impregnate

[im′preg‚nāt]
(engineering)
To force a liquid substance into the spaces of a porous solid in order to change its properties, as the impregnation of turquoise gems with plastic to improve color and durability, the impregnation of porous tungsten with a molten barium compound to manufacture a dispenser cathode, or the impregnation of wood with creosote to preserve its integrity against water damage.
(medicine)
To fertilize or cause to become pregnant.

The test objective was to determine the vacuum-and-pressure method (with a salt-containing agent) influence on wood strength under normal conditions, and when exposed to high temperatures in the course of impregnation treatment.
A 20% solution of a fire-protection impregnation agent commonly used in Poland was applied for tests.
At the normal temperature (20[degrees]C), the impregnation effects were:
The impregnation with the salt-containing agent by the vacuum-and-pressure method makes a significant effect on wood strength parameters.
Based on the analysis of test results and on literature regarding impregnation issues, a statement may be made that the favourable results of the vacuum-and-pressure impregnation (ie decreased wood inflammability and combustibility) are accompanied by some unfavourable phenomena such as decreased strength and impact strength, and brittleness.
