OPTIMALISASI VARIASI TEGANGAN DAN WAKTU TERHADAP KETEBALAN DAN ADHESIVITAS LAPISAN PADA PLAT BAJA KARBON RENDAH DENGAN PROSES ELECTROPLATING MENGGUNAKAN PELAPIS SENG
Abstract: This research
investigates the optimization of zinccoating by varying the voltage (2, 4, 6,
and 8 V) and time (10, 20, 30, and 40 minute), to find out the best plating
based of the thickness and adhesion. The chatode is mild steel by 30 mm in
length, 100 mm in width, and 2.5 mm in height. Electrolyte solution was composed
of sodium hydroxide
420 grams, zinc
oxide 97.5 grams, rochelle salt
9.75 grams, and
aquades 1 litre.
Measurement of coating thicknesses was using coating
thickness measuring instrument
dualscope MPOR and based
on ASTM B
499. Qualitative adhesion
testing of zing coating was based on ASTM B 571-97.The
best platingproperties, such as the deposit thickness and adhesion, is obtained
at 6 V and 20 minutes.
