Chemical etching or chemical milling can help reveal hidden abnormalities or defects such as cracks, laps or corrosion in a material or component. Our trusted experts have experience with different types of chemical etching, including aluminium 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.
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. We provide chemical etching as a standalone method and as preparation for a range of test types and inspection techniques.
Chemical Etching for Cost Efficiency
Identifying material imperfections before submitting the sample to nondestructive testing, mechanical testing, metallography, microscopy or other analytical techniques can help save time and cost for manufacturers.
Our experienced experts provide etching and other chemical processing services for a number of industries, including aerospace, defense, transportation and power generation. For more information about our chemical etching services or to request a quote, contact us today.
