摘要

研究了低频（46.6 Hz）和高频（21.8 kHz）机械脉冲冲击处理，包括温度暴露（700 ±50 °C）对ZhS6U镍合金的影响。高频（HF）处理形成TiO2层，HF + T可提高显微硬度，减少20%的摩擦。低频处理加加热（LF + T）确保应变均匀化并激活多个滑动面。LF + T提供最高的硬化，而HF通过氧化层提高耐磨性。

Evolution of structural-phase state of nickel alloy surface after shock treatment in different frequency ranges

The influence of low-frequency (46.6 Hz) and high-frequency (21.8 kHz) mechanical-pulse shock treatment, including temperature exposure (700 ± 50 °C), on nickel alloy ZhS6U was investigated. High-frequency (HF) treatment forms a TiO₂ layer, with HF + T increasing microhardness and reducing friction by 20%. Low-frequency treatment plus heating (LF + T) ensures strain homogenization and activates multiple sliding planes. LF + T provides the highest hardening, while HF improves wear resistance via the oxide layer.
