26-56 CERCETAREA EROZIUNII CAVITAŢIONALE ASUPRA OŢELULUI INOXIDABIL X2CrNiMn22+5+3 TRATAT TERMIC

THE RESEARCH OF EROSION CAVITATION ON STAINLESS STEEL X2CRNIMON22+5+3 HEAT- TREATED
In this paper is presented a comparative analysis between cavitation resistance of stainless steel austenito-feritic and OH12NDL stainless steel (traditional steel). To assess the damage produced by Cecil cavitaţionale implosion over stainless steel duplex X2CrNiMn22 + 5 + 3 tests have been carried out in the laboratory of Cavitation at the University Politehnica Timisoara. The assessment of the data and the interpretation of the characteristic curves of cavitation (loss of mass and speed of erosion) could find that stainless steel X2CrNiMn22 + 5 + 3 heat-treated by quenching followed by tempering the high cavitation resistance exhibited a higher compared with traditional steel OH12NDL.

Keywords: stainless steel, cavitationala erosion, characteristic curves, mass loss, resistance to cavitation
