Grade 5 titanium !Grade 5 titanium will be used for making the ring. !Grade 5 alloy, Ti 6Al-4V, is the most widely used titanium grade. It contains 6% aluminum, 4% vanadium, 0.25% iron and 0.2% oxygen. This alloy’s strength is very high and so can be used at cryogenic temperatures up to about 800°F (427°C). Ti 64 alloy’s corrosion resistance is based on the existence of a consistent and continuous oxide layer which is formed upon the exposure to oxygen. It has a very good resistance to corrosion in seawater. !!The grade 5 Titanium is resistant to general corrosion but is easily attacked by environments that cause breakdown of the protective oxide layer including hydrofluoric, hydrochloric, sulfuric and phosphoric acids. Because titanium, when exposed to oxygen, creates a layer of ceramic like oxide film, it lends itself to applications where corrosion and erosion resistance are a concern. Should the metal get scratched, as long as it is exposed to oxygen, the scratch will reheal itself with the oxide film.!!

Ring design design of ring which does not tarnish and corrode

Gold plating can be carried out by electroplating. Electroplating involves passing an electric current through a solution called electrolyte. This is carried out by dipping two terminals called electrodes into the solution and connecting them into a circuit so the gold become the positive electrode and the titanium become the negative electrode. When we switch the power on, the copper sulfate splits into ions. Copper ions are attracted to the negative electrode and slowly produce a thin layer of copper plate. The sulfate ions arrive at the positive anode, and release the electrons that move through the battery toward the negative.

Overall, the grade 5 titanium is lightweight and strong, by the fact that it is strong as steel but 40% lighter than it, Corrosion resistance, by it exhibiting excellent resistance to corrosion, capable of withstanding attack by dilute sulfuric and hydrochloric acids, as well as chloride solutions and most organic acids. This is done by forming a!thin layer of titanium dioxide on its surface tat is extremely difficult for these materials to penetrate. It also does’t produce allergic reactions as it is non-magnetic and biocompatible, which led to its increasing use in the medical field. Finally it s a refractory metal, with a high melting point and so makes it self useful as a refractory metal. !

Gold plating Gold is a bright yellow chemical element which is dense, malleable, ductile, and soft. It is precious and very unreactive which means it does not oxidize in the air, so the electrical conductivity stays same over a long time. It has a good corrosion resistance, good solder ability and when alloyed with cobalt, it has very good wear resistance. So if we plate the grade 5 titanium ring with gold, it won’t oxidize nor corrode. Gold plating is better than regular gold jewelry as it is much cheaper when it still attains the same yellow lustre of gold.
