ABSTRACT:
The surfaces of aluminum and aluminum alloy articles, when abraded with a low-density abrasive product in the presence of a lower alcohol such as isopropanol, are readily plated or coated to provide a uniform plating or coating. The process is particularly useful in providing aluminum-silicon brazing alloy with nickel or nickel-lead plating for brazing.
