Abstract |
|
An investigation was carried out to assess the effect of the Ni and Cr content on the hardness of Cu-Zn brass alloy. The procedure for the study is carried out first by coating brass alloys with thin layers of chromium and chromium above nickel. The surface refining of the coated brass was done using the Gas Tungsten Arc Welding (GTAW) as heat source. Hardness evaluation of the refined layer was conducted using a Vickers Hardness Tester. It was found that the hardness of the modified layer shows an increase when compared to the hardness of ordinary brass alloy .This is due to refined grain structure of the modified layer as compared to the coarse dendritic structure observed in the brass alloy sample. |
