Abstract
Macrostructure of nickel foam with porosity of 20, 30, 45, and 60 ppi is investigated by X-ray tomography at voltage U = 300 kV, current I = 300 mA, and exposure time texp = 354 ms is investigated; the number of frames was 2500. It is established that actual parameters of pores deviate from theoretical ones. It is shown that the higher porosity is, the more uniform the pore-size distribution is. The X-ray tomography makes it possible to evaluate such characteristic as the thickness of the wall between the pores, which was not taken into account previously. It is revealed that the uniformity of the wall thickness with respect to sizes decreases as the sample porosity increases. These results make it possible to recommend the X-ray tomography as the method for the investigation and monitoring the foam materials and powders in various sintered materials, and the acquired data can be used to create actual three-dimensional models.
