Lawrence Livermore National Laboratory - Visit the Industrial Partnerships Office Website
Various methods are disclosed for coating or treating a substrate to enhance resistance of the substrate to at least one of cavitation and liquid impingement. One specific method may involve providing an amorphous metal composition which is able to be atomized. The amorphous metal composition may be applied as an atomized spray to a surface of the substrate via a high velocity spray operation to coat the surface. The coated surface may have at least one of a Vickers hardness number of at least about 1100 HVN, or a yield strength of at least about 700 MPa, or a thermal stability between about C. and about C., and is highly resistant to the effects of cavitation and/or liquid impingement.
