Abstract
The results of the study opportunities of application compacted structured by nanocarbon bond dispersed powders of synthetic, natural diamond and boron carbide in the grinding wheels for the processing of cemented carbide. For this purpose were selected Diamond powders AC 6 125/100 and on their surface was damaged composite material based on sub-micron (3/0) fractions of natural diamond powders, as well as boron carbide micropowders, compacted carbon pile method physicochemical synthesis at a pressure lower than atmospheric pressure. In this paper, the main task was to compare features of the operational characteristics of the diamond community, primarily their durability when used in their working layer dispersed of abrasive powders of new composite materials based on natural diamond and boron carbide and set conditions for their effective application in grinding wheels. In this paper, the main task was to compare features of the operational characteristics of the diamond community, primarily their durability when used in their working layer dispersed of abrasive powders of new composite materials based on natural diamond and boron carbide and set conditions for their effective application in grinding wheels. It is shown that partial (50 %) or total replacement of synthetic diamonds compacted powders that contain diamonds, surrounded by the original coating of mìcropowders natural diamond or boron carbide mìcropowders structured by nanocarbon bond, allows you to significantly increase wear resistance diamond grinding wheels.
