| dc.description.abstract | SS400 is structural steel, which is categorized within low carbon steel. It
could not be hardened by heat treatment. In order to increase its
properties, SS400 is enhanced with surface treatment and surface plating.
Chrome is an element added as an alloy or as a coating to increase the
corrosion resistance of steel. It also improved the surface appearance by
shining the surface of the steel. This research aims to develop the surface
properties of SS400 using chrome by electroplating. The quality of the
surface improvement was evaluated by adhesive strength using a PosiTest
AT-M Adhesion tester according to ASTM D4541 standard. There are
three parameters with three-level each: i.e. voltage (3 volts, 6 volts, and 9
volts), temperature (45 ℃, 50 ℃, and 55 ℃), and time (20 minutes, 25
minutes, and 30 minutes). Combination of parameters and levels
according to the Taguchi orthogonal array L9(33
) with thrice replication
each. Minitab 18 was employed to analyze the S/N ratio and ANOVA.
The results showed that the voltage, time, and temperature significantly
contribute to the adhesiveness at the level of 51.18%, 39.7% and 7.25%,
respectively. The maximum adhesiveness value of 22.11 MPa was
achieved using a combination of the voltage of 9 volts, the temperature of
55 ℃, and the time of 25 minutes. | en_US |
