The stress and plastic strain distributions around pyramidal indenter in steel 10 has been investigated by exploring the Vickers hardness of carefully prepared median plane sections through indentations. Experimental results showed that, the maximum strain is observed at a certain depth below the indentation surface inside the hydrostatic compression zone. The minimum permissible ratio between the coating thickness and the indentation depth, which excludes the influence of the substrate on the indentations results obtained by Vickers indenter, is substantiated. The shape and dimensions of plastic deformation zones around Vickers indentations were determined. As a result, between the indentation volume and the deformation zone volume established directly proportional relationship.
