| Abstract: | In this study, a method of cold-spray-assisted synthesis of high-aluminum bronze alloy coating is proposed, and a high-aluminum bronze coating is prepared on 45 steel matrix. The corrosion resistance of the alloy coating was measured with the CHI660D electrochemical test system by analyzing the micromorphology and phase tissue of the coating by SEM, EDS and XRD. The results show that after induction remelting, the in situ synthesis tissue of cold spray metal mixed coating is a high aluminum bronze alloy coating of beta-phase, alpha-phase, gamma-2-phase and k-phase, with dense coating and low porosity. The high aluminum bronze alloy coating in situ has good mechanical properties and wear resistance, corrosion resistance, and the performance of cast block high aluminum bronze alloy is close. The hardness of the coating is 357.0HV and the dry friction coefficient with alumina is 0.320. The stable voltages in 3.5wt.%NaCl and 5.0wt.%H2SO4 corrosion media were -366mV and -387mV, respectively. |
