Surface engineering of advanced composite coatings for significant enhancement to the life cycle of HydroPower infrastructure

与任何其他电厂一样，在水电站中，部件故障通常会导致高昂的维护和维修成本；因停机和更换电力而损失的收入；运营效率降低；以及设备使用寿命的缩短。有几种方法可以最大限度地减少液压系统中磨料流的影响，即：i.改进的流型设计，ii.对裸露材料进行表面处理，以增加耐腐蚀性，以及防腐涂料的应用。在NSERC-Strategic项目中，我们建议i)在SS444/SS309基板上制造两代自润滑复合涂层，ii)量化它们的腐蚀性能，iii)研究它们的摩擦学特性，iv)开发预测腐蚀模型，以帮助魁北克水电公司(HQ)进行技术开发。

In hydropower plants like any other plants, part failures normally contribute to high maintenance and repair costs; revenue lost due to downtime and cost of replacement power; decreased operating efficiencies; and reduction of equipment service life. There are several avenues to minimize the effect of abrasive flows in hydraulic systems, namely i. improved flow profile design, ii. surface treatment of exposed materials to increase erosion resistance, and iii. application of erosion-resistant coatings. In this NSERC-Strategic project we propose to i) manufacture two generations of self-lubricating composite coatings on SS444/SS309 substrate, ii) quantify their corrosion properties, iii) study their tribology properties, and iv) develop predictive corrosion models that will aid Hydro Quebec (HQ) in their technology development.
