Important results from the project
We managed to do life cycle analyses on the two current processes for coating carbide inserts with TiN. These showed where in the process the greatest environmental impact comes from. We were also able to show how much more sustainable the process became if you use a Swedish energy mix compared to an Indian one, of great interest as factories are located both in Sweden and in India. Based on our LCA results, we developed a new reactor concept for more sustainable CVD.
Expected long term effects
The results show how to do LCA for CVD of hard coatings and how these can show which parts of the process should be focused on to increase sustainability. Our results can probably lead to a standard for Seco Tools and Sandvik Coromant on how they should work with sustainability in their CVD processes. We may also have laid the foundation for a new reactor concept for more sustainable CVD.
Approach and implementation
The project group has had regular meetings - usually via Teams, but a few times everyone has gathered in Linköping. During the meetings, results have been discussed and new ideas have been brainstormed. One person in the project group is an expert in LCA and has led that work with input data from Seco Tools and Sandvik Coromant. One person in the project group is an expert in CFD modeling and has led the work of testing design ideas for the new reactor concept.
