Problems solved by technology

Some existing technologies often prepare hydrophilic ceramics from the performance of the ceramic material itself, or need to redesign and prepare a hydrophobic coating, resulting in high cost, complicated process, and difficulty in popularization.
At the same time, these technologies generally have the disadvantages of immersion in chemical potions, chemical pollution, cumbersome steps, time-consuming and low preparation efficiency, which limit their practical applications.

Abstract

The invention provides a method for ultrafast laser treatment of an aluminum oxide ceramic blade surface. The method comprises the following steps: firstly, a ceramic blade sample is dried or aired by cold air after being cleaned by de-ionized water and anhydrous ethanol; then, the surface of the sample is treated by a laser processing technology after related process parameters are adjusted by ultrafast laser; and multiple micronano-structures are machined on the surface of the sample, so that the surface of the cutter becomes from loving of cutting liquid to super-loving of the cutting liquid. The preparation method is simple in process, can be performed in open environment, and is convenient to operate, high in efficiency, low in energy consumption, low in cost, green, environment-friendly and liable to realize industrial application.

Description

technical field [0001] The invention relates to the technical field of surface modification of cermet substrates, in particular to a method for ultrafast laser treatment of the surface of an alumina ceramic blade. Background technique [0002] Alumina is different from other tool materials in that its chemical properties are stable and its oxidation resistance is particularly good. Its cutting edge can cut for a long time even in a red hot state, so alumina ceramic tools are especially suitable for high-speed cutting. Due to the poor wettability of alumina blades to most metals, it is difficult to bond with metals. When cutting, the friction coefficient is low, the cutting force is small, and it is not easy to produce built-up edge and adhesive wear, so the workpiece is easy to get a smoother finish. high surface. Alumina cutting tools are suitable for processing most metal materials, especially for cutting chilled cast iron or hardened steel. The use of fine turning instea...
