Abstract

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.
