The resiliently coated metallic finger seal described herein is formed of two metallic seal members being fixed together at one end with fingers projecting rearwardly therefrom. The fingers on each member are offset so that the slits of each metallic seal member are not aligned. The fingers of the two members are then encapsulated by a resilient coating material, such as a room temperature vulcanizing silicone rubber. The seal means is described as annular and can be constructed of one piece or a plurality of sections. In constructing the seal means the metallic seal members are cleaned, primed where it is desired to have the resilient coat permanently affixed, and the resilient coat is then applied. The resilient coat does not cover the entire fingers so that the proper flexibility at the hinge location will reamin. After curing of the resilient coating material a heat reflecting and lubricating material is placed thereon.

A method for fixing an abradable material of random interlocked metallic fibers sintered and pressed to a specified thickness and density in place on a substrate is set forth where the abradable material bonded to a metal backing plate is placed with the metal backing plate engaging a substrate. The abradable material is compressed without heat to substantially a solid mass at spaced spots; the compressed spots are heated by electrical resistance to a sintering temperature and pressed to form a solid mass. The solid mass of each spot of abradable material is heated to an increased temperature by electrical resistance, welding the solid mass of abradable material to the substrate by completely penetrating the backing plate and forming a weld nugget.
