Embodiment Construction

[0016] The present invention will be further described below in conjunction with embodiment.

[0017] A method for grinding and forming a structured color metal surface based on a blazed grating structure, comprising the following steps:

[0018] (1) Smooth the surface of the metal workpiece so that the surface roughness does not exceed 100nm;

[0019] (2) Use a grinding wheel to grind a specific set of parallel grooves on the surface of the metal workpiece according to specific process parameters.

[0020] The processing object of the inventive method is a metal workpiece made of cemented carbide (such as abrasive tool steel, titanium alloy, etc.); the grinding relevant process parameters in the step (2) of the inventive method are as follows: the selection specification for grinding is grinding Choose a grinding wheel with a diamond particle size of 1000#-8000# and a resin bonded abrasive with a concentration of 100%-150%. When grinding, the angle between the grinding wheel...

Abstract

A method for forming a structural color metal surface based on a blazed grating structure through grinding with a grinding wheel comprises the following steps that (1) the surface of a metal workpiece is flattened, so that the surface roughness of the metal workpiece does not exceed 100 nm, and the metal workpiece is made of cemented carbide; and (2) the grinding wheel is used for grinding a parallel groove set in the surface of the metal workpiece according to set process parameters; the process parameters are shown as follows: the included angle between the grinding wheel and the surface of the workpiece is 5-30 degrees, the rotating speed of the grinding wheel is 1000-3000 rpm, the feed speed is 20-100 mm/min, and the grinding depth is 1-5 microns; and once grinding of a groove is completed, the grinding wheel is shifted by 3-20 microns relative to the workpiece, and grinding of the next groove is conducted. The metal surface formed through the method is of a specific micro structure and can not only show structural color as a blazed grating but also have better hydrophobicity compared with the pre-machined surface, thereby having higher corrosion resistant ability and lower fluid flow resistance.

Description

technical field [0001] The invention relates to the field of metal surface finishing, in particular to a method for grinding and shaping a structural color metal surface based on a blazed grating structure with a grinding wheel. Background technique [0002] For decorative purposes, changing the color of metal appearance at this stage relies on dyes. Dyeing with dyes will not only cause environmental pollution, but also easily fade and fade (especially when encountering certain chemical reagents). It can be seen that it is of great significance to study how to overcome the above-mentioned disadvantages or deficiencies in dyeing. [0003] Structural color, also known as physical color, is a luster caused by the wavelength of light and has nothing to do with pigment coloring. It will not fade or fade even when it encounters chemical reagents. It can be seen that if a microstructure capable of showing structural color can be processed on the metal surface, and the metal surfa...
