Abstract
- Fe-based amorphous coatings were deposited on AZ31B alloy and Q235 steel substrates though detonation spray. Parallel comparison experiments on deposition characteristics, residual stresses, interfacial toughness, bonding strengths, three-point bending behaviors, and tribological behaviors of the coatings were investigated to elucidate the deposition mechanisms and mechanical properties of the Fe-based amorphous coatings on magnesium alloy substrates. The results revealed that the coating on the AZ31B substrate was well bonded via physical and mechanical bonding mechanisms, and the interface was found to be highly resilient against interfacial stresses generated from substrate deformations. However, the high thermal conductivity and low hardness of the magnesium alloy hindered the flattening of the sprayed particles during the deposition process, which compromised the bonding strength of the lamellae layers, thus reducing the cohesive strength and the wear resistance of the AZ31B-substrate coating.
