 Abstract
This paper aims to make an evidence of the main aspects regarding the deterioration of surfaces affected by contact fatigue. One possible way to reduce the deterioration of contact surfaces can be the option of the geometry of surfaces in contact, this paper containing the justification for using a certain type of test bar.
The trials for the contact fatigue were made using an original device having a test bar made of various materials with the same sizes and with different functioning methods.


 Rezumat
Lucrarea de faţă îşi propune trecerea în revistă a aspectelor principale cu privire la deteriorarea suprafeţelor la oboseala de contact. O posibilitate de reducere a deteriorării suprafeţelor de contact poate fi alegerea geometriei suprafeţelor în contact, în lucrare apărând justificarea folosirii unui anumit tip de epruvetă.
Încercările la oboseala de contact s-au făcut cu un dispozitiv original cu o epruvetă din diferite materiale cu aceleaşi dimensiuni şi cu regimuri diferite de funcţionare.
