Porous Copper With Capillary Performance and Gas Permeability Prepared by Two-Step Foaming Method

다국어 초록 (Multilingual Abstract)

Porous copper have been prepared by two-step foaming method using 18%-72 wt% of C18H36O2 for the first-step foaming and 1.5 wt% of C7H10N2O2S for the second-step foaming. The effects of C18H36O2 contents and sintering time on pore structure, capillary performance and gas permeability were studied. The results show that porosity, pumping rate and gas permeability increase with the increase of C18H36O2 contents but decrease with the increase of sintering time. Porous copper with high pumping rate and gas permeability has potential as the support for mass and heat transfer in heat pipe.
