Abstract
This disclosure, and the exemplary embodiments provided herein, disclose carbon nanotubes (CNT) integrated into 316L stainless steel (SS) powder feedstocks and 3D-printed using selective laser melting (SLM). Ball milling is used to disperse CNT clusters homogeneously onto the surface of 316L SS powders with minimal damage to the CNTs. Hardness increased by 35% and wear was reduced by 70% with the addition of2 vol % CNT, relative to SLM 316L SS. The addition of CNTs increased the water contact angle and retained the desirable corrosion resistance of SLM 316L SS, demonstrating the potential of3D-printed SS-CNT composĀ­ites for use in structural marine applications.
