In this paper is a study the influence of the material and heat treatment on the
changes of the fine structure parameters of the superficial layer of triboelements
during the first cycles of rolling contact process. The tests were conducted by using
a four-roller testing machine. The specimens (rollers) were made of case-hardening,
through hardening and high frequency hardening steels. In order to induce different
stress distributions in the superficial layer of the specimen specific treatments were
applied. Using X-ray diffractometry can be appreciated that the durability of rolling
tribosystems can be determined by an optimal relationship between studied
parameters. The observed correlation can be used as a fast method to estimate the
fatigue life of rolling bearing materials.
