ÌìÃÀ´«Ã½'s chemical etching (or chemical milling etching) can help reveal hidden abnormalities or defects such as cracks, laps or corrosion in a material or component.

What is chemical etching? 

Chemical etching is a form of processing that uses acids, bases or other chemicals to remove layers of a material or clean unwanted substances from a part or test sample. 

 

Chemical etching services 

ÌìÃÀ´«Ã½ provides chemical etching as a standalone method and as preparation for a range of test types and inspection techniques. 

Our trusted experts have experience with different types of advanced chemical etching, including aluminum cleaning etch, anodic etch, blue etch anodize (BEA), nital etch and pre-penetrants etch. We also offer the chemical etching of nickel parts (nickel etch) and materials to perform material segregation and defect inspection.

 

Advantages of chemical etching 

Identifying material imperfections before submitting the sample to non-destructive testing (NDT), mechanical testing, metallography, microscopy or other analytical techniques can help save time and cost for manufacturers.

 

The ÌìÃÀ´«Ã½ advantage 

Our experienced experts provide etching and other chemical processing services for a number of industries, including aerospace, defense, transportation and power generation.
