Porosity may take on several forms from interconnected micro-porosity, folds, and inclusions to macro porosity visible on the part surface. The end result of porosity is the creation of a leak path through the walls of a casting that prevents the part from holding pressure. See more Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some … See more Used in geology, hydrogeology, soil science, and building science, the porosity of a porous medium (such as rock or sediment) describes the … See more Casting porosity is a consequence of one or more of the following: gasification of contaminants at molten-metal temperatures; shrinkage that takes place as molten metal solidifies; and unexpected or uncontrolled changes in temperature or humidity. See more • Void ratio • Petroleum geology • Poromechanics See more In gas-liquid two-phase flow, the void fraction is defined as the fraction of the flow-channel volume that is occupied by the gas phase or, alternatively, as the fraction of the cross-sectional area of the channel that is occupied by the gas phase. Void fraction usually … See more The ratio of holes to solid that the wind "sees". Aerodynamic porosity is less than visual porosity, by an amount that depends on the constriction of holes. See more Several methods can be employed to measure porosity: • Direct methods (determining the bulk volume of the porous sample, and then determining the … See more WebOn the right, the gaps between the closing surface and measured surface is shown as a “void surface,” which represents the void areas where leakage may occur. As with the 2D analysis, changing the radius of the closing filter can be related to changes in conformability and sealing forces.

Cracks in an aluminum head or block, on the other hand, are much more difficult to repair by pinning because aluminum is a softer metal than cast iron so the pins and plugs can’t achieve as much “bite” as they do in an iron casting.

WebMay 1, 2012 · “With other test methods, porosity will show up as a leak because pressure or flow measurement devices will detect a change as gas seeps into the pores in the casting,” McLaren points out. “Helium leak testing detects gas that escapes from the part, so only true leaks are detected, reducing false positives.” Leak Testing Methods
