Surface Textures and Process Characteristics of the Electrolytic Photoetching of Annealed AISI 304 Stainless Steel in Hydrochloric Acid
Summer 1984
Results forming part of a general investlgation into quantitative
aspects of photoetching are presented here. This
manufacturing process, also known as photochemical machinlng
(pcm) is a multi-stage process employing photographic
and chemical etching techniques for the production
of components and devices in a wide range of
metals and alloys.
Stainless steels are of particular importance in production
engineering and may be spray etched through
photoresist stencils with modified aqueous ferric chloride
solutions. The resultant surface finlsh and edged profiles
have now been studied in detail.
