In order to improve the reliability of blades in wet steam stages of steam turbine and prevent blade failure from liquid corrosion, a nonlinear coupling wave model has been developed to investigate the high speed impact between ball liquid droplet and elastic solid, according to a mass of numerical results of impact between liquid droplet and elastic solid made by 1Cr13 which is a typical material for steam turbine blade, the relational expression between dimensionless equivalent peak stress and impact speed mach number is obtained.
It is shown that the analysis model of liquid corrosion fatigue life for blade can give some quantitative results. 0.0 0.5 1.0 0.0 0.2 0.4 0.6 0.8 1.0 X Z 0 0.1375 0.2750 0.4125 0.5500 0.6875 0.8250 0.9625 1.100 0 0.1375 0.2750 0.4125 0.5500 0.6875 0.8250 0.9625 1.100 0.0 0.5 1.0 0.0 0.2 0.4 0.6 0.8 1.0 X Z Fig.3 Fatigue crack initiation life of liquid corrosion under case 1 (left) and case 2 (right) in suction surface (counted by cycles, 7 10× ) Acknowledgements The research work was sponsored by National Natural Science Foundation of China (No. 50336050).

In the literature an approach described to the monitoring of materials under fatigue is related to the application of thin single crystal foils referred to as “smart sensors” [1,2].
One must conclude on a difficulty for composite materials testing using such thin foil sensors in contrast with metals.
The possible solution on overcoming this disadvantage is related to the search of other materials to be used as foil sensors, but this aspect of the work was not studied.
