The addition of zinc to aluminum with magnesium or copper produces heat treatable alloys of highest strength which can be used for structural applications. This work is an attempt to investigate any improvement in hardness and fracture toughness by coating aluminum 7075 alloy with zinc. The zinc coated aluminum 7075 alloy was fabricated using Time Dependent Electro- Plating Technique. The varying thickness of zinc coating was obtained based on the time estimates, which includes 10, 15 and 20 μ. Specimens were prepared according to ASTM standards, which were then tested for mechanical properties such as surface hardness, tensile strength and fracture toughness at different loading conditions. A significant improvement in hardness was seen with the coating, but remained constant for further increase in coating thickness. The yield stress of zinc coated aluminum alloy increased (587.11 N/mm2)when compared to uncoated aluminum alloy 7075 - T6 (537.12 N/mm2), with an increase in brittleness. The fracture toughness test on CT specimen under plain strain condition for coated specimen showed an increase in KIC value by 7.25 % compared to that of uncoated aluminum 7075-T6 alloy. Optical microscopy analysis shows that there is a good bonding of zinc coating on aluminum. © (2014) Trans Tech Publications, Switzerland.

AA7010 Al Alloy is a material in 7xxx series, used in aircraft and automobile industries have high strength to weight ratio. Long term application of the alloy is susceptible to exfoliation corrosion, corrosion fatigue, and stress corrosion cracking. The alloy in T6 condition presents a high strength but susceptible to stress corrosion cracking. To overcome this problem, a multistage heat treatment process was introduced known as Retrogression and Re-aging in which, the alloy is subjected to T6 condition followed by a two stage thermal cycle. The first stage called as retrogression, involves heating to a high temperature for a short period of time followed by quenching. In the second stage, the alloy is re-aged at the same temperature equal to that of T6 condition. The two-stage process thus provides good tensile strength as well as comparable SCC resistance. In the present work, AA7010 alloy forgings were subjected to T6 condition and then retrogressed in a salt bath furnace at temperatures of 200 and 210oC for time periods of 30, 40, 50, 60 and 90 minutes, followed by re-aging. Retrogression temperature and time period of 200oC and 40 minutes respectively were found to be the optimum schedule which gives the best combination of strength and SCC resistance.
