In this article we article we will discuss about the metallic and non-metallic types of coating metals. Cost is a very important factor while choosing an engineering material. In majority of applications of metals, the importance of the corrosion factor does not warrant the use of expensive corrosion-resistant alloys. Thus, when an easily corrodible alloy like steel is used, some [...]
The following points highlight the twelve main methods adopted for coating of metals. The methods are: 1. Hot Dipping 2. Galvanising 3. Tin Plating 4. Lead Coating 5. Metal-Cladding 6. Diffusion 7. Sherardizing 8. Calorising 9. Chrome-Diffusion 10. Siliconising 11. Anodising 12. Parkerizing. Method # 1. Hot Dipping: Hot dipping coatings can be used for coating high melting point metals [...]
The following points highlight the four main techniques involved in the modification of surface in coating of materials. The techniques are: 1. Ion-Beam Based Techniques for Surface Modification 2. Thin-Film Vapour Phase Deposition Techniques 3. Plasma Treatments 4. Laser Treatment for Surface Modification by Surface Alloying. 1. Ion-Beam Based Techniques for Surface Modification: The useful life of many materials is [...]
