Question Surface modification is used as a way to retain the life of metals when in applications. The common method of preserving a low carbon steel for more than 100 years and still counting has been zinc galvanizing. Currently, surface modification has included layer design; which has changed surface modification to surface engineering. Therefore, surface engineer a type of carbon steel (exclude stainless steel and tool steels) that can be used in high wear applications through a layer deposition method. You can select from surface hardening, surface coating or surface alloying. Also, deposit any type of metal you think will improve the properties of the surface well. Discuss the following: 1. The area where the carbon steel must be used. 2. Importance of the type of surface engineering process. 3. Surface layer deposition procedures. 4. Possible advantages/disadvantages of the deposited layer. [30] END END END
