Electron Beam Selective Melting

Additive manufacturing (AM) nickel-based superalloys have been demonstrated to equate or exceed mechanical properties of cast and wrought counterparts but their tribological potentials have not been fully realized. This study investigates fretting wear behaviors of Inconel 625 against the 42 CrMo4 stainless steel under flat-on-flat contacts. Inconel 625 is prepared by additive manufacturing (AM) using the electron beam selective melting. Results show that it has a high hardness (335 HV), superior tensile strength (952 MPa) and yield strength (793 MPa). Tribological tests indicate that the AM-Inconel 625 can suppress wear of the surface within a depth of only ~2.4 μm at a contact load of 106 N after 2 × 104 cycles. The excellent wear resistance is attributed to the improved strength and the formation of continuous tribo-layers containing a mixture of Fe2O3, Fe3O4, Cr2O3 and Mn2O3.

This work is based on the dry sliding wear of Stellite 4-FeSi-B4C composites deposited on a TA10 titanium alloy using a Laser melting deposition (LMD) technique, the parameters of which are such as to provide almost crack-free composites with very low porosity. To our knowledge, it is the first time that Stellite4-FeSi-B4C mixed powders are deposited as the hard composites by the LMD technique. Scanning electron microscope results indicate the nanoscale particles and nanorods are produced in such composites. Furthermore, due to the characteristics of the laser technology, the ultrafine nanoscale polycrystalline phases can be easily produced. Compared with a TA10 alloy substrate, the improvements of the micro-hardness and wear resistance are obtained for such composites.
