In this study, aluminum powders were
deposited using two different cold spray processes
which are high pressure cold spray process (HPCS) and
low-pressure cold spray process (LPCS). The main
objective is to investigate and compare the
microstructure, mechanical and wear properties of
aluminum coatings using HPCS and LPCS processes.
The microstructure, hardness, wear and elemental
composition were evaluated using Scanning Electron
Microscope, Vickers Hardness test, pin-on disc wear test
machine and Energy-dispersive X-ray spectroscopy,
respectively. It was found that the aluminium coatings
using LPCS process exhibited slightly better mechanical
and wear properties compared to the aluminium
coatings using HPCS process.
