In this study, CrN/CrAlN multilayer coating with different periods (Ʌ = 1, 2, 3, 4) were deposited on
stainless steel (90CrMoV8) and silicon Si (100) samples by DC magnetron sputtering. The results obtained
exhibited that the increasing of the number of periods considerably improves the properties of multilayer
coatings. All CrN/CrAlN multilayer coatings have a dense columnar microstructure, and the surface
morphology showed a pyramidal shape with nanopores. The coating hardness and Young’s modulus of the
CrN/CrAlNmultilayer coating increases with the increase of bilayers number and reach 40 and 392 GPa
respectively. Friction coefficient in seawater environment was calculated and it show that the increase in
bilayer number decreases friction contact and reduce the friction coefficient. Also, wear resistance
improves with increasing interfaces and increasing hardness.
