Industrial: Powder Metallurgy - Production and Properties

An irregular shaped particle will have a greater surface area than a spherical powder of the same size. Surface roughness and surface connected porosity can increase the specific surface many times more than the area associated only with size and shape factors. The activity of a particle generally increases with increasing surface area.

Shape is also important - spherical particles burn more slowly than high surface area …

What is E-Coat? - ClearClad Coatings, Inc.

The minimum thickness requirement is 12 microns. E-coating is able to deliver this within the range of 12 – 13 microns. Good quality spray paints need to apply 12 – 18 microns to be certain of maintaining a 12 micron minimum. Powder coating cannot deliver much less than 30 microns and will normally work within a 30 – 60 micron range.
