The SURPREX WC12 and its developmental siblings are an agglomerated and sintered composite powder of WC/12%Co whcih, when thermally sprayed, features remarkably high deposit efficiency and freedom from spitting due to strictly controlled size and strenth of particles. It has been found that there is a strong relationship between average size of WC (raw material) and properties of sprayed coating. The optimized WC/12%Co will be supplied by Fujimi to take account of customer's required thermal spray conditions and properties of coating.
Four types of SURPREX WC12 are available, suitable for different spray guns.
|Type||Particle Size (µm)||Spray Gun||Typical Properties|
