A three-dimensional topographic reconstruction system of the forge pattern surfaces through laser triangulation has been purposely designed and evaluated. With this work, the results of the topographic study of the forge pattern subjected to ion implantation and/or coated with Ti/TiN layer are being presented. Further, the system permits not only to monitor carefully the wear's performance of the pattern but also find the localization of the points at its highest efforts arising from the forge process as well as any defects caused by the variation of the treatment the piece have been exposed to.
