Nadcap Accredited Chemical Processing

INTRODUCTION
Chemical processing services include citric-acid passivation, copper-sulphate testing, nitric-acid passivation and pre-penetrant etching. Nitric-acid passivation is a crucial process made post-fabrication to improve the corrosion resistance of a material such as stainless steel. The process itself consists of two steps, the first being to use acid to remove iron from the surface of the material and the second being to use an oxidiser to convert surface metal to an oxide form. This creates a layer that provides protection against outside corrosion. Pre-penetrant etching, also known as 'material smearing', refers to a non-destructive inspection process that lightly removes a very fine layer of the material in question to allow for inspection. The process includes adding either a caustic solution or an acid to a material to remove around 0.0025mm (0.0001”) to 0.005mm (0.0002”) of the surface layer. The inspector then evaluates the grain structure of the material for any problems that may have previously been masked.
