一种表面改性的核电站稳压器喷雾器旋水芯
摘要：
本发明提供一种表面改性的核电站稳压器喷雾器旋水芯，其包括：旋水芯主体，其为圆柱状；及旋水分流板，其沿所述旋水芯主体的圆周方向均匀分布，且包括至少两个螺旋叶片；其中相邻的所述螺旋叶片围成螺旋槽流道，且所述表面改性的核电站稳压器喷雾器旋水芯经配置以进行表面改性处理。本发明提供的表面改性的核电站稳压器喷雾器旋水芯，在采用不锈钢制造成形后进行表面非金属离子渗入处理，心部具有良好的韧性且表面具有良好的耐磨性、耐腐蚀性和抗疲劳性，能够有效提高喷雾器的寿命和运行可靠性，并且这种提高旋水芯耐磨耐腐蚀耐疲劳性的表面改性技术工艺简单、生产效率高、制造成本低。
摘要（英）：

The invention provides a surface-modified nuclear power plant voltage stabilizer sprayer rotary water core. The surface-modified nuclear power plant voltage stabilizer sprayer rotary water core comprises a rotary water core body which is cylindrical, and rotary water flow separation plates uniformly distributed in the peripheral direction of the rotary water core body and comprising at least two spiral blades, wherein the adjacent spiral blades surround a spiral groove runner; and the surface-modified nuclear power plant voltage stabilizer sprayer rotary water core is configured for surface modification. The surface nonmetal ion permeation treatment is performed on the surface-modified nuclear power plant voltage stabilizer sprayer rotary water core after manufacturing by stainless steel,so that the center part is excellent in toughness, the surface is excellent in wear resistance, corrosion resistance and fatigue resistance, and the life and the operation reliability of a sprayer canbe effectively improved; and the surface modification technology for improving wear resistance, corrosion resistance and fatigue resistance of the rotary water core is simple, high in production efficiency and low in manufacturing cost.
