Improving Oxidation Behavior of (Alpha- Beta) (Cu-Zn40) Brass by Aluminum Addition
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2019, Vol 9, Issue 1
Abstract
Brass alloys with a zinc content of 35 % and more have a mixture of the alpha (FCC) and beta (BCC) phases, that causes an increasing in hardness significantly. Further, this alloy can be formed only by hot-working. Therefore, it appears problematic of oxidation at high temperature. This leads to create an idea of improving oxidation behavior of the α+β (Cu-Zn40) brass alloy by adding different amounts of aluminum(1, 3 and 5) wt %. Cyclic oxidation tests were conducted on the α+β (Cu-Zn40) brass with and without aluminum in the air at temperatures range between 500-700°C for 18 hours at 6 hours cycle. All specimens exhibited parabolic oxidation rate dependence and the value of Kp for ( α+ β) (Cu-Zn40) brass alloy with aluminum is nearly lower than that for(α+β) (Cu-Zn40) brass alloy under the same condition. The phases appear in the cyclic oxidation of α+β (Cu-Zn40) brass surface after addition of aluminum under further most test situations as exposed by XRD examination are (Al2O3, ZnO, CuO).
