COBALT & NICKEL Based Hardfacing Alloys COBALT & NICKEL Based Hardfacing Alloys Stoody.com COBALT & NICKEL-BASED RODS, ELECTRODES AND WIRE Stoody has a long history of being a leading supplier of wear and corrosion resistant cobalt and nickel-based alloys for commercial and military use. For generations the Stoodite family of cobalt-based bare rods and coated electrodes, open and gas shielded wire, and submerged arc wire have been trusted by manufacturers and government agencies alike to protect against mechanical and chemical degradation due to corrosion, heat, and other wear factors. Many of these AWS and military-certifiable cobalt and nickel-based hardfacing alloys are commonly utilized today in power generation, chemical and petrochemical production, fluid handling and transportation, pulp and paper production, agricultural and food-related production, and steel manufacturing to name just a few of the many industrial applications. The Stoodite® line of cobalt-based alloys are individually designed to deliver specific characteristics and performance in harsh environments - typically those involving mechanical and chemical degradation with the potential for other contributing wear factors including heat. With SMAW, GMAW, and SAW process options available, Stoodite cobalt-based alloys typically offer anti-galling, high temperature hardness, and resistance to cavitation erosion while bonding well with weldable alloy steels and stainless steels. The Stoody line of nickel-based alloys are also designed for use on low and medium carbon steels, stainless steels, and cast irons. These superior nickel-based products offer abrasion and impact resistance and typically maintain a high level of hardness at temperature with resistance to galling, pitting, and corrosion. The Stoody alloys presented here are the most popular cobalt and nickel-based hardfacing and high alloy products currently being utilized in real world applications. For assistance in selecting the right hardfacing and high alloy products for your wear resistance needs, contact Stoody engineering or your territory sales manager. If your situation warrants a customized cobalt or nickel- based alloy hardfacing solution, Stoody will be there from conceptualization through field application and beyond.

Hardfacing involves applying a consumable with desired wear prpropertiesoperties over a soft base metal surface to enhance resistance to different wear mechanisms. Substrate materials used for hardfacing are mainly steel, while the alloys of carbide forming elements dominate the surfacing consumables. PowderPowder metallurgy, atomisation and granulation are methods of producing hardfacing alloy powder. Most welding methods were identified to be successfully used in applying consumable on substrate surfaces. Dilution decreases with iincreasencrease in the number of hardfacing layers. Buffers, butters and buildbuild----upup metals are used to compensate for composition differences to prevent spalling, overcome welding difficulties and make up for badly worn surfaces, respectively. Waffle, stringer and ddotot patterns are the existing hardfacing deposit patpatterns.terns.

In the welding process, the buffer and hardfacing layers were welded onto A572-based material by a nickel–chromium electrode and chromium carbide electrode, respectively. The base metal and electrode materials were controlled by the heating/cooling process during the welding to reduce excessive stress, which could result in a crack in the specimens. The welded specimens were examined by visual and penetrant inspections for evaluating the welding quality. The macro–micro structure of the deposited layer was investigated; scanning electron microscope with an energy-dispersive X-ray spectrometer (SEM-EDS) and XRD were used to characterize structural properties, elemental compositions, and crystallite sizes of the welded specimens.

    International Journal of Application or Innovation in Engineering & Management (IJAIEM) Web Site: www.ijaiem.org Email: [email protected] Volume 5, Issue 9, September 2016 ISSN 2319 - 4847 A REVIEW PAPER ON RESEARCH WORK DONE IN HARDFACING Rupendra Kumar1, Pratibha Kumari2, Dr. K.L.A. Khan3 1M.Tech Scholar, Department of Mechanical Engineering, Krishna Institute of Engineering & Technology, Ghaziabad, U.P. 2 Associate professor, Department of Mechanical Engineering, Krishna Institute of Engineering & Technology, Ghaziabad, U.P. 3Head of department, Department of Mechanical Engineering, Krishna Institute of Engineering & Technology, Ghaziabad, U.P. ABSTRACT Wear is the biggest factor that controls the performance and life of any machine part. The interaction between functional surfaces in their relative motion causes adverse effects in the surface layers, leading to their deterioration. Most worn parts don't fail from a single mode of wear, but from a combination of modes, such as abrasion and erosion etc. Research is going on over years to reduce the wear either in the form of using a new wear resistant material or by improving the wear resistance of the existing material by the addition of any wear resistant alloying elements. According to researchers hardfacing is the best method for overcoming wear problems of machine parts as it increases the life of machine part and also protects from damage. We can use many types of hardfacing alloys according to requirement, which may be cheap or costly. In this paper an attempt has been made to review the work of some researchers who conducted the experimental studies on different wear resistant hardfacing alloys, which are employed on the substrate surface of material by different welding processes.

  • Hardfacing and Wear Resistant Use Hardfacing and Wear Many Abrasions Occur Not Just Due to a Singular Cause, but Possibly Two Or More Welding Layers Limitation
    Hardfacing General Review Hardfacing process is the most economical way to allow a work to achieve maximum application and usage longevity. As it name suggests, hardfacing is to build up upon the softer base metals’ surface one or multi-layers of hardfacing alloys according to specifi c needs. There are commonly three types of welding process to restore abrasive of wear out work : 1. Build-up If the project base metal suffers great abrasion, use the proper fi ller metal to restore the base metal back to its original dimension on the working piece prior to hardfacing Resistant Use Hardfacing and Wear welding. 2. Buttering When the fi ller metal for hardfacing layer and the base metal’s mechanical properties along with physical property have great variation, it is difficult to weld the two together; hence, it is essential to select the proper fi ller metal for the project base metal to serve as a buffer in reducing the incompatibility. 3. Hardfacing Hardfacing and Wear Hardfacing also known as surface hardening welding is achieved by welding the wear resistant layer onto base metal or surface layer for the purpose of extending the longevity Resistant Use of mechanical equipment. It is normally limited to two to three welding layers. How to select the proper hardfacing fi ller metal : Hardfacing General Review Welding fi ller metal is selected according to the following criteria : 1.Base metal will affect the selection of fi ller metal for base (root ) layer, for example: a. Mn Steel: for equipment suffered severe impact condition. Use high Mn content filler metal to restore the base metal to its original size.
