Pre-Penetrant Etch uses either acid or caustic solutions to remove 0.0001″ to 0.0004″ of material from the parts’ surface. DCI offers immersion or swab etching. Material smearing can have a detrimental effect on Liquid Penetrant Inspection as defects that are normally open to the surface can be partially or completely covered over. DCI’s etch line includes tanks for etching of titanium, aluminum, stainless steel, Inconell and other nickel-based alloys.
