An Experimental Study Concerning Some Effects Occurring During Skeleton Infiltration with Liquid Metals
A study has been undertaken on the mechanism of infiltration of high-melting metal skeletons (e.g., tungsten) with low-melting metals (e.g., silver). The higher-melting metal skeleton was produced by pressing, or pressing and sintering of adequate metal powder, so as to compare differences in the phenomena which occurred. The influence of grain size and grain-size distribution of the skeleton powder, the skeleton porosity and individual pore dimensions, as well as parameters affecting the wetting process, are discussed. Metallographic, hardness, and other tests were adapted to investigate the infiltration process. Some general rules on infiltration were derived from the experimental data.
