systems. The focus is on gaining fundamental understandings of the correlations between coating microstructure, wear mechanisms and performances in extreme operating conditions, which will lay foundation for (i) improving the tool wear life time, (ii) reducing expensive maintenance cost and production stops, and (iii) generating novel and transferable knowledge toward industrialization.
