In this work, investigations on Inconel 718 cladded H13 and 4140 have been carried out using two different cladding methods: Direct Metal Deposition (DMD) and Laser Hot-Wire (LHW). Heat treatments were conducted to optimize mechanical properties using Vickers microhardness as the primary metric. Electron microscopy and X-Ray Diffraction were used to analyze cladding composition and microstructure. DMD Inconel on 4140 demonstrated severe iron depletion adjacent to the substrate. Hardness increases from 278 HV to 438 HV and 312 HV to 465 HV were achieved for DMD samples by high-temperature solutionizing and ageing for the 4140 and H13 substrate systems respectively. High-deposition power LHW cladding showed high cladding dilution by the substrate and a much lower as-cladded average hardness of 200 HV which was unresponsive to heat treatment. Low-deposition power LHW cladding displayed less dilution and higher as-cladded hardness of 304 HV. Results demonstrate feasibility for cladded die system improvement.
