概要
The erosion rate of aluminum material by liquid droplet impingement erosion is studied by using high speed spray. In order to propose an accurate prediction method, a new experimental data are obtained by using the spray erosion larger than the scale of specimen, which allo ws a constant erosion rate, while it is not for the previous method. The new experimental data shows that the erosion rate is proportiona l to the power of 7 of the droplet velocity, which results in a highly accurate prediction method for liquid droplet impingement erosion.
