Regularities of the capillary transport in porous materials of Ti-alloy(BT6) fibers

摘要

The kinetics of the capillary absorption of ethanol by high-porous (70-75/100) materials of discrete fibers of titanium alloy(samples have had sizes 330 X 20 X (0,4-1,3)mm) was investigated. The initial fibers of 3 mm in length and 20-140 mm in diameter have been received by method of high-speed hardening of melt. The capillary transport against gravity was studied at the pressure of saturated liquid vapor up to its arriving the height of balanced raising. The experimental data of the speed of absorption were analyzed taking into account the characteristics of structure of porous space( the effective porous sizes, the coefficient of porous canal twisting and the value of free surfaces).
