A1 & A2: as-deposited onsite - red line indicates the “wavy” formation of the Cr layer; B: as-simulated per same process and tooling settings as A - different colors stand for different Cr thicknesses, where red indicates overplating and blue stands for underplating; C: as-simulated per improved process and tooling setting. Hard Cr deposit over one of the critical shaft’s diameters v Industrial hard chrome plating is a rather complex, lengthy and labour- intensive process: typically, the low cathodic current efficiency of Cr plating baths results in limited deposition rates, taking an hour to deposit a thickness of 25 µm on any size of the part. In the majority of cases, the hard Cr plating process requires the use of tooling structures, making the process strongly operator-depen
