Investigation of Mechanical Properties and Corrosion Behavior of Co-Cr Alloys Fabricated by Direct Metal Laser Sintering with nTopology Design
Keywords:
Co-Cr, DMLS, nTopology, Biomedical applicationsAbstract
Co-Cr alloys are well-known material used in biomedical implants and aerospace due to their excellent mechanical strength and corrosion resistance. Direct metal laser sintering, often known as DMLS, is a method that can be utilized to fabricate intricate and functioning mechanical components via a computer-aided design (CAD) computer model. Mechanical components made using this method typically have poorer mechanical characteristics and more residual porosity than those made using more traditional methods. The present study involved the mechanical properties and corrosion behavior of a nToplogy design integration with DMLS-made Co-Cr-Mo alloy with a composition appropriate for use in biomedical applications. Mechanical properties of microhardness, flexural, compression and corrosion rate were measured for the as cast and DMLS Co-Cr alloy. The findings indicate potential new uses for the DMLS technique in manufacturing mechanical components for the medical and dental industries, particularly in cases where a high level of modification is needed. Co-Cr alloys made using nTopology design had better mechanical characteristics and corrosion resistance than conventionally made material.
