【 摘 要 】

The energy-boosting of hydraulic turbines by improving efficiency and service life is a continuing concern of this century when trying to move from a fossil fuel polluting energy to a wider use of electric power to propel cars. Increased performance of these hydraulic turbines can be achieved by depositing thin, hydro-abrasion-resistant, thin layers. In this paper we will analyze mechanically and structurally thin, adherent-hard layers that have been deposited on a special stainless steel. The aim is to increase the energy efficiency of hydraulic turbines by increasing the hydro-abrasion resistance of the blades. The deposits are made with plasma-based thermal spraying powders/electrodes. The microstructural tests will consist of optical and SEM microscopic analysis of the deposited material and layer, and the mechanical ones will consist of the analysis of elasticity and adhesion.
