The die and mould industry shows a growing interest in the DED family of the additive manufacturing processes. DED processes like LMD are used in manufacturing of moulds with improved functionality and in repair processes. The metallic materials used for LMD processing of the mould components should exhibit good weldability and possess high mechanical properties such as hardness and strength. The properties of LMD samples made out of the Ferro55 material, specially developed for the deposition processes, were investigated intensively. The mechanical properties were measured in as-built, hardened, and tempered samples. The hardness distribution and the variation of the chemical compositions were examined as well. Ferro55 material shows a very high strength and hardness already in as-built condition. These properties exceed the properties of comparable hot forming tool steels like X37CrMoV5-1 (1.2343). Further improvements are achieved through the subsequent heat treatment.

show abstract

Powder-based Laser Metal Deposition offers great opportunities for the manufacturing of components for various applications. To ensure the high load-bearing capacity of these technical parts, the formation of internal defects must be avoided. Thus, appropriate process properties need to be maintained during the entire manufacturing sequence by using suitable processing parameters. In this work, samples are built out of the material Ferro 55. During the building process, the melt pool characteristics are monitored using a CCD camera, whose optical path is coaxial to the processing laser beam. By investigating the obtained images, the melt pool size is selected as a value that allows for the assessment of the deposition process. The correlation of the temporal progression of the melt pool size with metallographic investigations of the samples shows that the formation of lack of fusion defects can be detected as the melt pool size descends below a specific threshold.
