The Rockwell hardness values are expressed as a combination of hardness number and a scale symbol representing the indenter and the minor and major loads. For example, 64 HRC represents the Rockwell hardness number of 64 on the Rockwell C scale (see Table 1), while 80 HRB represents a Rockwe...

(8) formed in the recesses. A part of the contact surface is harder than the supporting body, where hardness of the part of the contact surface is about 50 Rockwell hardness. The supporting body is coated with hard material. The contact surface is formed at a supporting plate (16). The...
