FORM ERROR AND HARDNESS PERFORMANCE OF ROCKWELL DIAMOND INDENTERS

J. Song, S. Low, L. Ma

Abstract

The influences of form errors on hardness performance of Rockwell diamond indenter are discussed. Experimental results are introduced. The Finite Element Analysis (FEA) method is used to simulate the hardness measurement process. The effect of tip radii and cone angles on hardness performance is obtained from our FEA model. It is suggested that FEA could be used to establish a relationship between the microform geometry and the hardness performance of Rockwell indenters, and to predict offsets in hardness readings based on the geometry parameters of the indenter, the testing cycle and the mechanical properties of the testing material.
