| Abstract Scope |
Metal dusting is an extreme aggressive form of high temperature corrosion in atmospheres with high C activities causing severe damage to plants e.g. in process industry. A decrease of maintenance and fast solutions in the case of damage are of extreme economic relevance. The latter leads to a great interest in additive manufacturing (AM) of spare parts on-site. Additionally, alloying of commonly used Ni-base materials with Cu was found to reduce the attack since the catalytic deposition of graphite or carbon on the metal and thereby the extremely fast-progressing metal loss is inhibited. Therefore, the metal dusting resistance of Cu-containing Ni-base alloys such as Alloy 400 is investigated in experiments under metal dusting conditions and pressures up to 18bar. The focus is on the difference between the performance of AM samples in comparison to cast alloys. Additionally, different surface pre-treatments were used for the AM samples. |
