<p>Ceramic turbine wheels (10) are balanced to minimize rotational vibrations by bonding silica-based glass pads (18) to the wheel (10). The pads (18) are formed from a mixture of sodium silicate, water and a fine ceramic powder, preferably of a composition similar to the underlying ceramic turbine wheel (10). The weighted pads (18) are machined, without damage to the underlying ceramic wheel, to achieve proper balance.</p> |
