Hardness testing insight | Struers.com

Cutting and grinding may introduce deformations. These must be removed by polishing down to 6.0, 3.0, or 1.0 μm, depending on the hardness test load. For small loads (less than 300 gf1) the surface needs to be completely free of deformations, and the specimens require oxide or electrolytic polishing to obtain a completely damage-free surface.

Choosing the Right Blast Media for Abrasive Blasting

When a sufficiently hard abrasive particle strikes steel, it deforms the surface into a valley and pushes up peaks. The distance between the top of the peak and the bottom of the valley is known as the depth profile. In the U.S., the depth profile is measured by mils – thouhs of an inch.In the metric system, the micron(one millionth of a meter) is used.
