Non-destructive material testing processes

Non-destructive material testing processes does not permanently alter the parts being inspected. This is a valuable technique to save time and money in product development, troubleshooting or research.

Etching processes for testing materials

Etch inspection shows you segregation and processing errors.

Process	For detection/ determination of:	For detection/ determination of:
Electrolytic etching of nickel-base materials	Segregation Grain size Machining errors	Within the following dimensions: approx. 1200 mm x 1000 mm x 1000 mm
Blue etch anodizing of titanium-base materials	Segregation Tool fracture Overheating Burnt spots	Within the following dimensions: approx. 1200 mm x 1000 mm x 1000 mm
Chemical etching of titanium-base materials, nickel-base materials and steels	Segregation Grain size Machining errors	Within the following dimensions: approx. 1200 mm x 1000 mm x 1000 mm
Local etching of all materials	Segregation Grain size Machining errors	Manual, within the following dimensions: approx. 1200 mm x 1000 mm x 1000 mm
