Reducing Thermal Conductivity of (2014- T6&6061) Aluminium alloy using Nickel coating by Electro Deposition method
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 4
Abstract
Nickel coating are employed over the (2014-T6&6061) aluminum alloy to protect it from thermal cyclic load and to improve the performance. Nickel is coated on the aluminum alloy by electro deposition method. This paper deals with conductive heat transfer behavior and hardness behavior of nickel coated aluminum alloy. Hardness behavior and thermal conductivity was determined by brinell hardness testing and specially designed experimental setup respectively.A temperature reduction of nearly 10-14% was observed in aluminium alloy 2014-T6 whereas 12-16% temperature reduction was noticed in aluminium alloy 6061. A hardness increment of nearly 3-7% was observed in aluminium alloy 2014-T6 whereas 11-16% hardness increment was noticed in aluminium alloy 6061. By the nickel coating, thermal conductivity was reduced and the hardness was increased.
