Description

technical field [0001] The invention relates to the field of diffusion experiment equipment, in particular to a diffusion experiment device with controllable temperature and pressure. Background technique [0002] Diffusion wear and bond damage will occur when cemented carbide tools are cutting iron-carbon alloys and nickel-based alloys. The essential reason is the element diffusion between the cutter and chips. The main factors are the chemical affinity, temperature and pressure between materials. , concentration gradient, etc. [0003] In order to study the diffusion of elements between the knife and chips, the current experimental method of diffusion between the knife and chips is to clamp or weld the knife and tool materials together, heat them in a high-temperature furnace and then cool them to obtain the results of the diffusion experiment. This experimental scheme not only It is impossible to simulate the relative motion of the tool material and the workpiece materia...
