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.

工具复合材料的孔隙率和吸水性是提高超级磨料砂轮耐磨性的因素。第2部分。超级磨料复合材料多孔空间中的水冻结

首次定义了条件，以便在复合材料的吸水和随后的水冻结过程中利用超级磨料复合材料的孔隙率。本文探讨了复合材料在这种条件下所经历的物理机械性能（硬度，强度特性，电导率）的变化。研究了冷冻时磨具的耐磨性能。
