Pengaruh Waktu Electroplating dengan Chrom Pada Baja Karbon Rendah Terhadap Kekerasan, laju Korosi dan Tebal Lapisan

Abstract

Electrically plating or electroplating is one method used to beautify looks fine and also to improve the mechanical properties of the metal. The teksperiment is performed by preparing specimens have been measured with different variations in time for electroplating with a current of 10 amperes at 12 Volts. The results show that the corrosion test specimen electroplating results with the arrest of 0.1889847379 mpy 40 minutes, 30 minutes of 0.1771731918 mpy, 20 minutes by 0.1417385534 mpy, and without coating 0.93298832 mpy. Judging from the results on each specimen corrossion the safest coating coatings with detention is 20 minutes and is the fastest corroded specimens without coating. Hardware test results from each specimen tested showed rising violence in the area coated by electroplating. The test results showed a thick layer on the detention of 40 minutes is the result of sedimentary layers thicker than the initial 30 minutes and 20 minutes.
