This citation summarizes a one-page announcement of technology available for utilization. Damaged sealing surfaces on aluminum castings used on spaceflight rocket engines have been experimentally repaired using stylus copper plating. A new approach using stylus nickel plating instead of the copper and cadmium plating has simplified the repair procedure and allowed the casting to be used in flight. The damaged sealing surfaces are stylus nickelplated in one step. The method may be easily incorporated into conventional aluminum-casting technology. This one-step repair can be considered for cost-aluminum automobile and aircraft engines to reduce the time and costs. ...FOR ADDITIONAL INFORMATION: Contact: The Patent Counsel, Marshall Space Flight Center, Alabama.
