The Present Position of Bright Nickel Plating in England

The selection of a pretreatment and conversion coating cycle for any application is subject to many considerations, including anticipated environmental service conditions, life of finished article, type of finish to be applied, condition of metal surface prior to pretreatment, design of article to be treated, throughput required, space and/or equipment available, capital costs, operational and maintenance costs. The characteristics of various types of pretreatments and conversion coatings for ferrous and non ferrous metals are discussed in relationship to the above considerations. It is suggested that the final selection will be on economic grounds from processes of adequate technical merit but subject to any site limitations.
