When considering proper pre and post cleaning of parts, quality is just one consideration for captive heat treaters and commercial shops. The other is the damage that both vacuum and atmospheric furnaces can incur, leaving shops with costly problems to their equipment including: loss of vacuum, contamination to future runs, smoke bombs and shortened quench… Read more »

Bob’s Brain: A Review of Functional and Decorative Black Oxide Coatings
Black oxide is the conversion of a base metal material to an oxide of that base metal material. A prime example would be Fe3O4, which is black iron oxide, otherwise known as magnetite; another is a CuO, or copper monoxide. It occurs when the chemicals react with a base material to form an oxide of… Read more »
5 Steps to Adding Electropolishing
Surveys show that only 25% of all metal finishing operations in North America offer electropolishing to their customers. With a possible rise in the need for electropolishing thanks to reshoring efforts for medical parts and equipment, demand could outpace availability as manufacturers seek to find finishers to electropolish those parts to a high specificity. Fortunately,… Read more »
