What is surface treatment and how does it work? Read

Treatment of surfaces of bio-medical testing devices to improve wettability of surfaces for confluent liquid flow. Treatment of syringe barrels prior to printing. Treatment of the inner surface of needle hubs prior to bonding a stainless steel needle. Treatment of electronic cable What is Passivation? How Does Stainless Passivation Work?Stainless steel derives its corrosion-resistant properties from the chromium content. Chromium, when exposed to oxygen (air), forms a thin film of chromium oxide that covers the stainless steel surface and protects the underlying iron from rusting. The purpose of passivation is to augment and optimize formation of the chromium oxide layer.Surface Treatment Methods and Effects on Stainless Steel PipesSurface Treatment Methods and Effects on Stainless Steel Pipes Overview.
