The corrosion resistance of slag-free self-shielded flux-cored welding overlays with different ferrotitanium (Fe-Ti) additions in 3.5 wt.% NaCl + 0.01 mol/L HCl acidic solution was investigated. The corrosion occurs in the matrix rather than M 7 (C, B) 3 , M 3 (C, B) and TiC in the microstructure of all the welding overlays. The corrosion resistance of hypereutectic welding overlay is decreased when the Fe-Ti addition is increased from 0 wt.% to 12 wt.%. The corrosion resistance of the welding overlay is the lowest since the overlay is a eutectic structure at the Fe-Ti addition of 12 wt.%. The eutectic structure increases the interface of corrosion reaction, which accelerates the corrosion rate and increases the corrosion current. With the Fe-Ti addition increasing from 12 wt.% to 24 wt.%, the corrosion resistance of the welding overlays with hypoeutectic structure is gradually increased, owing to the increase of the proportion of TiC and chromium content in the matrix.

“…Mn–Cu alloy was once regarded as an ideal material for propeller damping, shock absorption, and noise reduction due to its excellent damping and mechanical properties [ 11 , 12 , 13 ]; however, due to its severe shrinkage porosity and poor stress corrosion and corrosion fatigue resistance, Mn–Cu alloy still faces challenges for application in the field of propeller manufacturing [ 12 , 14 ]. Current marine propeller materials are still mainly nickel–aluminum bronze (NAB) and composite materials [ 15 , 16 , 17 , 18 , 19 , 20 , 21 ]; Mn–Cu damping alloys have not been widely used.…”

Marine noise pollution generated by propellers is of wide concern. Traditional propeller materials (nickel–aluminum bronze (NAB) alloys) can no longer meet the requirements for reducing shaft vibration. However, the Mn–Cu alloy developed to solve the problem of propeller vibration is affected by seawater corrosion, which greatly limits the application of the alloy in the field of marine materials. In this study, the M2052–NAB gradient alloy was developed for the first time using LENS technology to improve the corrosion resistance while retaining the damping properties of the M2052 alloy. We hope this alloy can provide a material research basis for the development of low-noise propellers. This study shows that, after solution-aging of M2052 alloy as the matrix, the martensitic transformation temperature increased to approach the antiferromagnetic transformation temperature, which promoted twinning and martensitic transformation. The aging process also eliminated dendrite segregation, promoted the equiaxed γ-MnCu phase, and increased the crystal size to reduce the number of dislocations, resulting in obvious modulus softening of the alloy. NAB after deposition had higher hardness and good corrosion resistance than the as-cast alloy, which offers good corrosion protection for the M2052 alloy. This research provides new material options for the field of shipbuilding.

Electroless plating is a commonly used method to enhance the corrosion resistance, wear resistance, and decorative performance of aluminum alloys. However, in electroless plating processes, it is customary to maintain the solution temperature at levels exceeding 85°C, a critical condition that ensures a sufficiently rapid deposition rate and thereby fosters the formation of high-performance coatings. Conventional immersion pretreatments with zinc and palladium result in lower deposition rates at low temperatures. This study shows that a copper immersion layer with microporous channels can facilitate the electroless plating process for aluminum alloys at lower temperatures. Through a redox reaction in a Cu2+-containing solution at 70°C, a copper immersion layer with a microporous structure could be created on an aluminum alloy. The microporous channels between the copper immersion layer and the aluminum alloy create electrochemical corrosion cells in the plating solution, accelerating the electroless plating process. The Ni-P coating obtained after pretreatment by copper immersion has a higher hardness (578 HV) and a lower corrosion current density (0.55 μA/cm2). This work provides a practical method to rapidly fabricate high-performance Ni-P coatings at intermediate temperatures (70-75°C).
