On grinding applications of variously dispersed powders of compacts based on synthetic and natural diamond with carbon binder

Аннотация

The possibility of using variously dispersed powders of compacts based on synthetic and natural diamond with carbon binder in grinding wheels for machining hard alloys is studied. The partial (50%) or complete replacement of synthetic diamonds with the compact powders containing diamond grains coated with a superhard shell of Yakut diamond micron powders—the waste of gem-cutting operations—in a carbon binder is shown to provide a significant (more than three-fold) improvement of wear resistance of diamond grinding wheels.
