Porosity and Water Absorbability of Tool Composite Materials as Factors of Improving Wear Resistance of Superabrasive Grinding Wheels. Part 2. Water Freezing in Porous Space of Superabrasive Composites

详细

For the first time the conditions have been defined for making use of porosity of superabrasive composites in the process of water absorption and subsequent water freezing in the composite. The paper addresses the changes in physical-mechanical properties (hardness, strength characteristics, electrical conductivity) the composites undergo under such conditions. The behavior of wear resistance of grinding tools upon freezing has been studied.
