Odporność korozyjna stali C45 po borowaniu dyfuzyjnym i laserowym

Microstructure, chemical composition, wear, and corrosion resistance of FeB–Fe2B–Fe3B surface layers produced on Vanadis-6 steel using CO2 laser

“…Increasing of wear and corrosion resistance, as well as reduction the brittleness of boronized layers can be obtained by modification of these layers using chromium [1,6,7], nickel [8][9][10], and copper [6]. To achieve this purpose, the diffusion methods [1,6,8]; laser methods (e.g., laser hardening [11][12][13], laser remelting [4,7,14], laser alloying [15][16][17], laser cladding [18][19][20][21]); as well as the electroplating [8][9][10] or thermal spraying methods [22] can be applied. Laser remelting of boronized layers allows changes in their microstructure and properties.…”

“…Modification methods of boronized layers include production of single-phase Fe 2 B layers [3], or complex combinations of well-known processes such as nitriding and boronizing [10], nickelizing with boronizing [4], whether, for example chromizing with boronizing [5,13]. Laser modification of surface layers is becoming increasingly popular and widely used [3,4,7,8,[19][20][21][22][23][24][25][26][27][28][29][30][31][32][33]. By using the high energy of laser beam can be modified the diffusion boronized layer, and this way the mild microhardness gradient can be obtained.…”

“…These features are very desired because have positively influence on many properties such as e.g. microhardness and wear resistance [3][4][5][6][7][8][9][10][11][12][13][14][15][16]24,25].…”
