Nejčastější dotazy
Q: What is the benefit of metal alloy over pure elemental powders?
A: Alloying enables significantly enhancing key attributes like strength, corrosion resistance, hardness, conductivity etc over any single element’s intrinsic limitations through metallurgical mechanisms and Second Phase control.
Q: How small can metal alloy powder sizes get produced?
A: Inert gas atomization can generate nano-scale metal powders down below 10 nanometers at the leading edge of current commercial capabilities. Chemistries and morphologies remain an intense R&D area as new methods get pioneered.
Q: Is post-processing of powders mandatory before part fabrication?
A: Besides sieving into precise size fractions, additional conditioning like deoxidation, annealing, coating and blending can get utilized to modify powder characteristics assisting fabrication process performance, densification behavior and final component property targets.
Q: What dictates the cost difference between grades?
A: Processing intricacy, alloying elements pricing, R&D investments, production volume and specification requirements control pricing – exotic highly engineered powders prove far more expensive than common workhorse varieties.
