Slurry erosion resistance of boride-based overlays containing boride crystals oriented perpendicularly to the wearing surface

► Wear resistant Fe-Mo-B-C-Si overlays. ► Specific deposition parameters lead to peculiar microstructure. ► Fe2B crystals aligned mainly perpendicularly to the wearing surface. ► Carbon and molybdenum toughen the steel supporting matrix. ► Outstanding slurry erosion resistance at impact angles of 30° and 90°.
