Description

Diamalloy™ 4006 is a nickel-based superalloy powder containing a substantial amount of glassy phases in the sprayed coatings that impart a combination of high wear and corrosion resistance. While many thermal spray materials produce coatings that protect metallic substrates from wear or corrosion at higher temperatures, most do not excel at both. Diamalloy 4006 is unique in that respect, fulfilling a significant need for several applications.
