%X The relationship between erosion rate of fusion-bonded epoxy powder coating and the flow velocity,and the influence of the content and size of sand in water based slurries on the exponent of the flow velocity have been investigated by using modified rotating disk rig.The results showed that erosion rate of the coating increased according to a power law with the flow velocity ( V ) under different test conditions,namely E=KV n .With the increase of sand content the exponent of flow velocity decreased and then reached a constant value.With the increase of sand size,firstly,the exponent of flow velocity decreased and increased consequently,there exists a minimum exponent of flow velocity.The erosion mechanism of the coating included microcut and plastic deformation and the later was dominant.
