Influence of the deposition parameters on the tribological behavior of cold gas sprayed FeMnCrSi alloy coatings

Cold Spray deposition process may be an alternative for the High-Velocity Oxy-Fuel (HVOF), providing high kinetic energy without particles oxidation. In this work, an FeMnCrSi alloy was deposited onto carbon steel substrate by Cold Gas Spray (CGS) process varying spraying parameters (working gas, it...

Description
Summary:Cold Spray deposition process may be an alternative for the High-Velocity Oxy-Fuel (HVOF), providing high kinetic energy without particles oxidation. In this work, an FeMnCrSi alloy was deposited onto carbon steel substrate by Cold Gas Spray (CGS) process varying spraying parameters (working gas, its pressure and temperature). Cavitation resistance was evaluated by ultrasonic cavitation testing, and the sliding wear resistance was studied by ball on disk testing, with intent to understand the behavior of this coating when exposed to sliding wear condition. FeMnCrSi sprayed using N2 working gas at 1000 °C showed higher hardness, elastic modulus, cavitation resistance, and sliding wear resistance than FeMnCrSi deposited with 900 and 1100 °C. The samples deposited with N2 at 1000 °C and He at 600 °C showed higher compressive residual stress and flatenning ratio also. The tests were performed for CGS sprayed 316 L stainless steel, which is used as a benchmark material. •CGS deposited with N2 at 1000 °C promoted higher compressive residual stress and higher flattening ratio.•CGS samples with higher flattening ratio showed higher toughness compressive residual stress.•Higher cavitation resistance occurs due to higher compressive residual stress and higher fracture toughness.•Higher sliding resistance occurs on the CGS coatings with lower CoF.
