- Explain the surface finishing operation in which stainless steel spoon is coated with silver.arrow_forwardA part made of sheet steel is to be nickel plated. The part is a rectangular flat plate that is 0.075 cm thick and whose face dimensions are 14 cm by 19 cm. The plating operation is carried out in an acid sulfate electrolyte, using a current = 20 amps for a duration = 30 min. Determine the average thickness of the plated metal resulting from this operation. Assume, C= 3.42 x 102 mm/A-s, cathode efficiency E = 95%.arrow_forward(a) Figure 4 shows a HSS drill bit to be coated with TiN coating using either PVD or CVD coating proces.
