Steels with a high carbon content are considered to be difficult to weld. High carbon equivalent indicates not only problems when joining such steels but also when using them as substrate in additive manufacturing (AM). In this study, the possibility of manufacturing a high-strength steel structure on a high-carbon steel substrate using plasma wire arc additive manufacturing (PWAAM) is demonstrated. This study deals with the thermal history and its effects on the substrate resulting from a multilayer build-up. In-substrate temperature measurements as well as metallographic and hardness measurement will provide an understanding of the influence of the process on the substrate. Additionally, a local pre-heating concept using penetration depth induction (PDI) is considered. PDI also enables energy rearrangement in which energy is removed from the AM process and introduced directly into the substrate by PDI. These variants of the preheating concept are also being investigated concerning their effects on the substrate and its properties. A comparison of multilayer buildup without and with PDI is intended to show the differences but also the possibilities that can be achieved with the PDI approach. The investigations carried out are intended to create the basis for a quality AM structure on a high-carbon steel substrate as well as optimized properties of the substrate. It is also shown that the transition zone between the substrate and the AM structure is not trivial for such a material combination.

碳含量高的钢被认为难以焊接。高碳当量不仅表明连接此类钢时存在问题，而且在增材制造 (AM) 中使用它们作为基材时也存在问题。在这项研究中，证明了使用等离子丝电弧增材制造（PWAAM）在高碳钢基材上制造高强度钢结构的可能性。这项研究涉及多层结构的热历史及其对基材的影响。基材内温度测量以及金相和硬度测量将有助于了解工艺对基材的影响。此外，还考虑了使用穿透深度感应（PDI）的局部预热概念。 PDI 还可以实现能量重新排列，其中能量从 AM 工艺中移除，并通过 PDI 直接引入基板中。预热概念的这些变体也正在研究它们对基材及其性能的影响。对不使用 PDI 和使用 PDI 的多层构建进行比较的目的是展示差异以及使用 PDI 方法可以实现的可能性。所进行的研究旨在为高碳钢基材上的优质增材制造结构以及基材的优化性能奠定基础。研究还表明，对于这种材料组合来说，基板和增材制造结构之间的过渡区并非微不足道。
