Due to the inhibiting behavior of Cu, NiCu alloys represent an interesting candidate in carburizing atmospheres. However, manufacturing by conventional casting is limited. It is important to know whether the corrosion behavior of conventionally and additively manufactured parts differ. Samples of binary NiCu alloys and Monel Alloy 400 were generated by laser powder bed fusion (LPBF) and exposed to a carburizing atmosphere (20 vol% CO–20% H₂–1% H₂O–8% CO₂–51% Ar) at 620 °C and 18 bar for 960 h. Powders and printed samples were investigated using several analytic techniques such as EPMA, SEM, and roughness measurement. Grinding of the material after building (P1200 grit surface finish) generally reduced the metal dusting attack. Comparing the different compositions, a much lower attack was found in the case of the binary model alloys, whereas the technical Monel Alloy 400 showed a four orders of magnitude higher mass loss during exposure despite its Cu content of more than 30 wt%.

由于 Cu 的抑制行为，NiCu 合金在渗碳气氛中是一个有趣的候选者。然而，通过传统铸造的制造是有限的。了解传统制造和增材制造部件的腐蚀行为是否不同非常重要。二元 NiCu 合金和蒙乃尔合金 400 的样品通过激光粉末床熔化 (LPBF) 生成并暴露于渗碳气氛（20 vol% CO–20% H ₂ –1% H ₂ O–8% CO ₂–51% Ar) 在 620 °C 和 18 bar 下保持 960 小时。使用多种分析技术（例如 EPMA、SEM 和粗糙度测量）对粉末和印刷样品进行了研究。建造后研磨材料（P1200 砂砾表面光洁度）通常会减少金属粉尘的侵袭。比较不同的成分，发现二元模型合金的侵蚀要低得多，而技术蒙乃尔合金 400 尽管其 Cu 含量超过 30 wt%，但在暴露期间的质量损失却高出四个数量级。
