Ceramic coatings of distinct microstructures, namely TiSiN
and CrN, were deposited on tool steels. The corrosion resistance of the coated steels was
measured. Following nanoindentation, immersion tests were conducted in 70% HNO3 solution for 96
similar to h. Deformed CrN, where deformation occurred through shear sliding of columnar grains,
was insensitive to corrosion attack. In contrast, open cracks formed in the indented TiSiN
coating, serving as pathway for reactive agents to penetrate through the coatings. Finite element
analysis was applied to evaluate the damage tolerance of the coatings and its impact on the
corrosion resistance of the coated steels.
