Enhancement Surface Coating Stainless Steel And Copper Using Ultrasonic Batch

Abstract

Electrodeposition is considered an easy and cost effective technique for the manufacture of alloy layers. Various properties for coatings can be achieved by selecting various electrodeposition parameters. These materials have the advantage of corrosion resistance but relatively expensive. They will need alternative materials that can easily obtained and replace these materials. This paper discusses the process of coating stainless steel AISI 304 and copper with Ni. Electric current and coating time is used in the electroplating coating process of Ni to Ni thickness supported by ultrasonic batch. AISI 304 stainless steel and copper coated using nickel (Ni) with variable time and fixed electric current parameters. The electric current used 1.5 ampere, the time of plating process of 60 seconds, 120 seconds, and 180 seconds. The composition of nickel electrolyte solutions using nickel sulfate 300 gr/L, nickel chloride 30 gr/L, and sour borax 30 gr/L with brighteners added one (I) 15 mL and brighteners two (II) 1 mL. Measurement of thickness is done by using optical microscope assisted by imageraster software. The best process used 1.5 amperes of electric current and time of 180 seconds. The value of copper thickness is 26.50 (μm) using ultrasonic batch.

Improved performance of corrugated metal gaskets in boiler’s piping system through multilayered coating

“…According to both papers, copper or nickel coating reduces material corrosion. An AISI304 stainless steel coating experiment with nickel-coated copper used a time variable and a fixed electric current parameter to conduct [11]. The stainless-steel material was effectively copper coated, with the greatest results obtained at a current of 1.5 A and a time of 180 seconds.…”
