Coventya (Brooklyn Heights, Ohio) now offers the Tristar 330 AF Process, its next-generation sulfate-based chromium decorative plating process for Coventya’s Tristar Trivalent Decorative Chrome Technologies line. Coventya says this new process outperforms present state-of-the-art technology while providing a deposit color similar to hexavalent chrome deposits.

Coventya designed the process components for effectiveness over a broad concentration range. A high rate of deposition allows the process to reach the required deposit thickness of 0.2 - 0.4 µm in 4 - 5 minutes at cathode current density ranges between 80 - 100 A/ft2 (861 – 1,076 A/m2).

The company says its Tristar 330 AF Process, in combination with its Tristar Shield Cr VI-free post-treatment process, results in a deposit corrosion resistance that satisfies the most demanding specifications for CASS and Neutral Salt Spray tests for steel and plastic parts, including sanitary-plumbing fitting components.

    Masking is employed in most any metal finishing operation where only a specifically defined area of the surface of a part must be exposed to a process. Conversely, masking may be employed on a surface where treatment is either not required or must be avoided. This article covers the many aspects of masking for metal finishing, including applications, methods and the various types of masking employed.
