DSM-0235.0 – Woka 3700 WC 20CrPowder Products:Introduction 3700 series materials are agglomerated and sintered powders for thermal spray, containing 73% chromium carbide as hard phase materials particles. The particle shape is mainly spheroidal.tion and a lower apparent density than the standard WOKA 3700 series materials. This results in higher deposition efficiencies and denser coatings for improved corrosion resistance while maintaining the good oxidation and wear properties of coatings produced using the WOKA 3700 series ManufactureAgglomerated and sinteredSpheroidalApparent DensityFree-flowingService TemperatureCorrosive / oxidative wear resistanceProcessHVOF or HVAFMaterial Product Data SheetTungsten Carbide – Chromium Carbide – Nickel SEM Photomicrographs showing the morphology (top) and the microstructure (bottom) of WOKA 3703 powder.

cations where a higher hardness is required choose a tungsten carbide material with a cobalt-chromium matrix such as WOKA 365x series products or WOKA 360x series products. If better corrosion resistance in HCl solutions is required, use a tungsten carbide material with a cobalt-chromium matrix such as WOKA 365x series products, or WOKA 360x series products.If higher service temperature is required or better corrosion resistance in NaOH solutions, choose a chromium carbide with a nickel-chromium matrix such as products.
