Study the Effect of Aluminum Variation on Hardness & Aluminum Loss in Zn-Al Alloy
The objective of this research is to study the hardness &aluminiumloss with percentage variation in Aluminium content added to zinc. As there is a method for coating known as Galfan is available, in which combination of 95%zinc and 5% Aluminium is used for protecting steel from corrosion.As there are not much details available about why this composition is used Zinc-5%Al, we are interested in study of effects of different composition of Aluminum with Zinc, so we study the effect by adding different composition 2.5%,4.5%,6.5%,8.5% & 11.5% Aluminum in Zinc, for this study we are using hot dip galvanizing process for studying this coating. Hot-dip galvanizing is widely used to improve the corrosion resistance of steel. To obtain high-quality coatings, some alloy elements are added to the zinc bath. Aluminum is one of the most important elements in galvanizing.Fe-Al phase diagram indicated thatα Fe is obtained between 1 to 11% of AluminiumGalfan alloy consist of 95% Zn and 5% Al. It was decided to study the effect of variation in Al content in ZincAluminium alloy .Also during melting of this alloy we wanted to observed loss of Al due to oxidation hence the above compositions were decided.
