Chemical etching is an etching method that uses a high-pressure chemical syringe to remove material and create a permanently etched image on the metal. A mask or resistor is applied to the material surface and selectively removed by exposing the metal to create the desired image. A conditioning machine benefits from the corrosive reaction between the chemical and the material and amplifies the effect by heating the solution and spraying it at high pressure. The chemical syringe dissolves unprotected metal areas to etch atom-by-atom material for a smooth, burr-free finish.
How chemical etching process is done
Chemical etching is done in a series of steps
The desired material, substrate, is laminated with a photosensitive resist. It is then exposed to a UV light to get a positive product’s image. This product is obtained after exposing the substrate to a solution that gets rid of the unprotected parts from the substrate. These steps are done carefully to ensure the best results are achieved.
What metal that can be chemically etched?
Most metals can be produced with the right equipment.
Stainless steel, brass, copper, bronze, aluminum, titanium, nitinol, molybdenum, zinc, nickel, silver, gold, magnesium, Silver, nickel, Phosphorous bronze, Beryllium copper, Mu Metal
Benefits of chemical etching
Hard chemically tested tools have many advantages, such as cutting and dying. It provides the flexibility of good and inexpensive design. The compression process does not cause mechanical stress on the material, leaving particles and tensions unchanged in the material structure or magnetic properties.
In this, there is no use of expensive equipment like laser reflections or cuts due to mechanical improvisation or heat loss. Chemical abstraction is capable of processing very thin materials that are suitable for all types of metals and that can be difficult to use with other methods.
• Repeat for higher production.
• Great flexibility in design, and inexpensive equipment.
• Asymmetrical and compact parts.
• The physical characteristics and grain structure remain unchanged.
• Strict durability is capable of producing components with complex geometry.
• Another major benefit of producing medical parts by chemical etching lies in the fact that the same process route is used to prototypes as is used to produce volume quantities.
Applications of chemical etching in medicine
Stainless steel utilized in medical is composed of three metals nickel that gives an even finish, chromium gives its corrosion-resistant properties, and molybdenum increases the hardness to sustain the cutting edge.
Titanium-due to its ability to resist corrosion, biocompatibility and the ability to knit with human bones, it has become a basic material in the medical field. has become a fundamental material used in medicine. Titanium and its alloys are used in a variety of implant applications, including bone and joint replacement, maxillofacial and craniofacial treatments, and cardiovascular devices, as well as for external prostheses, and surgical instruments.
Nickel Titanium, is a metal with two unique properties, that have made many new medical innovations possible: shape memory and super-elasticity characteristics.
Cobalt-Chromium due to its resistance to wear and corrosion it is applied in orthopedic implants.
