Abstract
The present invention relates to a component of a concrete delivery system comprising a substrate made of relatively thin gauge carbon steel or aluminum, and a protective coating of amorphous, nano or near-nanoscale steel, or mixtures thereof, overlying the substrate, wherein the coating may be formed by thermal deposition process from multi-component glass forming steel alloys. The protective coating may also be heat treated to increase wear life.
