Dec 25, 2009· Fig. 6 shows the erosion of a (Ti,Al)N/TiN multilayer system coating consisting of 15 alternating (Ti,Al)N and TiN layers of equal thickness and a total coating thickness of 20 μm to better demonstrate this effect. When using large silica sand particles the erosion damage looks very different.
Quartz sand, silica sand, anthracite coal, garnet, magnetite, and other materials may be used as filtration media. Silica sand and anthracite are the most commonly used types. When silica is not suitable (e.g., in filters following a hot process softener where the treated water is intended for boiler feed), anthracite is usually used.

In a sense, thermal diffusivity is the measure of thermal inertia. In a substance with high thermal diffusivity, heat moves rapidly through it because the substance conducts heat quickly relative to its volumetric heat capacity or 'thermal bulk'. Thermal diffusivity is often measured with the flash method.
