Özet
Iron aluminides, as a technological material, are a member of multicomponent alloys, that contains other alloying elements besides iron and aluminium. Due to superior anti-corrosion properties at high temperatures, these alloys are used as coating materials in many surface development processes. Copper is widely used in industry because of its commercially desired properties such as high thermal and electric conductivity. However, copper cannot be used for special applications where an excellent strength and/or good wear resistance are required due to a lower tensile strength and poor wear resistance. In this study, 1 wt% TiC reinforced iron aluminide intermetallic composite electrode was initially produced and used to coat the copper surface in order to increase the surface hardness and improve the wear rate by forming a hard structure using ESD coating method. It has been observed that surface hardness increased by about 11 times at the end of experimental studies. Wear rate of the coated material increased compared to the uncoated material while the uncoated sample exhibits adhesive wear, also the coated sample exhibits both adhesive and abrasive wear. The wear rate of the coated material was intially lower due to intrinsic low deformation capacity of aluminide coating and later increased substantially because of removal of this aluminide layer.
