【国外标准】 Standard Practice for Preparation of Tungsten and Tungsten Alloys for Electroplating

This practice contains two recommendations based on several reported practices for the process selection in electroplating on tungsten and tungsten alloys. Surfaces should be cleaned either by descaling, solvent cleaning, or alkaline soak cleaning before electroplating. Evaluating which of the suggested processes to use is dependent on the application of the produced coating.1.1 This practice makes recommendations of several reported practices for electroplating on tungsten and its alloys along with comments as a guide in the selection of a processing method for a given application. Because data on methods and results of evaluation with electroplated coatings on tungsten are limited, a recommendation of one method over another cannot be made.1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
