(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).
