 Abstract
This paper contains some experimental results about erosion wear behavior of materials types AISI 304 and AISI316 gas and plasma nitrated. Thermochemical treatments parameters are presented, the metallographic structures obtained have been investigated, the hardness and thickness of stratums have been determined, and at wear tests developed in formation water have been performed, taking into account the influence above wear of impingement angles.

 Rezumat
Lucrarea conţine unele rezultate experimentale privind comportarea la uzare erozivă a materialelor de tip AISI 304 şi AISI 316 nitrurate in gaze şi nitrurate īn plasmă. Sunt prezentate tratamentele termochimice şi au fost cercetate structurile metalografice obţinute, s-au determinat duritatea şi grosimea stratului nitrurat şi s-au efectuat teste de uzare īn apă de zăcămānt cu o concentraţie de nisip de 10g/l la unghiuri de impact diferite.
