Synthesis of the (Ti,Cr)xCy carbides on CFs reinforced Cr and Ti-based alloy obtained by direct energy deposition

A new alloy Ti6Al4V/CrCFs synthesized from powder mixture Ti6Al4V and carbon fibers (CFs) coated of chromium (Cr) during direct energy deposition (DED) was investigated. The microhardness, wear properties, and microstructural characteristics of (Ti,Cr) x C y type carbides are determined. Samples Ti6...

Description
Summary:A new alloy Ti6Al4V/CrCFs synthesized from powder mixture Ti6Al4V and carbon fibers (CFs) coated of chromium (Cr) during direct energy deposition (DED) was investigated. The microhardness, wear properties, and microstructural characteristics of (Ti,Cr) x C y type carbides are determined. Samples Ti6Al4V/CrCFs were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and energy dispersive X-ray spectroscope (EDS), respectively. The microhardness of matrix and single carbides (Ti,Cr) x C y of new alloy Ti6Al4V/CrCFs was 450 HV0.01 and 1000 HV0.01, respectively. The (Ti,Cr) x C y synthesized carbides in a sample of the Ti6Al4V/CrCFs alloy grown by the DED method assist to a partial decrease in the coefficient of friction by 1.75 times compared to the Ti6Al4V alloy. This investigation revealed the wear performance of the DEDed specimens Ti6Al4V/CrCFs and their new (Ti,Cr) x C y carbides, which could pave the way for producing components for wear-related applications.
