✦ Synopsis

A large investment to increase electroless nickel production has been made recently in Gloucester, UK by Poeton Industries. They are taking this opportunity to question the validity of current test methods for corrosion resistance.

Much of the performance data for nickel solutions is based on a British Standard (BS EN ISO 1462:1995) that grades the number of rust spots per square inch on the surface of the coating after accelerated exposure during a standard salt spray test. This has led to typical claims of 1000 h corrosion resistance for most nickel coatings.

However, Poeton's experience over several years appears to contradict this claim. Salt spray testing by the company shows that many materials rated to 1000 h would in fact show signs of corrosion after 40-50 h. The company is recommending that to maintain the confidence of the engineering community, the metal finishing industry needs to review its standards.
