Because of its face center cubic (fcc) structure, aluminum readily mixes with other metals in the liquid state; however, the solid solubility of various metals is limited to a few percent.
The question sometimes arises of whether the sulfuric acid anodizing bath is made up of volume or by the weight of sulfuric acid.
Fabrication of aerospace structures requires rigorous standards due to the high cost of rework and the severe consequences of in-flight failure.
Adtec II and Veterans Metal have announced a strategic alliance aimed at increasing production opportunities for manufacturing companies.
The metallurgy of 7000 series aluminum alloys is presented as it relates to the base metal surface, the interface from which the anodic aluminum oxide (AAO) grows.
When making up a brand-new sulfuric acid anodizing bath (Type II & Type III), it is important to have at least a small amount of dissolved aluminum in the bath to act as a buffer to help prevent the burning of the parts.
Abrasion resistance of anodized aluminum is an important property that is often required for material performance and quality control.
Business has probably never been better for owner Scott Penner’s Automatic Anodizing.
The purpose of the salt spray test is to validate the “health” of an anodize process line.
All Metals Processing of Orange County in Stanton, California, has obtained approval to process Boeing BMS 10-85 Aluminum Pigmented Coating and NAS 4006 coating.
For decades industry has used aluminum in the development and fabrication of a wide variety of products and finished goods.
A protective oxide film of aluminum is only stable in a pH range of 4.5 to 8.5.1 Chemical operations for the metal surface of aluminum include many process solutions that intentionally exceed this pH range for cleaning, metal removal, and subsequent smut removal.
Getting current efficiently to the anodizing tank is a must for all anodizing operations.
Numerous metals are subjected to anodic oxidation. As a result, one can obtain amorphous barrier-type oxides, crystalline barrier-type oxides or amorphous nanoporous oxides.
An explosion at Quick Turn Anodizing and Black Oxide Coatings in Guthrie, Kentucky Jan. 18 killed one person and injured four others.
Surface Finishing that makes use of tanklines should consider the use of rinsing alternatives when in design or as an effort for process improvement.
Die castings pose some of the most challenging problems in anodizing.
