Abstract

This paper describes a comparison carried out among three measuring systems used to determine the Brinell indentation diameters. One of them is a high precision profilometer, which is a contact method. The other one is a non-contact method that works by image analysis and it is the current system applied at INMETRO's hardness laboratory. The other, that is also a non-contact method, was the one developed at INMETRO's laboratories and it is a system that works with image processing by edge enhancement.
