Plasma Chemical Etching Process, Sputter Etching Process
The chemical dry etching process is usually isotropic and exhibits high selectively. Anisotropic dry etching has the ability to etch with finer resolution and higher aspect ratio than isotropic etching. Due to the directional nature of dry etching, undercutting can be avoided. The reactive chemical species are free radicals, which is neutral ...

Chemical Etching
An effective chemical etching process, therefore, requires a close control of the solution composition, temperature, and mass transport. Adequate stirring (e.g., by spraying or by part motion) is necessary to ensure the supply of fresh solution at the surface and to maintain uniformity of temperature of the solution and the workpiece.

Electrochemical Etching
Electrochemical etching can take place without complete dissolution of anode material in the etchant. In this case, an oxide layer grows on the surface. This is anodization that is widely used for the modification of titanium implant surfaces [45–47].In Ref. [46], microphotographs of the Ti alloy surface are given after anodization in aqueous sulfuric acid (Fig. 2.2.13).

Chemical Etching Process: A Step By Step Guide
Chemical etching is a process which involves the use of chemicals by well-trained experts to etch various non-required parts of metals from a great shape metal. The desired shape is stored in the system and then photo-pasted on the metal sheet. The non-critical part is removed from the sheet to ensure that the final product meets the requirements.

It is also dependent on material thickness. For metals 0.01 mm to 0.25 mm in thickness, the minimum standard etching tolerance is ±0.025 mm. For thicknesses above this (to a maximum of 1.5mm) the minimum standard etching tolerance is typically ±10% metal thickness. While traditional metal machining can achieve tighter tolerances, there are ...
