Corrosion and Wear Materials Solutions

In this episode, Robert Freed, Ph.D., FASM, Associate Director at the Materials Technology Institute, joins co-hosts Heather Allain and Marc Cook for a practical, materials-focused discussion on corrosion and wear. Robert helps clarify the differences between abrasion, adhesive wear, erosion, and cavitation, and explains how these damage mechanisms commonly show up in industrial equipment such as extruders and other high-wear components. The conversation explores key variables that influence wear performance, how wear can accelerate corrosion, and why factors like particle size matter. Robert also walks through methods for evaluating and ranking materials, including relevant ASTM wear tests, metals lab analysis, and the pros and cons of different overlay solutions—such as laser cladding, thermal spray, and weld overlay—as well as non-metallic options. The episode closes with insight into MTI-led research projects and practical considerations for selecting materials and processes to manage wear in demanding operating environments.
