Porosity and Water Absorbability of Tool Composite Materials as Factors of Improving Wear Resistance of Superabrasive Grinding Wheels. Part 1. Superabrasive Composites.

The conditions for making use of porosity of superabrasive composites in the process of water absorption have been defined for the first time. It is shown how physical-mechanical properties (hardness, strength, conductivity) of the composites vary under the influence of water absorption, the duration of this effect has been determined, and the conditions for increasing wear resistance of the composites in grinding tools have been clarified.
