FeedbackHardness - an overview ScienceDirect Topics

Hardness is a measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied (Fig. 8.41).Macroscopic hardness is generally characterized by strong intermolecular bonds, but the behavior of solid materials under force is complex; therefore, there are different measurements of hardness scratch hardness, indentation hardness, and rebound hardness. What is the hardness of the surface of components?What is the hardness of the surface of components?The hardness of the surface of components is an important property affecting their tribological performance. For components with non conformal contacts such as rolling bearings and gears, the hardness, and the corresponding compressive strength, of the surface material must be above a critical value.Hardness What is the maximum number of readings for Rockwell hardness?What is the maximum number of readings for Rockwell hardness?ASTM recommends reporting readings between zero and 100, although readings up to 120 are permissible. In a Rockwell hardness test, initially a minor load of 10 N is applied and the zero datum position is established.Rockwell Hardness - an overview ScienceDirect Topics

For Rockwell hardness, there are two conditions that are used for polymers. The shore hardness test uses pin-shaped indenters, whereas a Barcol indenter is used in Barcol hardness testing.Rockwell Hardness - an overview ScienceDirect Topics
