Nanoindentation studies and modeling of surface layers on austenitic stainless steels by extreme electrochemical treatments

Popis výsledku v původním jazyce

The nanoindentation studies were performed on two austenitic stainless steels, AISI 304L and 316L. The steel samples have undergone two different electrochemical treatments, standard (EP50) and a high-current density electropolishing (EP1000). Firstly, the observations of the steels' surfaces were done with the optic images of the AISI 304L and 316L SS after these two treatments displayed. Presented in the paper results have shown clearly that the high-current density close to 1000 A/dm2 allows for obtaining the passive nanolayers with other mechanical properties than those obtained after a standard electropolishing (EP50). The prediction of these results has been confirmed by the preliminary XPS studies allowing for modeling of the steels' surface layers. The main finding of the study is revealing a new method of electrochemical treatment (EP1000) allowing to obtain the reduced Young's modulus of the stainless steels lower than that obtained after EP50. This feature is of high importance regarding the use of these steels as biomaterials.
