As the aerospace industry demands more from the materials it uses, the finishing of the surface becomes a greater part of the final product. 01 February 2010
Cold spray is one of the many names for describing a solid-state coating process that uses a high-speed gas jet to accelerate powder particles toward a substrate whereby metal particles plastically deform and consolidate upon impact. The term “cold spray” refers to the relatively low process temperature involved—which is typically much lower than the melting point of the spray material. 08 January 2010
Increasing demand for water and stringent new legislation to limit the discharge of effluent is taking place in many areas worldwide. Equipment innovations that reduce water usage and minimize the quantity of chemicals discharged into the environment as treated effluent and sludge have been installed in several state-of-the-art modern electroplating barrel machines that incorporate centrifuge post-treatment systems. The innovations will also supply attractive cost benefits by reducing drag-out. 09 December 2009
Investing in the business—and its people—pays big dividends for C.R. Hudgins Plating, a 60-year-old operation based in Lynchburg, Va. 19 August 2009
From electronics to aircraft parts, Master Metal Finishing of Patterson, N.J., finishes to spec—and beyond. 19 August 2009
For more than 80 years, the plating industry has been dependent on the use of various zincate and/or stannate solutions to assist in the plating of metals such as titanium, aluminum, and magnesium. It is becoming ever more difficult to use these solutions due to restrictive regulations—plus, they are difficult to work with. This article presents an environmentally acceptable and easy-to-work-with alternative process that does not require the metalizing of the metals to be plated or extensive cleaning and deoxidization procedures. 11 August 2009
Paramount Metal Finishing, a New Jersey-based finisher, leverages capabilities, expertise, flexibility, and problem solving to its advantage—and that of its customers. 18 December 2008
The use of volatile corrosion inhibitors (VCIs) within the metal finishing industry presents two generally unrecognized health and performance problems. VCIs have been used to prevent corrosion since World War II yet have had little risk analysis. Although many of the benefits of VCIs have been published, VCIs’ darker side is only now becoming known. 02 November 2004
