【摘要】：解決水輪機過流部件的磨蝕問題是高泥沙含量河流建設水電站的重要課題。采用超音速火焰熱噴涂技術與納米改性技術相結合,在水輪機過流部件基材上制備納米WC抗磨蝕陶瓷涂層,通過對磨、電化學、沖蝕等試驗,檢驗該涂層性能。結果表明:該納米WC陶瓷涂層具有遠高于基材的顯微硬度、耐磨性能以及耐沖蝕性能,與基材之間形成高強度的結合。通過機器人模擬耦合技術實現良好的曲面編程,確保涂層性能的穩(wěn)定。將其應用到新疆卡拉貝利水電站等高泥沙河流電站的機組過流部件表面,具有顯著的抗泥沙磨蝕效果。
[Abstract]:It is an important task to solve the problem of erosion of hydraulic turbine overflow components in construction of hydropower stations with high sediment content rivers. By using supersonic flame thermal spraying technology and nano-modification technology, nano-WC antiwear ceramic coatings were prepared on the substrates of hydraulic turbine overflowing parts. The properties of the coatings were tested by abrasion, electrochemical and erosion tests. The results showed that the nano-WC ceramic coating had much higher microhardness, wear resistance and erosion resistance than the substrate, and formed a high strength bond with the substrate. Good surface programming is realized by robot simulation and coupling technology to ensure the stability of coating performance. It is applied to the surface of the unit flow parts in the equal-height silt river power station of Karabel Hydropower Station, Xinjiang, and has a remarkable anti-sediment erosion effect.
