Method of manufacturing a metal and polymeric composite article

A method of manufacturing a metal and polymeric composite valve seat insert comprising the steps of:

• applying a spray deposited metal layer on to a cylindrical tube-shaped carrier;
• applying a spray deposited polymeric material onto said carrier, to form said article;
• and
• removing said article from said carrier.

A method of manufacturing a metal and polymeric composite article comprising the steps of:

• applying a first layer of spray deposited metal atop a carrier;
• applying a second layer of spray deposited polymeric material atop said first layer;
• and
• applying a third layer of spray deposited metal atop said second layer, said third layer encasing said second layer and forming said composite article.

A method of manufacturing an internal combustion valve seat insert comprising the steps of:

• applying a spray deposited metal layer on to a tubular carrier;
• applying a spray deposited polymeric material onto said carrier, said polymer material partially covering said metal layer;
• and
• applying additional spray deposited metal layers atop said polymer material, said additional spray deposited metal layers interconnecting with said spray deposited metal layer to form a metal and polymeric composite having polymeric material trapped between interconnected areas of solidified metal.
