Patent number: 8119950Abstract: The present invention relates to hard coating of ferrous metal substrates using a laser beam with diamond particles in a metal matrix produced from precursor powders of metals which bond to the diamond particles and to the ferrous substrate. The hard coating is particularly useful for white iron castings for pumps (200) used in piping tar sand and water mixtures.Type: GrantFiled: January 10, 2008Date of Patent: February 21, 2012Assignees: Fraunhofer USA, Fraunhofer IWSInventors: Eric Stiles, Thomas Himmer, James E. Herbison, Anja Techel
