Coating Characterization
The coating has good resistance to high temperature erosion
and sliding wear. Thermal shock resistance is fair. General
corrosion and high temperature corrosion resistance are very
good. Excellent anti-stick properties. The coating is inert to
molten metals (zinc, aluminum, etc.).
Typical Applications
Sliding wear and erosion at high temperatures, specifically
for work with molten metals (die casting parts, galvanizing
bath parts, sink roll, etc.).
