Spraying tungsten powder has the advantages of uniform powder particle size, good fluidity, corrosion resistance, etc. It is commonly used in thermal spraying coating and wear-resisting high-temperature component coating materials and diamond nesting materials. Products sprayed tungsten powder requires has the characteristic that high surface hardness, good toughness, wear resistance, and corrosion resistance.
Best physical performance requirements:
Uniform powder particle size, screening +60mesh ≤2%, -325mesh≤10%;
Good fluidity, hall flow rate ≤12s/50g;
Corrosion resistance, oxygen content≤0.05% (mass fraction), tungsten content of 99.7% or more;
Scott density 7.3~8.9g/cm3;
Tap density 9.0~10.5g/cm3.
Preparation
High quality spraying tungsten powder can be produced through the optimization of tungsten powder mixing, grading screening, pickling water washing, hydrogen drying, and batch processing.
