【 摘 要 】

In this paper, beside the documentation regarding the many laboratory tests of X20Cr13 steel, the cavitation erosion, dry sliding wear, hardness respectively corrosion of this martensitic stainless steel was investigate. As cavitation erosion aspects, the authors present some preview results and continue to investigate the cavitation erosion resistance of X20Cr13 steel for an extended duration of 900 minutes of the cavitational attack, duration divided into 30 periods of 30 minutes. All this research through the stationary specimen method was done by using a cavitation stand and the obtained results were presented through cumulative mass loss and cavitation erosion rate versus time curves. As dry sliding wear aspects, the research was done with a CSM Tribometer through the pin-on-disk method and the obtained results were presented by means of the coefficient of friction and the wear rate. As hardness aspects, the measurement was made through the Vickers method using a Zwick/Roell microhardness tester. Finally, as corrosion aspects the research was done with a three-electrode cell using potentiodynamic polarization method and the obtained results were presented as corrosion curve in a logarithmic form.
