All of our black oxide processes mesh with manufacturing production and easily integrate in-house, cutting lead times, increasing productivity, and saving on finishing costs.
We have pre-engineered finishing lines to make implementation fast and easy with a mini-system , 40 gallon line , gallon line , CNC Automated line , and provide conversions or upgrades to existing lines. Our Liquid and Gel Black Oxide products are ideal for swabbing or brush-on applications for metal touch-ups for machined components, in-place finishing for architecture applications, and artistic or sculpture metal working.
The LUMICLAD process is the first and only high quality method for blackening aluminum that doesn't involve the complexities and high costs of electrolytic black anodizing. The kit comes complete with seven 5-gallon immersion tanks, covers, immersion heater and a generous supply of LUMICLAD chemical products to operate the entire process for months, depending on workloads.
Occupying only about 20 square feet, the mini BK-LC Line fits well almost anywhere in the plant, such as in the tool room, prototype or maintenance area or in a manufacturing cell. It is especially useful in job shops where short run blackening is often needed on a "rush" basis. Want more information? Call for Free Brochure. See online at www. The elevated temperature is the catalyst needed for the chemical reaction to occur. Black oxide penetrates the metal and creates a coating 10 millionths of an inch above and below the surface.
No hydrogen embrittlement occurs during this step because the parts are not exposed to an acid activator. The final step in the black oxide process is applying a supplementary coating to the part. Black oxide coatings by themselves are easily corroded, resulting in flash rusting. This final finish is necessary to provide corrosion protection to the part.
The type of final finish applied determines the type of color the part will receive. Warming the solution to about degrees Fahrenheit will improve the desmut results. Mix one part sulfuric acid with one part distilled water in the other tub. Add the water first, then slowly add the acid. You should mix enough to fully submerge the piece you wish to anodize. Attach the negative cathode from the power supply to an aluminum plate.
Submerge the plate into the acid solution. Connect the positive lead from the power supply to the aluminum piece you want to anodize using a length of aluminum wire. Place the piece of aluminum into the acid bath solution. Turn on the power supply to 12 volts DC at two amps.
Monitor the cathodes for bubbles forming in the acid solution.
