“…Result of metallographic analysis: Under different machining parameters, the processed surface had no light-colored remelted layer separated from the main structure [ 52 ] and no microcracks extended inside. This indicates that the surface after electrolytic milling has no microscopic defects and exhibits good mechanical properties.…”

Titanium matrix composite (TiB+TiC)/TC4 has excellent physical properties and is a completely new composite material with great application prospects in the next generation of the aerospace field. However, there are problems, such as tool loss and material overheating, when using conventional processing methods. Electrochemical milling is a low-cost, high-efficiency processing method for difficult-to-machine metal materials with no tool wear. In this research, the feasibility of the electrochemical milling of (TiB+TiC)/TC4 and removal mechanisms during processing was reported for the first time. The feasibility of electrochemical milling is verified by the current efficiency experiment and basic processing experiment. Through the adjustment of the processing parameters, the final material removal rate increased by 52.5% compared to that obtained in the first processing, while the surface roughness decreased by 27.3%. The removal mechanism during processing was further performed based on the current efficiency experiment; three stages were observed and concluded during the electrolytic dissolution. This research proved that electrochemical milling is an excellent low-cost method for roughing and semi-finishing (TiB+TiC)/TC4 composites and provides guidance for better electrochemical milling in the titanium matrix composites.

Electrochemical micromachining refers an unconventional technology in the field of machining. With this technology, the ultrashort pulse power supplies are extensively used to address the issue of excessive machining of non-processing areas. However, the reduction of pulse duration is the only effective strategy to enhance the processing accuracy in ultra-short pulse electrochemical microfabrication. Nonetheless, the high cost of equipment and unsuitability in practical production has limited its progress. To resolve this issue, this paper proposes the use of a composite signal in electrochemical micromachining instead of ultrashort pulses. By changing the signal waveform during machining, the energy required for processing can be reduced with the same electromotive force input, thereby reducing the current used to decompose the anode in the circuit and effectively improving machining accuracy. This approach was employed to manufacture micro-structures on a pure nickel sheet, achieving micron-scale accuracy. Moreover, the same level of superior machining accuracy can be achieved when machining micro-structures on hard-to-cut super alloy plates.

“…Titanium alloy has the reputation of 'marine metal' due to its low density, high strength, non-magnetic and strong toughness. It is widely used in naval vessels, ships, drilling and other marine related fields [1][2][3]. Inspired by lotus leaf, Hydrophobic or superhydrophobic surfaces with micro textures have been widely prepared, and the surfaces have shown great application value in self-cleaning, antifouling, anti-icing, drag reduction and corrosion resistance [4,5].…”

TIn order to obtain higher contact angles and improve the hydrophobicity of titanium alloy, the micro pit arrays were fabricated by the through-mask electrochemical micromachining (TMEMM). The theoretical model of surface hydrophobicity between the contact angle and the geometry size of micro pit arrays was developed. Moreover, the multi physical field coupling simulation of TMEMM was carried out. Thus, the direct mapping relationship between the contact angle and the process parameters was obtained by combining the theoretical model with the simulation results. The effect of process prameters, such as electrolyte mass fraction, mask size and processing voltage, was investigated. The optimal combination of process parameters was predicted and verified by experiments. The results show that the errors of the measured values of diameter, spacing, depth and surface contact angle of the micro pit arrays are 2.49%, 6.87%, 7.40% and 6.01% respectively, which indicates that the hydrophobic textured surface with a contact angle of about 141° is successfully fabricated without the modification of low surface energy materials.
