چکیده
Multilayered films are a new kind of coating that belong to a more plentiful family of materials labelled as nanostructured materials. These kinds of coatings stand in the frontier of investigation in thin films for structural applications. In the present Ž . work, multilayered coatings with alternated layers of W]Ti] N and Ag were deposited to be used as wear resistant surfaces. The Ž . w association of the high hardness, wear resistance of W]Ti] N layers Proceedings of the Eleventh LAWPSP Symposium, Ž . Ž . x SL1.1-SL1.7, Bombay, India 1998 ; Surf. Coat. Technol., 102 1998 , 50 and the good ductility of the silver ones is the guarantee of obtaining a better mechanical performant coating. However, to reach a satisfactory comprehension of the behaviour of the coatings in service a true understanding of some important properties is needed. For this reason, hardness, Young modulus, internal stresses and adhesion were evaluated, as well as function of the number and thickness of the layers. Q 2000 Elsevier Science B.V.

Delamination of Two-Dimensional Functionally Graded Multilayered Non-Linear Elastic Beam - an Analytical Approach
Delamination fracture of a two-dimensional functionally graded multilayered four-point bending beam that exhibits non-linear behaviour of the material is analyzed. The fracture is studied analytically in terms of the strain energy release rate. The beam under consideration has an arbitrary number of layers. Each layer has individual thickness and material properties. A delamination crack is loc...

In the present work, attempts were made to investigate the reinforcement and treatment effect of GF on morphological and rheological behaviour of GF/epoxy vinyl ester composites. GF was incorporated into epoxy vinyl ester resin by sonication, and mechanical agitation. Rheological and morphological properties were studied as a function of particle treatment and size distributions. The dispersion...
