Avoiding Porosity in Mining Engineering Castings ChinaSavvy

Porosity sealing, also know as vacuum impregnation, involves the filling of porous substrate to make the part used in mining engineering applications, airtight. Usually applied on powder metallurgy, die cast and permanent mold casted parts, porous sealing takes place in four steps: Under a reduced pressure, the within the pores are expanded.

Porosity - Engineering ToolBox

Porosity is expressed as the volume not occupied by solid material. n = V v / V = 1 - ρ bulk / ρ solid (1) where . n = porosity. V v = void volume (m 3, ft 3) V = total volume (m 3, ft 3) ρ bulk = bulk density (kg/m 3, slugs/ft 3) ρ solid = solid density (kg/m 3, slugs/ft 3)

Porosity - Wikipedia

Feb 14, 2003  Porosity or void fraction is a measure of the void 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 tests measure the "accessible void", the total amount of void space accessible from the surface. There are many ways to test porosity in a substance or part, such as industrial CT scanning. The term porosity
