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) 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).

Metallography Questions
A. Explain why metallographic samples must be kept cool during cutting and grinding
B. Explain the purpose of mounting samples in materials such as Bakelite.
