[Tungsten Carbide]:Study of Ultra-fine WC Powder Preparation by Mechanical Ball Milling

Study is made of the vibrating ball miling for ultra-fine WC powder preparation.Coarse,medium and fine WC powders are used for tests at different ball percentage and milling time.The results showed that longer ball milling time cam result in ultra-fine WC powder with FSSS particale size<0.5 μm,while larger ball percentage and longer milling tine can make the particle size smaller yet without any influence on the particle size distribution.The milled powder size distribution is related to that of the primary powder.The longer milling time will result in smaller grain size and larger stress..........Details,please contact the auther, editor.
