Method for manufacturing logo pattern based on different color characteristics of metal or alloy

Abstract

The invention particularly relates to a method for manufacturing a logo pattern based on different color characteristics of metal or alloy, and belongs to the field of thermal spraying and laser etching. The method for manufacturing the logo pattern based on different color characteristics of metal or alloy comprises the steps that (1) the portion, to be marked with the pattern, of the surface ofa to-be-manufactured object is cleaned, and the portion, not to be marked with the pattern, of the surface of the to-be-manufactured object is covered to be prevented from being stained; (2) the portion to be marked is sprayed through a thermal spraying device by means of the thermal spraying technique; and (3) mark contents are typeset through a computer, and a laser etching machine and a laser carving machine head are controlled through the numerical control technique to conduct etching. The method is mainly used for metal products in the oil field industry, the ship industry, the military industry, the automobile industry, the power industry and the like and can be widely used for marking articles used in severe working conditions with full-life-circle patterns. Character patterns, figure patterns, two-dimensional bar patterns and bar code patterns formed through the method are easy to recognize visually and can be recognized and input through machine-based code scanning, and backstage management is facilitated.

Description

technical field [0001] The invention belongs to the fields of thermal spraying and laser etching, and in particular relates to a method for making identification patterns based on different color characteristics of metals or alloys. Background technique [0002] The identification pattern involved in the traditional surface identification technology is often produced by printing and pasting, painting, hanging, stamping, embedding, etc., which is easy to wear off or cause damage to the surface of the object. Traditional thermal spraying technology is mainly used in anti-corrosion, wear-resistant and other applications. It refers to heating and melting the coating material, atomizing it into extremely fine particles with high-speed airflow, and spraying it on the surface of the workpiece at a high speed to form a coating. Layer, according to the need to choose different layer removal materials, can obtain one or more performances in terms of wear resistance, corrosion resistan...
