Embodiment Construction

[0011] figure 1 An exemplary wear device 20 is described, which may be provided alone or in combination with other components for enhanced wear resistance against a variety of different wear mechanisms. In this case, the abradable device 20 comprises an abradable layer 22 (e.g., a coating) comprising a matrix 24, particles 26 dispersed throughout the matrix 24, and a portion distributed over the matrix 24. The boron material 28 in (shown as shaded).

[0012] The boron material 28 provides the advantage of stiffening the matrix 24 for increased wear resistance and thus helps retain the particles 26 in the matrix 24 . As one example, the abradable device 20 includes an outer surface 30 that is subject to abrasive conditions. In the absence of boron material 28 , matrix material 24 may wear away and gradually expose particles 26 such that particles 26 become loose or detach from matrix 24 . Once dislodged, the particles act as abrasive particles and accelerate wear. However, ...

Abstract

The invention relates to a wear resistant device which includes a substrate of a first metallic material and a wear resistant layer disposed on the substrate. The wear resistant layer includes a matrix of a second, different metallic material, particulates dispersed throughout the matrix, and a boron material dispersed within a portion of the matrix.

Description

Background technique [0001] The present invention relates to materials and compositions for enhanced wear resistance. [0002] Drill surfaces and shafts etc. may contain surfaces that are subject to abrasive conditions. Depending on the material, the surface can be directly hardened using a carburizing or nitriding process to improve the wear resistance of the surface. In some cases, the surface is alternatively plated with chrome to provide a greater degree of wear resistance. [0003] Recently, there is a need to replace chromium. However, potential alternative materials have not been successful in providing the same degree of wear resistance as chrome plating. Furthermore, such materials do not exhibit a broad range of wear resistance against different types of wear mechanisms such as those associated with hard particles, with mating components and with elevated temperatures. Contents of the invention [0004] An exemplary wear-resistant device includes a substrate of...
