Electrochemical etching is often incorrectly referred to as "acid etching" - however unlike "acid etching" - electrochemical electrolytes are not caustic and will not cause harm through incidental skin contact. That way, the creator can explain what she/he meant. The Magic of Electro-Chemical Etching. It is an austenitic alloy that includes chromium and nickel and is lower in carbon than the standard 304 grade of stainless. In about 10 minutes or so the pattern was etched into the blade. I then used salt water and a DC power supply (kind of like a battery charger but fully adjustable) to etch through the steel. its rea… Mods please feel free to move it if it should in fact have been posted elsewhere!

Any time you have a question about a specific project, it's best to use the "Ask a Question" feature that is below each project. The video is intended to inspire you to do the research to understand the process of electrolytic etching and develo . source/image(PrtSc): ADDYOLOGY Report this item. Laser fused, wide flange, 304L stainless steel beams have been used as a corrosion resistant building material in Immersion etching at 20 degrees Celsius: For etching duplex and 300 series stainless steels. It is a cool example of a redox reaction, and way more fun that a canned chemistry lab. For Etching 304 stainless steel etching use ferric chloride solid 1 kg with one liter of water and the solution to be kept idle for min. When etching steel, use the same recipe for the Saline Sulfate Etch as given above. Materials: Metal Water Bottle, either stainless steel or aluminum That said, I set out to find a method that would work on stainless steel. I have also seen deep etchings made with a mask and sand blasting. I have done lots of glass and slate etching using glass etching cream, but through my research I found that it will not work for etching stainless steel. Etched stainless steel? Mix it with a 1:1 ratio of common table salt to prevent a fine layer of copper sulfate from coating the metal and preventing proper etching. This step is useful if there will be a second stage of resists applied to the metal. Electric Etching…Minor amounts of fairly crude electric etching can use salt water and a 9-volt battery. Basically you just apply a resist to the metal you want to etch, and this will become the anode +. 189 42.1K . You don't need much power, only a few volts and ~500ma for a fast etch. You just need to make sure that the … Here's the one I … I wasnt sure where to put this...but since its really one of the last steps you will take when making a blade, I decided this would be a good place. Electrolyte is simply used to aid the flow of low-voltage electric charge through the gaps in the stencil. Custom belt buckle using a salt water etch. So i wanted something easier. Here are two more made for @lyshyxoxo and her daughter. It doesn't matter why, let just say its a terrible process and logs don't appreciate the work. Enter salt water etching. Keep any connection to a wall outlet or extension cord away from your container of salt water. Parts are able to be fully processed in a shorter turnaround time than other procedures, and often do not require secondary finishing. Capacity – Brushed Stainless Elenco TL-6 Alligator Lead Set, 10-Piece, 14 inches (2) Water Bottle Holders W/ Blue Aluminum Carabiner Attachments Directions Ferric chloride – Works best on copper, brass, and nickel silver, and stainless steel. Copper sulfate is used to etch mild steels rather than stainless steel. A resist is applied to the metal, then the metal is dipped into the acid until the desired effect is achieved. It is best mixed in a 1 to 1 ratio with sodium chloride (NaCl - common table salt) to keep the copper sulfate from coating the steel with a deposit of copper that will stop the etching process. More by the author: Make a "cheap" power supply for etching metals with salt water. The etching process also produces a tiny amount of hydrogen (a harmless but flammable gas), and you should provide ventilation to prevent any accumulation. Stainless steel etching using chemical milling or acid etching is a popular alternative to other forms of metal fabrication such as stamping, laser marking or water-jet cutting, as it uses minimal mechanical processes and it cost-effective. 08/18/17. 2: CuCl2 Hydrochloric acid Ethanol: 5 grams 100 ml 100 ml: Immersion or swabbing etch at 20 degrees Celsius: For etching duplex and 400 series stainless steels and Ni-Cu alloys and superalloys. Did this once on a stainless steel knife blade. Nov 11, 2008 #2. galadduin. Salt water etching of stainless steel Superior Etchworx. The red wire is wrapped around the qtip cotton. The blue solution gradually fades as the etching progresses and turns colorless when it's finished. Introduction: Power Supply for Etching With Salt Water . The Copper Sulfate is mixed in a one to one ration with sodium chloride (salt). To analyze the structure and grain size of 316 stainless steel, we have used Aqua Regia, that means: 30 ml of distillated water, 20 ml HCl and 15 ml HNO3. 1-Placed scotch tape on blade. Is there something around the house or local stores that will, like vinegar or something? Whilst the list looks long, the items are easily available from the supermarket / eBay.

I use a combination of chloride, sulphate and phosphate salts. Saved by Judy York. Gather up the materials you need. The acid will slowly eat away layers of the metal, and it will flake off leaving exposed areas that create a design. Copper sulfate – Best for mild steels. Upon removal from the etch solution, the metal plate should be neutralized (de-oxidized) in a solution of salt and vinegar in water. You would then put the workpiece into the pot, along with the salt water, and etch right in the pot. Copper sulphate is a blue solution and will gradually fade to a transparent colorless liquid as the etching process takes place. 4- Hooked battery to blade and other into the salt water. Once a plate has been etched to the required depth and rinsed it is crucial to blot off any remaining dampness with paper towels and then speed dry plates otherwise the steel surface will quickly rust. Over and over again I came across a method using salt, water and a 9 volt battery. Drying with hot air from a blow dryer further minimizes oxidation. Mix with water at a 1:1 ratio. Experiment: Once you have gathered the supplies, the experiment should take 30-45 minutes, depending on the intricacy of the design. It worked amazingly well. Although the belt buckle was wrapped in duct tape, the vinegar-salt solution leaked through, which resulted in slight etching on the inside on the buckle. The accelerant is a tetrahydroglyoxaline compound. Instead of a sacrificial piece of metal, you could use a stainless steel pot and put the negative (-) alligator clip right on the rim of the pot. Add Tip Ask Question Comment Download. The name was cut from vinyl and attached to the steel buckle blank. Dec 25, 2004. I use a ratio of 1 part s., 1 part v. to 6 parts water. 115.
