Troubleshooting decorative electroplating installations, part 5: plating problems caused by heat & bath temperature fluctuations

摘要

In previous parts of this series, emphasis was given to troubleshooting of the sequences for pre-plating and electroplating over metals, Parts 1 and 2; the causes, symptoms and troubleshooting for pores, pits, stains, blistering and "spotting-out" phenomena, Part 3; and troubleshooting plating on plastic systems, Part 4. Here in Part 5, causes and some typical examples of problems that occur in electroplating as a result of a) thermal, mechanical surface treatments, b) the metallurgy of the part to be plated or c) effects of plating bath temperature on plating variables and quality of the deposits are discussed.
