Abstract
An impeller blade that includes an impeller blade body constructed of a first material. The impeller blade body defines a leading edge that faces a direction of rotation. A second material couples to the leading edge. The second material is a more erosion resistant material than the first material. The second material extends over the leading edge a distance to absorb high angle impacts of droplets and/or particulate. A third material couples to at least a portion of the impeller blade body.
