TENSION AND FATIGUE BEHAVIOR OF A PVD TIN-COATED MATERIAL

Experiments were carried out, utilizing an axial tension-compression t esting machine, to assess the tension and fatigue performance of a TiN -coated material, as compared with the uncoated material. The TiN film s of three different thicknesses, namely 3, 5 and 7 mu m, were used. T he results are described as follows: In the tensile tests, the tensile behavior of the coated and uncoated materials was similar, except for the lower fracture strain of the coated materials. In the fatigue tes ts, the application of TiN films was positive; the resulting enhanceme nt in the endurance limit was by 20-40 MPa. (C) 1998 Elsevier Science S.A.
