“…It is clear for initial material -austenitic stainless steel. In the case of modified material peaks characteristic for fcc structure confirm that after remelting and alloying with REE austenitic phases are still present in the surface layer of steel [13,14]. HIPPB modified AISI 316L steel with different doses of incorporated REE reveals smaller value of linear wear as compared with the initial material (Fig.…”

“…There is no difference observed when Ce or La was used. Obtained results showed the bigger improvement of tribological properties for higher REE concentrations Authors suppose that improvement of tribological properties is connected with following reasons: (i) fine grains formation in the modified material as a result of very high cooling rate ii) enrichment of grain boundaries with REE (iii) nitrogen presence of modified layer [13,14].…”

The plasma beams were generated in a Rod Plasma Injector (RPI) operated in the Deposition by Pulsed Erosion (DPE) and Pulse Implantation Doping (DPE) modes. Samples of unalloyed and austenitic stainless steels were irradiated with short (μs scale) intense (energy density 2.0-5.0 J/cm2) pulses. The near surface layer - thickness in μm range - was melted and simultaneously doped with active element like nitrogen, cerium and lanthanum. Heating and cooling processes were of non-equilibrium type. The most important obtained results were: (i) austenitic structure was present in unalloyed steels after HIPPB modification processes and (ii) modified surface layers of austenitic stainless steel showed significant improvement of tribological properties and increase of high temperature oxidation resistance as compared with initial material.

“…Irradiation of solids with so-called plasma-ion beams is a strongly nonequilibrium process, which enables a number of effects that are impossible to achieve with other methods [2]. These include improvement of wettability of ceramics [3][4][5], production of stable copper-ceramics interfaces [6], production of stable Ni-Cu and Al-Cu interfaces [7], improvement of properties of zirconium alloys [8], improvement of tribological properties of stainless steel [9], improvement of high temperature oxidation resistance of stainless steel [10], modification of superconducting and electrical properties of Mg-B structures [11], improvement of manganese distribution in Si with He + and H + plasma pulse irradiation [12], doping metals with nitrogen [13], and photovoltaic junction formation [14].…”

Irradiation of a solid with intense plasma-ion beams produced within a high vacuumchamber (by the so-called Rod Plasma Injector [1]) is a strongly nonequilibrium process, which enablesachieving a number of effects which are impossible to be achieved with other methods. These are,amongst other: improvement of ceramics wettability, fabrication of stable copper-ceramics interfacesand stable Ni-Cu and Al-Cu interfaces, improvement of tribological properties and high temperatureoxidation resistance of stainless steel, photovoltaic junction formation, and many others. In the paper,the process of plasma-ion beam propagation regarding its time and energy distributions and the processof ion penetration of solids, resulting with ion implementation and temperature growth have beenanalyzed mathematically on basis of experimental data. Results of numerical calculations have beenpresented concerning temperature and dopant density time evolution.

“…Improvement of the wear resistance of austenitic stainless steels can be achieved using enrichment of the surface layer with reactive elements. It is well known that high oxygen affinity elements such as Y, Ce, La, Er and other rare earth elements (REE) added to steels in small amounts can improve their resistance to electrochemical corrosion [1], high temperature oxidation [1][2][3][4][5][6], wear [7,8]. The amount of REE addition has to be precisely controlled.…”

“…If the REE addition is too highthe negative effects are observed, like embrittlement increase and mechanical properties deterioration. REE can be incorporated into the surface area of materials using different methods of surface treatment: ion implantation [1,3,4], plasma immersion ion implantation [2], solgel coating [4,9], metal organic chemical vapour deposition [10][11][12][13], plasma beams application [2,5,14], pack cementation [3]. * corresponding author; e-mail: b.sartowska@ichtj.waw.pl…”

Stainless steels with their very good corrosion resistance are used in nuclear, petrochemical, chemical, pulp and paper chemical industries as well as in food processing and others. Unfortunately, poor tribological properties of this kind of steel can be the limitation in the situations in which wear can be responsible for material degradation, like corrosion-erosion. Improvement of the wear resistance of austenitic stainless steels can be achieved using different methods of surface modification, for example: enrichment of the surface layer with reactive elements. Rare earth elements were implanted to AISI 316L austenitic stainless steel using the MEVVA type implanter (65 kV). Different rare earth elements implanted doses: 10 15 , 5×10 15 , and 5×10 16 ion/cm 2 were applied. Initial and modified surfaces were investigated using scanning electron microscopy, elemental analysis with the energy dispersive spectroscopy method, X-ray diffraction analysis and the Rutherford backscattered spectroscopy. Tribological properties were investigated using the Amsler method. The most important result was that the surface layers of AISI 316L steel implanted with rare earth elements showed improvement of tribological properties as compared with the initial material.
