| titleOfInvention | Double-phase stainless steel plasma anode nitriding surface strengthening process |
| abstract | The invention discloses a double-phase stainless steel plasma anode nitriding surface strengthening technology, which comprises the following steps: (1) pretreating the surface of the duplex stainless steel; (2) plasma-assisted anode nitridation: performing surface modification and strengthening treatment on the ultra-low carbon duplex stainless steel disc by adopting a plasma-assisted anode nitriding technology, and putting the duplex stainless steel subjected to surface pretreatment into an anode nitriding device for nitriding treatment; (3) and (6) annealing. The invention can effectively inhibit the formation of brittle phases, enables the surface layer to the core of the disc to have excellent toughness matching, reduces the secondary deformation of a workpiece caused by temperature gradient on the basis of ensuring uniform structure and excellent mechanical property as much as possible, simultaneously can avoid coarsening damage to the treated surface caused by ' arcing ' and ' edge effect ' and the like, is beneficial to the formation of a white and bright metastable compound S phase, inhibits the precipitation of brittle phases such as epsilon-Fe 2-3N and gamma ' -Fe4N and enables the disc to have higher hardness, wear resistance and corrosion resistance. |
