Abstract

Laser Additive Manufacturing Directed Energy Deposition (LAM-DED) technology is a promising process for the maintenance and repair of ductile cast iron components. LAM-DED can produce high quality results compared to conventional welding processes. This is due to a narrow and specific heat-affected zone (HAZ) and a strong interface between the base material and filler, caused by reduced heat input with the high energy density. This method also maintains the composition of the clad material in the repair zone and deposits small volumes of filler in specific areas.This paper presents a succinct review of metallic powder alloys as cladding materials for the repair and maintenance of cast iron components. It introduces commercial additive manufacturing (AM) powders used as filler materials for laser cladding of cast iron components, discussing the evolution in microstructure, phase transformation, mechanical properties, and processing issues. This paper summarizes LAM-DED of AM powders for cast iron components and will be a helpful reference for researchers and industry professionals. Key words: LAM-DED process, Laser cladding, Repair & maintenance, Cast iron, AM metal powder
