Students have asked these similar questions
(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).
Figure 4: Drill bit straight flute
I
Explain the surface coating techniques such as plastic coating
and painting, which is used in the surface finishing operations.
Draw a diagram if necessary
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%.
