Abstract:
A machine component (12) includes a body made of cast iron. The body may include a surface (24) configured to be subject to cavitation-induced erosion. The component may also include a hardened covering (42) on the surface of the body. The covering may have a crystal structure including martensite and between about 5% to about 40% austenite.
