摘要：

The paper describes an energy-efficient technology for producing a diamond-bearing composite material on the surface of a sintered diamond-aluminum part by microarc oxidation. The material formation time and energy consumption cost is reduced through replacing 10-25 vol% aluminum powder with white corundum powder. The corundum powder grit should be 5-6 times less than the diamond grain size. The material has high wear resistance and volumetric cutting ability. Frictional characteristics are improved due to an increasing matrix hardness through increasing a modification of Al2O3 in its composition. The new material might be a tool for precision abrasive microprocessing of hard materials. (C) 2020 Elsevier Ltd. All rights reserved.
