DSMW-0019.4 – Cast Tungsten Carbide / Ni[Cr]BSi PTA Powder Material Product Data SheetCast Tungsten Carbide / Nickel [Chromium] Boron Silicon Powders for Plasma Transferred Arc (PTA)PTA Powder Products: Introduction51027 are blended powders of cast tungsten carbide (CTC) ManufactureMatrix: spheroidalApparent DensityFree-flowing powderService TemperatureWear resistanceProcessPTASEM photomicrograph showing the morphology of PlasmaDur 51027 powder DSMW-0019.4 – Cast Tungsten Carbide / Ni[Cr]BSi PTA Powder51027 weld overlays have a matrix hardness of approximately 50 HRC which provides very good abrasion wear resistance with good impact resistance. These products are often used in oil exploration and earth moving equipment, where high corrosion resistance is not required.PlasmaDur 51027, within the exact same matrix alloy.increases the product's apparent density, which improves its flowability and can produce denser overlays.to higher abrasive and erosive wear conditions

where mild corrosion is a concern.PlasmaDur 51222 is quite good for abrasive and erosive wear conditions where impact is not a concern. Furthermore, its high chromium content results in overlays with better corrosion resistance.Due to the higher matrix hardness of PlamaDur 51202 ed in overlays produced from these materials.

ith a hardface coating matrix hardness of approximately 40 HRC which provides good abrasion and reasonable impact resistance. Oil exploration and Oerlikon Metco offers a wide variety of tungsten carbide wear-resistant coating materials. Please refer to our maRepresentative for more information on available material Where spray and fuse applications suffice, WOKA that provides very good abrasion resistance characteristics. WOKA 53025 shows excellent weldability producing a crack-free, highly impact resistant deposits while deposits made from WOKA 53045 exhibit high erosion resistance.Spray and fuse products that contain tungsten carbide among others. These materials are applied using thermal spray processes. Nickel- and cobalt-based self-fluxing alloys without hard phase that are thermal sprayed and subsequently fused and other products. These materials form fully dense coatings with good corrosion resistance. Recommended Coating ProcessPlasma Transferred Arc (PTA)MicrohardnessHardnessH
