Characterization of egg shell powder-doped ceramic–metal composites

Abstract

Titanium is known to be an indispensable element in biomaterials. In this study, boron carbide was considered as an alternative to titanium due to its good mechanical properties. Boron carbide has high temperature resistance, high wear resistance, etc. It is a preferred material due to its properties. Considering this information, different compositions were created by mixing Fe–B4C and egg shell powders. Compositions sintered using powder metallurgy technique were investigated mechanically, physically and metallographically. According to the results of the analysis, it was determined that the hardness increased by 13.75% with the addition of egg shell. The hardness value of 204.12 HB was measured in the sample sintered at 1,400°C by adding 6.66% egg shelter powder.
