Wood is a readily available heterogeneous material with plenty of varieties used in furniture, packing, building constructions, beam flashings, flooring, and many other applications. Considering the importance of forest industry in Canada (205,000 jobs and $33B in exports, 2019 data) wood cutting occupies a key role in this industry. Specifically, according to the government of Canada's 2020 report on the 'state of Canada's forests' more than 158 million cubic meters of industrial round wood has been harvested in 2018 in Canada. One of the major challenges faced by industry is the rapid deterioration of the cutting tool, which significantly reduces the surface quality of the cut wood, increases wood waste, and leads to significant increase of the number of cut trees for the same amount of processed wood. Therefore, the use of high-performance long-lasting tools will have significant environmental (cutting less trees for the same total production) and economic (tool replacement, low quality wood production, etc.) impacts for Canada. However, producing high-performance long-lasting cutting tools is a multi-faceted complex scientific and technological problem. The goal of the proposed 4-year project is to better understand the fundamental interactions between alloy composition, heat treatment parameters, surface preparation, and coating characteristics on the performance of wood cutting tools with the view to develop the next generation of high-performance wood cutting tools.

木材是一种容易获得的异质材料，具有大量在家具，包装，建筑物结构，横梁闪光灯，地板和许多其他应用中使用的品种。考虑到森林行业在加拿大的重要性（205,000个工作岗位和33B美元的出口，2019年数据）在该行业中造成了关键作用。 具体而言，根据加拿大政府2020年关于“加拿大森林”的报告，该报告已于2018年在加拿大收获了超过1.58亿立方米的工业圆形木材。行业面临的主要挑战之一是切割工具的快速恶化，这大大降低了切割木材的表面质量，增加木材废物，并导致相同量的木材的切割树木数量显着增加。因此，使用高性能的长期工具将具有明显的环境（相同总生产的树木较少）和经济（工具更换，低品质的木材生产等）对加拿大的影响。但是，产生高性能的长期切割工具是一个多方面的复杂科学和技术问题。拟议的4年项目的目标是更好地了解合金组成，热处理参数，表面制备和涂料特征对木材切割工具的性能之间的基本相互作用，以期开发下一代高性能木材切割工具。
