Abstract

Predstavljen je postopek analize geometrijskih značilnosti realnih kovinskih odprtoceličnih pen s pomočjo računalniške tomografije in naknadne obdelave zajetih slik. Opisan je način izgradnje in analize tridimenzionalnega računalniškega modela pene, na katerem je bilo prepoznanih in izmerjenih 5735 robov celic, 2963 oken in 179 celotnih celic. Primerjava z obstoječimi rezultati pokaže, da se kovinske pene močno razlikujejo od teoretičnih ravnovesnih modelov in od raziskav tekočih pen (pena milnice).

Secondary title: Structure of real metal foam
Secondary abstract: A procedure for analysis of geometrical features of real metal open-cell foams using computer tomography and additional image processing is presented. A method for creation and analysis of a three-dimensional computer foam model is described in which 5735 struts, 2963 windows and 179 cells were detected. When compared with existing results the measurements show that the structure of real metal foam significantly differs from the theoretical equilibrium models and research on liquid foams (soap froth).
