Hardfacing with Tungsten Carbide for Wear Resistance

Hardfacing is a welding process of build-up deposits of alloys to resist corrosion, abrasion, high temperature, or impact.  Hardfacing increases a part’s service life and can thus directly affect machinery efficiency and reduce the amount of equipment that is scrapped.  When addressing wear resistance needs, high-deposit hardness material does not always provide the best overall wear resistance.  Rather, when choosing a hardfacing alloy for wear resistance, the presence of carbides must be considered in addition to hardness properties.

Alloys that are typically used for hardfacing include iron-base alloys, cobalt-base alloys, nickel-base alloys, and tungsten carbides.  Tungsten carbide is one of the most superior metal-to-earth abrasion resistant hardfacing materials.  When compared to a chromium carbide overlay, a machine part hardfaced with tungsten carbide can experience a 3 to 5 time increase in service performance.

Polymet offers two tungsten carbide wires, POLYTUNG NiBWC, with a Ni-B-Si-matrix, and POLYTUNG NiCrBWC, with a Ni-Cr-B-Si-matrix.  The matrix is responsible for roughly 35-40% of the deposit alloy while the tungsten carbide consists of the remaining 60% of the deposit alloy.  Both of these alloys have a macro crystalline carbide structure.  Some of the applications that are hardfaced using Polymet’s POLYTUNG wires are dredge cutter heads & teeth, ID elbows & pipes, oil tool bits, and bucket teeth.  Hardfacing with tungsten carbide materials can be applied to industries such as mining, oil & gas, and construction.

Hardfacing Wire Manufacturer Polymet Corporation Celebrates 45th Anniversary

Polymet Corporation, a leading producer of hardfacing wire, welding wire and thermal spray wire, is celebrating its 45^th year in business.

Polymet began as a small aerospace consulting firm and grew into a pioneer in the gas turbine hardfacing world.  By developing propriety processes to produce very hard and brittle alloys in small diameter wire form, Polymet solidified its position as the global leader in the production of wire for the worlds most demanding and intense applications.  Polymet’s product line has grown beyond the alloys once thought impossible to produce  and now incorporates a full line of industrial hardfacing alloys, welding and thermal spray materials.

The materials that Polymet produces are engineered for some of the most demanding applications in the world.  From iron based amorphous alloys to nickel based alloys for the aerospace industry, Polymet manufactures the highest quality wire in the world for both twin wire arc spray and flame spray operations.  Polymet’s unique hot extrusion technology allows it to produce cobalt based hardfacing alloys for GTAW, hot wire TIG, plasma and laser welding.  Polymet also offers aerospace grade welding wire whose cleanliness and level of quality have caused customers around the world to demand Polymet processing in their specifications.

Polymet produces wire for gas turbine engines, nuclear reactors, down hole drilling equipment, high pressure valves, saw blades and many other surfacing applications. Polymet engineers all of its products to the highest standard of quality to ensure integrity in each piece of wire.

“Throughout these 45 years, there is one fact that remains the foundation of our belief system at Polymet.  Without our dedicated employees, loyal customers, dependable suppliers and strategic partners throughout the world, there would be no Polymet.  The relationships and friendships that have been forged throughout the history of Polymet are what keep us energized to do what we do.” – says Bill Mosier, president of the company.
