What are the problems while the space shuttle enters the atmosphere? What are the selection requirements for the materials that are used for wing coating structure? Select the proper material. Explain your reasons.
A 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%.
(a) Figure 4 shows a HSS drill bit to be coated with TiN coating using either PVD
or CVD coating proces. There is a requirement from the client; the product
must be coated with a coating process that will not change its properties and will
maintain its sharp edge on all sides. Considering the special requirement from
the client:
i. Propose the appropriate coating process to be used for this product.
ii. Justify your answer in (i).
