Abstract

When conducting a powder blasting to a spinning cylindrical workpiece in the codition of 0.76~1.5(mm) in nozzle size, 1~5(atm) in working pressure, and 40~100(mm) in stand off distance, the value of surface roughness becomes under $0.283{\mu}m$, which is not enough to expand a bonding area. In the case of horizontal transfer blasting with 0.76mm of nozzle size, 100mm of stand off distance, and 2~5atm of working pressure, $0.5{\sim}0.7{\mu}m$ of surface roughness has achieved regardless of feed rate.
