Daftar Isi:
- Acrylonitrile-butadiene-styrene (ABS) plastic has been widely used for replacement wood, glass and metal materials. However it has some disadvantage such as low in hardness, friction resistance and heat resistance. One of the methods to improve mechanical properties of ABS plastic is using chrome electroplating. In this study, effects of electrical current, electroplating time and the type of solution to the mechanical properties of ABS plastic was investigated. ABS plastic as specimen was activated, before chrome plating by palladium and electroless nickel plating. In chrome electroplating process electrical currents, electroplating time and composition of solutions were varied. Some measurements such as micro hardness, friction resistance, surface roughness, layer thickness test were conducted in order to compare the results before and after chrome electroplating process. Chrome electroplating on ABS plastic improved surface hardness, surface roughness, friction resistance and chrome layer thickness of the specimen. The highest values in surface hardness, friction resistance and layer thickness are obtained on specimens using solution II, 6 ampere and 15 minutes.
