ABSTRACT:
Methods are provided for bonding pure rhenium to a substrate comprising a material. Non-lubricated components configured to have friction contact with another component are also provided. In an embodiment, by way of example only, a method includes disposing a eutectic alloy over the substrate to form an inter layer, the eutectic alloy comprised essentially of a base alloy and one or more melting point depressants and having a melting temperature that is lower than a melting temperature of the substrate material and a melting temperature of rhenium, placing pure rhenium over the inter layer, and heating the inter layer to a temperature that is substantially equal to or greater than the melting temperature of the eutectic alloy, but that is below the melting temperature of the substrate material and the melting temperature of the pure rhenium to bond the pure rhenium to the substrate.
