In this work, the influence of oxidation during austenitizing heating in air. before quenching, on the fatigue-life of an AISI-D3 steel previously machined by electrodischarge machining, is studied. It has been determined ...

The surface of pure iron sheets have been submitted to spark-planing erosion using kerosene as dielectric under a wide range of machining conditions: discharge duration times between 2 and 3072 μs, and spark currents between ...

Changes in manufacturing processes used in dental components (implant/abutment) may imply different levels of surface roughness. Therefore, the interaction between them results in different contact areas with their respective ...

The aim of this thesis is focused on the evaluation of different micro-mechanical technologies such as: Wire Electro-Discharge Machining/Sandblasting, Abrasive Water Jet and Micro-End Milling, for the fabrication of ...

The process of EDM or EDM (Electrical Discharge Machining) has wide applicability in materials machining situations with high hardness and resistance to abrasion and parts whose complexity makes it difficult to machining ...

A model for prediction of parameters that defined roughness surface [Ra] when this texture is produced by Electro Discharge Texturing [EDT] is presented. The non-linearity, instabilities and expensive experimentation in ...

This thesis tackles the problem of endodontic fi les fractures from two views; In the fi rst instance, alternative materials to the classic Nickel-Titanium alloy such as Titanium-Niobium and Titanium-Molybdenum were ...
