1. Propriedades magnÃticas e Ãpticas de filmes finos rugosos
In this dissertation we study the influence of susbtrate roughness on the magnetic and optical properties of polycrystalline permalloy (Py) films and the optical properties of thin silver (Ag) films, when deposited on this support. The surface roughness of the glass substrates was generated by chemical attack with high concentration flouridic acid vapor (HF-

2. EFEITO DO TRATAMENTO SUPERFICIAL EM LIMAS DE NITI SUBMETIDOS A CARREGAMENTO EM TORÇÃO / THE EFFECT OF SURFACE ON NITI FILES SUBJECTED TO TORSION LOADING
NiTi Profile® 25/.04 files do not undergo surface polishing treatments after machining, and therefore exhibit local stress concentrators and, consequently, areas of cracking and fractures. The effect of different surface conditions on the torsional strength of endodontic files were evaluated. 18 NiTi Profile® 25/.04 rotary files were examined by scanning e
