This type of hardness test is also performed by applying controlled force for a specific amount of time to an indenter, which in this case is a square-based diamond pyramid. As a result, copper has been used by man longer than perhaps any other metal. You may also apply an extra amount to the total payment to accelerate debt payoff even further. Vickers hardness values are reported in the form: value HV force, for example, 650 HV 100 corresponds to a Vickers hardness of 600 measured with a 100 gf force. On the Vickers hardness scale, parts coated with Zn-Ni reach 450, compared to less than 150 for zinc-coated parts. The hardness number is based on the applied force divided by the surface area of the indent itself, giving hardness units in kgf/mm². or mm, and D = specified outside diameter, in. HRC, HRB, etc.) Fabricated by machining, roll threading and knurling. The equation for irreversible cyclic process may be written as: + I= 0 I = Amount of irreversibility of a cyclic process.
