Mechanical and tribological analysis of Ni/TiC powder filled ZA-27 alloy composites (original) (raw)

Materials Today: Proceedings, 2021

Abstract

In the present paper, stir casting technique is used for the fabrication of (0.5, 1, 1.5 and 2) wt. % of nickel and (1,3,5 and 7) wt. % of titanium carbide powder-filled ZA-27 alloy composites with the controlled conditions. The physical, mechanical and tribological properties of the composites, studied experimentally. Both nickel and titanium carbide reinforced composite assists in enhancing the mechanical and physical properties such as impact strength, flexural strength and hardness of ZA-27 alloy matrix. The most significant advantage of the nickel and titanium carbide reinforcement is found in sliding wear properties resulting in better properties of the composite. Various factors such as normal load, reinforcement, sliding distance and sliding velocity considered to optimize wear rate. From Taguchi analysis it has been observed that reinforcement content being the most significant factor in influencing the wear rate followed by the normal load, sliding distance while the least...
