PENGARUH VARIASI ARUS PELAPISAN KHROM PADA PLASTIK ABS DENGAN METODE ELEKTROPLATING
Abstract
Plastic is one of the materials used as an alternative to metal because plastic material has many superior properties, such as corrosion resistance, relatively cheap prices, and light weight. To improve the quality of plastic, surface treatment is carried out by electroplating method to add plastic, artistic and decorative conductive properties. In this study the material to be used is ABS (Acrylonitrile Butadiene Styrene) plastic with an electroplating process using current variations 11A, 16A and 22A The purpose of this study was to determine the effect of chromium electroplating on ABS plastic by testing surface hardness, surface hardness and structure microstructure produced from the chromium electroplating stage of the specimen.
In the electroplating process various processes are needed, namely, surface preparation, metallization process, then proceed with the electroplating process, and in this study the current variations in the chrome electroplating process with currents 11A, 16A, and 22A. The electroplating process can also increase surface hardness, adding to the decorative value of the material, in addition to adding electricity.
Chrome electroplating process with current variations of 11A, 16A and 22A obtained results in surface roughness values and surface thickness tends to increase. Based on this study the best results were obtained on 16A chrome electroplating coating with a surface roughness value of 0.401 μm, surface hardness of 144.1 shore, and layer thickness of 28.3 μm.
