摘要：
A multi-layer film for use in forming a layer of hardfacing on a surface of a tool includes a first layer and a second layer covering at least a portion of a surface of the first layer. The layers each include a polymer material and a plurality of particles dispersed throughout the polymer material. An intermediate structure includes a body of an earth-boring tool, a first material layer disposed over a surface of the body, and a second material layer disposed over the first material layer. A method of applying hardfacing includes providing a first material layer on a surface of a body of an earth-boring tool, providing a second material layer adjacent the first material layer, heating the body and removing the polymer material from the body of the earth-boring tool, and heating the body higher temperature to form a layer of hardfacing material.
