Abstract:
Embodiments of an iron-based coating configured to be thermally sprayed are disclosed. The iron-based coatings can be generally non-magnetic, thus allowing for thickness measurements to be performed on the coating with standard magnetic measuring equipment. Further, the iron-based coating can have advantageous properties, such as high hardness, high wear resistance, and high adhesion strength.
Abstract:
A class of nickel based alloys having a fine grain structure resistant to stress corrosion cracking, and methods of alloy design to produce further alloys within the class are presented. The alloys act as suitable welding materials in similar applications to that of Alloy 622. The line-grained structure of these novel alloys may also be advantageous for other reasons as well such as wear, impact, abrasion, corrosion, etc. These alloys have similar phases to Alloy 622 in that they are composed primarily of austenitie nickel, however the phase morphology is a much finer grained structure opposed to the long dendritic grains common to Alloy 622 when it is subject to cooling rates from a liquid state inherent to the welding process.
Abstract:
A substrate coating technology for coating a substrate with a coating material having a substantially similar base composition as the material composing the substrate is disclosed. The chemical composition of the coating material is selected to have a melting temperature lower than the melting temperature of the substrate such that the coating material exhibits deep eutectic properties when compared to the substrate. The chemical composition allows the molten coating material to be applied to the substrate by dipping the substrate or pouring onto the substrate.
Abstract:
Disclosed herein are embodiments of hardfacing/hardbanding materials, alloys, or powder compositions that can have low chromium content or be chromium free. In some embodiments, the alloys can contain transition metal borides and borocarbides with a particular metallic component weight percentage. The disclosed alloys can have high hardness and ASTM G65 performance, making them advantageous for hardfacing/hardbanding applications.
Abstract:
Embodiments of wear resistant ferrous alloys are disclosed herein. In some embodiments, ferrous alloys can have a matrix which includes near spherical and hypereutectic borides and/or borocarbides while at the same time avoiding the formation of rod-like borides and/or borocarbides. In some embodiments, the wear resistant ferrous alloys can be used as a coating, such as a hardfacing layer, to add protection to different components.
