Abstract

The durability of decorative nickel-iron coatings in various types of exposure is discussed in detail. It has been determined that these coatings, as part of a specific multiple deposit system, perform acceptably for exterior automotive applications. It is necessary that a microdiscontinuous chromium be present in the composite coating to achieve optimum results and it is desirable to use a copper underlayer to the nickel-iron electrodeposits. Corrosion test results are also reported which establish that static tests cannot be relied upon to predict actual mobile service performance.
