The disclosure relates in some embodiments to hard coatings and weld overlays used to protect surfaces from wear and corrosion. The hardfacing process is a technique by which a hard metal alloy is deposited onto a surface which requires protection from wear. In some cases hardfacing materials are also subject to corrosive media, most commonly salt water.
An example of such an application is a pipeline which carries an abrasive slurry composed of a mixture of sands, rocks and saltwater. This application is common to the mining industry. The most common hardfacing materials belong to the family of chromium carbides. For the purposes of this disclosure, chromium carbide overlays are defined as any material which forms hypereutectic or hypoeutectic chromium carbides.
In these alloys, the large volume fraction of chromium carbides generates the wear resistance required of the hardfacing material. However, chromium carbides exhibit two negative effects: 1 they deplete the matrix of chromium and 2 they embrittle the microstructure.
Disclosed herein are embodiments of a work piece having at least a portion of its surface covered by a layer possessing a hardness of at least 50 Rockwell C and an elevated corrosion resistance as defined by a corrosion rate loss of less than about 6 mils per year in an aerated salt water environment 3. In some embodiments, the layer can exhibit a corrosion rate loss of less than about 3 mils per year in an aerated salt water environment 3. In some embodiments, the layer can comprise Fe and in wt.

In some embodiments, the alloy composition can be selected from group consisting of, in wt. In some embodiments of the compositions disclosed herein, the alloys may consist essentially of the percentage of the elements listed with the balance being iron.
In some embodiments, these compositions may comprise additional elements, such as nickel or other impurities, with the iron being the balance.
Disclosed herein are embodiments of a work piece having at least a portion of its surface covered by a layer comprising a microstructure comprising an Fe-based matrix comprising ferrite, austenite, martensite or a combination thereof, whereby the matrix contains a minimum of 8 wt.
In some embodiments, the matrix does not contain any iron or chromium containing carbide or borocarbide particles in excess of 5 microns in size. In some embodiments, the work piece can be a steel pipe and the layer coats at least a portion of an interior diameter of the pipe.
In some embodiments, the work piece can be a steel plate and the layer coats at least a portion of at least one surface of the steel plate. In some embodiments, the layer can be deposited using one or more of the following techniques: MIG welding, TIG welding, sub-arc welding, open-arc welding, PTA welding, laser cladding, or thermal spraying.
In some embodiments, the layer can comprise, in wt. In some embodiments, the layer or the feedstock material used to produce the layer can comprise in wt. Also disclosed herein are embodiments of a method of forming a coated work piece comprising depositing a layer on at least a portion of a surface of a work piece, wherein the deposited layer comprises a wear resistant and corrosion resistant alloy, wherein the alloy possesses the following thermodynamic traits a minimum weight fraction of chromium in an iron-based austenitic matrix phase calculated at K of at least 8 wt.
In some embodiments, the layer is deposited using one or more of the following techniques: MIG welding, TIG welding, sub-arc welding, open-arc welding, PTA welding, laser cladding, or thermal spraying.How to open local pdf file in webview in android
In some embodiments, the layer can comprise in wt. In some embodiments, the layer or the feedstock material used to produce the layer can comprise, in wt. Also disclosed herein are embodiments of a work piece having at least a portion of its surface covered by a layer, the layer comprising a high wear resistance as defined by an ASTM G65 mass loss of 0.
A hardfacing process is a technique which can be used to protect a surface from wear. Typical methods of hardfacing include the various methods of welding such as, for example, gas metal arc welding GMAWgas tungsten welding GTAWplasma transferred arc welding PTAlaser cladding, submerged arc welding, open arc welding, thermal spray, and explosive welding.
In some embodiments, it can be desirable for the hardfacing coating to be corrosion resistant as well. In some examples, increasing hardness through alloying control can be done at the expense of corrosion performance.
Chromium, as an example, is an alloying element well known to increase the corrosion performance of steels when it is in solid solution with the iron-based matrix, whether ferritic, austenitic, or martensitic. However, chromium preferentially reacts with carbon and boron, two alloying elements commonly used separately or together to increase the hardness and durability of hardfacing materials.
The formation of chromium carbides and chromium borides, effectively leeches the chromium from the iron matrix and reduces the corrosion performance of the material. Thus, there is a still a need for hardfacing alloys which also have high corrosion resistance.Oerlikon announced that it has signed an agreement to acquire Scoperta Inc.
