Abstract

A hard facing is produced with particulate wear resistant material bonded by a matrix of substrate material by feeding particulate into a melt pool with a degree of dissolution to produce recrystallised wear resistant material in the matrix. Particulate is fed from a hopper (10) to a delivery chute (27) into a melt pool produced by a TIG electrode (28) in a surface (29) being hard faced (30). The TIG electrode is mounted on a robot arm (25) and moved or scanned over the surface (29) receiving hard facing (30). A magnetic separator (2) removes magnetic materials which might foul electrode (28).
