Abstract

The invention discloses a method for handling high current pulsed electron beams (HCPEB) on the surface of a hard alloy cutter, belonging to the technical field of handling the surfaces of materials. The method is characterized by comprising the following steps: cleaning the surface of the hard alloy cutter, fixing the hard alloy cutter on a worktable, and vacuumizing to a pre-working value. According to modification requirements of a cutter to be handled, the working parameters of the HCPEB (High Current Pulsed Electron Beam) is selected and include electron accelerating voltage, pulse lasting time, energy density, pulse interval time, handling times and the like. Finally, the HCPEB is operated to carry out processing and handling on the parts needed to be handled on the surface of the hard alloy cutter. After handling is finished, the vacuum exhaust is carried out to take out the cutter. The method has the beneficial effects of improving the surface performance and the service life of the hard alloy cutter, overcoming the problems of complicated process, poor binding force of a coating and a substrate, high cost and the like existing in the prior art, and being simple in handling process and stable for quality control. The handled surface tissues of the cutter are uniform and refined, and the modified layer is deep.

Description

technical field [0001] The invention belongs to the technical field of material surface treatment, and relates to a new method for improving the surface performance and service life of a cemented carbide tool, specifically a method for treating the surface of a cemented carbide tool with a high-current pulsed electron beam Background technique [0002] Since the beginning of the 21st century, with the globalization of manufacturing technology, the competition in the manufacturing industry has become more intense, which has brought great challenges to manufacturing technology. The quality, performance and service life of cutting tools directly affect the quality, cost, productivity and economic benefits of production enterprises. Therefore, people have been working hard to study new tool materials, or use new surface treatment techniques to improve the performance and life of the tool. [0003] In the past 30 years, tool materials, which are the most basic elements of cuttin...
