The inserted image shows an optical micrograph of the transverse cross‐section of a titanium nitride coating on a commercially pure titanium (CP‐Ti) sample. The titanium nitride coating was deposited by scanning the CP‐Ti specimen multiple times in the presence of a nitrogen plasma sustained by a CO 2 laser and a coaxial flow of nitrogen. The cross section shows TiN dendrites, the heat affected zone and the base metal. Crack formation can be observed in some areas of the coating. Micrograph courtesy of Amar M. Kamat, The Pennsylvania State University.
