Abstract: A method for repairing turbine engine seals and a product manufactured in accordance with the method are provided. A worn or damaged honeycomb seal is removed from a backing plate together with a portion of the surface of the plate. The plate is restored to substantially its original thickness by a low pressure plasma spraying operation which may be followed by further machining to arrive at the required plate thickness. A new seal is then brazed thereon. The finished product will include the backing plate, a low pressure plasma sprayed coated surface, and a honeycomb seal brazed to the coated surface.

Abstract: A method for reducing the amount of free vinylidene chloride in an aqueous dispersion of a vinylidene chloride polymer by adding to the dispersion a small amount of a redox initiator, and then subjecting the dispersion to a temperature in the range of room temperature to about 40.degree. C. for a period of at least one hour. Substrates such as packaging films can be coated with the aqueous dispersion, or with a solvent solution of the polymer after separation from the dispersion. By use of such a coating bath, the amount of vinylidene chloride vapor in the atmosphere near the coating station is significantly less than the amount when using a coating bath of polymer not subjected to the method of the invention.
