Critical Raw Materials in Thermal Spray Applications: A Supply Chain Perspective

Critical raw materials (CRMs) are essential components of many thermal spray applications, particularly those for wear protection, thermal barriers, and environmental barriers. However, their supply chains are increasingly vulnerable to disruptions due to geopolitical factors, resource scarcity, and growing demand driven by decarbonization efforts.

This presentation will delve into the current state of CRM supply chains and their implications for thermal spray applications. EU’s Critical Raw Materials Act and the US Secretary of Energy‘s Final Critical Materials List will be examined focusing on metals and rare-earth oxides, which are crucial for various thermal spray processes. The study will assess the risks for supply chain disruptions in short and mid-term. Furthermore, strategies for mitigating risks associated with CRM dependency will be discussed, including promoting sustainability and circularity for CRM products, diversifying sourcing, and developing alternative materials or processes. The presentation will explore the roles of different stakeholders, including application engineers, purchasing departments, and material developers, in addressing the challenges posed by CRM supply chain vulnerabilities.

With a better understanding of the current landscape and exploring potential solutions, we can contribute to the development of more resilient and sustainable thermal spray applications that can meet the demands of a decarbonizing world.
