MEZA, J. M; DEVIA, A  e  VELEZ, J. M. The importance of RID and P Vs h curves on indentation studies of TiN films deposited onto M2 and 304L steels. Rev.fac.ing.univ. Antioquia [online]. 2006, n.37, pp.93-106. ISSN 0120-6230.

A hardness study of TiN films onto M2 and 304L steels applied by PAPVD was conducted in this work. Instrumented indentation and hardness equipments allow to asses this property. Crack patterns produced during these tests were correlated with this information. In addition, from the P-h/t (Load-displacement/film’s thickness) plots, called Relative Indenter Displacement plots, and P-h plots important information was obtained about the capacity of these systems for supporting load. Both graphics showed to be of great importance for understanding the mechanical response of these systems to indentation.
