Perforability - a correct term similar to Russian "перфорированность", meaning "relative area of a surface occupied by pores"

Question

I'm looking for the correct translation of the Russian term "перфорированность" and find the "perforability" but don't know, is it correct?

From the physical point of view "perforability" means the relative area of a surface occupied by pores.

This term can be used in (scientific) papers.

For example, the sentense

To calculate the relative area of perforations (pores) on the surface of crystal slices, we use the following method ...

can be changed to a new one

To calculate the perforability of crystal slices, we use the following method ...

There is a close term "porosity" that means the relative volume of a solid occupied by pores. But I need a term for the surface area.

Can perforability be used for this?

Answer 1

The OP requests a term for "the relative area of a surface occupied by pores."

porosity / surface porosity

The definition of porosity is

The ratio of the volume of interstices of a material to the volume of its mass m-w

Porosity characterizes the volumetric aspect of the pore system. Jürgen Schön; Physical Properties of Rocks

However, porosity appears to be used for surfaces as well.

A modified theory of the later, ..., applies to non-porous surfaces. Standard curves are more useful, especially if one is interested in porosity, although most depend upon calibration by some other interpretation, usually the BET. (p.56)

ONC® is a process that takes advantage of surface porosity observed in most compound layers after nitriding. It is a simple concept but the process is not easy in that the amount of porosity generated during the nitriding stage must be properly controlled. ASM, and N. Dahotre; Heat Treating and Surface Engineering (2003)

The original Cassie equation did not include a term for porosity, but it was expanded to include surface porosity... Felix N. Büchi et al.; Polymer Electrolyte Fuel Cell Durability (2009)

In general, the higher the porosity, the higher the permeation flux. Depending on the fabricate technique, its pore distribution can be inhomogeneous, resulting in a surface porosity that differs from the bulk porosity. J. Hu et al.; Handbook of Fibrous Materials, Vol. 1

Answer 2

I'm assuming this is a 2D or pseudo 2D situation, where the areas in question are projections on a plane. That's pretty much the only way that a pore has an area that is different from the solid surface area.

Relative measurements are rendered as coefficients in technical English, or sometimes as specific X. There doesn't appear to be an established single term for this. And there are several seemingly appropriate terms that are already claimed for different measurements and that have test standards and definitions.

After surveying some technical documents on filters, I suggest "relative pore surface coverage" as used in the abstract which follows - https://cyberleninka.org/article/n/1416663

Answer 3

From the context and your helpful example, I suggest that permeability, which is a term commonly understood in physics, engineering and geology, might satisfy your need.

Merriam Webster

permeability:

the quality or state of being permeable

Merriam Webster

permeable:

capable of being permeated : Penetrable especially : having pores or openings that permit liquids or gases to pass through

// permeable membrane"

The concept applies to three-dimensional structures but, as the Merriam Webster example of membrane suggests, it also applies to a thin structure or surface such as your thin crystal slices.
