DOIAbstract
TiN coatings 0.5mum thick were deposited by plasma are deposition on 9Cr18 steels. Vickers indentations, depth-sensing indentations and nanoscratches were produced with different tips on a broad range of applied load. Mechanical behavior of hard and brittle thin coatings on soft and ductile metallic substrates was investigated and interpreted. It is demonstrated that depth-sensing indentation and nanoscratch tests can provide more information about the near-surface elastic-plastic deformation, friction and wear properties. Compared with 9Cr18 steels, solid lubricating effects for TiN and organism/TiN coatings are very marked
