Stainless steel can corrode if free iron or aggressive chemicals compromise the chromium-oxide film. That’s where passivation comes in. This chemical treatment further improves the stainless steel’s corrosion resistance and extends its service life. What is Passivation? Passivation is a chemical surface treatment for stainless

Plating is considered one of the most used surface finishing processes in multiple industries. Metal plating is used to make the components corrosion resistant, improve solderability, increase hardness, reduce friction and improve paint adhesion. Plating not only offers longevity to the components but also gives

Electroplating of silver over other base material surfaces is known as silver plating. Electro-plating of silver has been used since the 1840s in order to make the component resistant to corrosion and make its appearance attractive. Silver plating provides remarkable properties to the surface of

Tumbling is a surface finishing method that removes burrs, smooths metal parts, and creates a uniform finish. The tumbling process is usually performed using centrifugal barrel finishing (CBF) for large batches of metals. The most remarkable thing that makes tumbling superior to grinding and polishing

Vibratory finishing is a mass finishing process that improves the surface finish of mechanical parts by removing burrs, sharp edges, rust, and other imperfections. The parts are placed in a vibrating container filled with abrasive media, water, and chemical compounds, where continuous movement polishes and

Sandblasting is a surface finishing process that uses high-pressure abrasive media to clean and smooth material surfaces. The impact of the abrasives removes contaminants, rust, paint, or burrs, and modifies the surface texture.. Its origin dates back to the 19th century; used to clear rusted

Copper plating uses an electrochemical or chemical process to deposit a thin layer of copper onto the surface of a prepared substrate, usually metal, but can also be plastic. Copper plating is generally not used directly for decoration or protective outer layer, but as a

Electroless nickel plating (ENP) is a technique to deposit a layer of nickel or its alloy on a substance through an autocatalytic chemical reduction reaction. Compared to electrolytic nickel plating, it does not require any external voltage source. The chemical nickel plating has made a
