Abstract

Laser-based directed energy deposition (L-DED) offers significant advantages for repairing metal structures, particularly in the marine and offshore industry where corrosion-resistant materials like Monel K-500 (a Ni-Cu alloy) lack strength and wear resistance. This study addresses this issue by producing Monel K-500 with high-strength Stellite 6 (a Co-Cr alloy). Two types of multi-material samples were created using L-DED: interlayered and mixed powder samples. The interlayered samples experienced cracking at the material interface, while the mixed powder samples were crack-free and exhibited improved mechanical properties, with yield strength increasing from 208.3 MPa to 490.2 MPa and ultimate tensile strength from 429.7 MPa to 887.0 MPa compared to single Monel K-500 samples. This research demonstrated the potential of in-situ alloying during the L-DED process to enhance alloy properties and highlighted the challenges of abrupt compositional changes leading to cracking, suggesting mitigation strategies for successful production.

基于激光的定向能沉积 Monel K-500 和 Stellite 6 复合材料

激光定向能沉积技术（L-DED）在修复金属结构方面具有显著优势，尤其是在海洋和近海工业领域，因为在这些领域，像 Monel K-500（一种镍铜合金）这样的耐腐蚀材料缺乏强度和耐磨性。本研究通过在 Monel K-500 中加入高强度 Stellite 6（一种 Co-Cr 合金）来解决这一问题。使用 L-DED 制作了两种类型的多材料样品：夹层样品和混合粉末样品。与单一 Monel K-500 样品相比，夹层样品在材料界面处出现了裂纹，而混合粉末样品则没有裂纹，并显示出更好的机械性能，屈服强度从 208.3 兆帕增加到 490.2 兆帕，极限拉伸强度从 429.7 兆帕增加到 887.0 兆帕。这项研究证明了在 L-DED 过程中原位合金化在提高合金性能方面的潜力，并强调了成分突变导致开裂所带来的挑战，提出了成功生产的缓解策略。
