Rise in the efficiency of the use of cemented carbides as a matrix of diamond-containing studs of rock destruction tool
Source abstract
Abstract
To improve strength and plasticity of a matrix of diamond-containing studs for rock destruction tools and thereby to increase their efficiency, we offer to replace the VK6 and VK10 carbides currently used as a matrix with the VK6S and VK10S alloys based on a high-temperature tungsten carbide. These alloys feature an increased work of plastic deformation and ultimate strain. For this reason, they ensure, by the Morrow equation, a higher service life of the carbide matrix and add to the diamond grit retention in it. The efficiency of diamond-containing studs based on VK6S and VK10S alloys is further increased if they are strengthened by heat treatment.
