Abstract
ZA 27 alloy;
Molybdenum disulfide (MoS2);
SEM
The present investigation aims to study the mechanical properties of ZA- 27alloy/ Molybdenum disulfide composites containing Molybdenum disulfide (MoS2) particles of size 40 µm. 1% and 2% of molybdenum disulfide are reinforced with ZA 27 alloy (which mainly consists of Aluminium 27%, Copper 0.5%, Tin 1-2% balance is Zinc) through the stir casting method. In this method, MoS2 particles are poured into the molten ZA 27 alloy, for the uniform distribution of the particle stirrer used. The results of the present investigation showed that as MoS2 composition increased, there were significant monotonic increases in the elastic load strength, plastic load strength, ultimate tensile strength (UTS) and compressive strength of MoS2-reinforced ZA27 alloy as compared to unreinforced ZA 27 alloy. The present work gives explanations for these obtained results with the help of Scanning Electron Microscope (SEM) images.
