Method of determining the essential geometric characteristics of the metal foam structure

Abstract

The paper deals with the description of method, proposed by authors, that determining the essential geometric characteristics of the metal foam structure with using of the analytical imaging software. Method use economically available technical apparatus and software with emphasis on maximum consideration of the measurement uncertainty by Kline-McClintock method. The image analysis used three kinds of metal foams with a pore density of 10 to 40 pores per inch. The most important parameter - the size of a metal foam cell ranged from 1,165 mm (for 40 PPI) through a 2,262 mm (for 20 PPI) to 5,660 mm (for 10 PPI).
