US Patent for Apparatus for depleted chemical milling

A process is disclosed for removing heavy metals, dissolved aluminum, sulfides and organic compounds from a caustic etch solution, thereby regenerating the etching power of the solution or facilitating its disposal into the environment. The process consists of forming a first filtrate from which heavy metals present in the solution have been removed, and a second filtrate obtained by

Caustic Etch Regeneration P2 InfoHouse

2018-6-13  698 Caustic Etch Regeneration System. At that time, five systems were installed in different facilities around the country. The early systems were installed at a time when caustic was less expensive and the environmental pressures were not so severe. Today, however, the price of caustic is up, as is the value of the trihydrate by-product.

Chemical Milling an overview ScienceDirect Topics

Chemical milling process is generally carried out in a series of five steps: cleaning, masking, scribing, etching, and demasking [10]. Fig. 5.1.4 represents the schematic diagram of chemical milling process. At first, the workpiece surface is cleaned properly for removing the contaminants which could negatively impact the quality of the finished part.

Alternatives to Hydrofluoric Acid Etching At Wyman

2010-4-29  The current procedure that Wyman-Gordon uses is based around large chemical etch tanks into which all the parts are dipped. The parts are first blasted with steel shot to remove the scale and then the chemical etch is used to remove the alpha case. The chemical composition of these etch tanks are hydrofluoric acid and nitric acid in water.
