a STEM-BF cross section of the as-deposited coating showing columnar grains within the c-AlN/CrN region. The inset shows a SAED pattern taken from the grain marked by the white circle; b HR-TEM image of the c-AlN/CrN multilayers corresponding to the white rectangle in a. Coherency between the layers is evident
