What does photo etched mean?
What is an etching solution?
Acid etching is the process of applying hydrochloric/muriatic or buffered phosphoric acid to a slab, then rinsing it off with water. … Most coating manufacturers no longer recommend acid etching for a multitude of reasons.
Do you paint photo etched parts?
Photoetched parts can be painted using the same basic preparation that is used on a plastic part. Here is an endplate after being scuffed with a fine-grit sanding cloth. One of the nice things about photoetched parts is that they are metal, so any type of paint can be used on them.
What is the purpose of etching?
Etching is used to reveal the microstructure of the metal through selective chemical attack. It also removes the thin, highly deformed layer introduced during grinding and polishing. In alloys with more than one phase, etching creates contrast between different regions through differences in topography or reflectivity.
What is the etching process?
Etching is an intaglio printmaking process in which lines or areas are incised using acid into a metal plate in order to hold the ink. In etching, the plate can be made of iron, copper, or zinc. … The acid eats into the metal only in the exposed areas creating recesses that can retain ink.
