Abrasion Resistance and Surface Hardness of Gold Plated Carbonized Board

This research was performed to evaluate surface performance of gold plated carbon-ized board. After the carbonization at 850°C, volume, weight, and density decreased by 65.25%, 71.35% and 17.64%, respectively. Abrasion resistance and surface hardness of non-carbonized board exhibited the highest values of 0.093 g/100 revolution and 26.43 N/mm2, respectively. Gold plated carbonized board showed intermediate values, 0.587 g/100 revolution of abrasion resistance and 24.35 N/mm2 of surface hardness. Carbonized board showed the lowest values, 0.863 g of abrasion resistance and 21.50 N/mm2 of surface hardness. These results were thought to reflect propertional relationship between abrasion resistance and surface hardness. Abrasion resistance and surface hardness of carbonized board appeared able to be improved by surface treatment such as plating.
