example 1

[0024] (1) Recycling the "strip-shaped" waste formed by 30CrMnSi turning, 30CrMnSi turning waste such as figure 1 As shown, the thickness is 400 μm and the width is 3000 μm. use alcohol for figure 1 The waste material shown is ultrasonically cleaned to remove oil and impurities on the surface of the waste material.

[0025] (2) Design a mechanical straightening equipment to straighten the "strip-shaped" turning waste by self-made straightening equipment, and polish the surface oxide film for laser cladding test. Corrective equipment such as figure 2 As shown, it is mainly composed of two components, 1 is the reel of the equipment, and the flexible "strip-shaped" waste can be placed in the reel for rotation, and 2 is the two-by-two fixed roller, which is used to bite the flake-shaped turning waste At the same time, there is a grinding function on the runner, which can grind away the oxide film on the surface of the sheet during the rolling process. The angle between the rol...

example 2

[0028] (1) Recover the "strip-shaped" waste formed by turning 30CrMnSi, with a thickness of 400 μm and a width of 3000 μm. Carry out pretreatment with example 1 method.

[0029] (2) Still according to the method of Example 1, design the straightening equipment to straighten and polish the surface oxide layer of the "strip-shaped" turning waste.

[0030] (3) The straightened turning waste is sent into the molten pool by wire feeding, and becomes a molten state under the action of a high-energy beam laser heat source to form a metallurgical coating. The laser cladding parameters are the same as in Example 1.

example 3

[0032] (1) Recycle the "rolled strip" waste formed by turning 30CrMnSi, with a thickness of 600 μm and a width of 4000 μm, and perform pretreatment according to the method of Example 1,

[0033] (2) Still according to the method of Example 1, design the straightening equipment to straighten and polish the surface oxide layer of the "strip-shaped" turning waste.

[0034] (3) Place the sheet on the surface of the substrate according to the method of Example 1, and use the laser beam to scan to prepare the coating. Laser cladding parameters: laser power is 2000W, scanning speed is 9mm / s, spot diameter is 3mm, and the gun head has no deflection .

Abstract

The invention discloses a turning and recycling laser cladding material and a coating preparation method, and relates to an environment-friendly manufacturing method by taking recycled turning waste as a laser cladding material. The method mainly comprises the steps of recycling the turned strip-shaped waste materials, carrying out ultrasonic cleaning to remove surface oil stains and impurities, mechanically straightening the turned strip-shaped waste materials through self-made correcting equipment, eliminating turning oxide films on the surfaces of the turned strip-shaped waste materials through the correcting equipment, and finally carrying out laser cladding on the corrected strip-shaped materials to prepare a surface metallurgical coating. The method recycles the waste in an environment-friendly mode to prepare the surface metallurgical coating with good forming and no defect, and creates great economic value for the manufacturing field.

Description

technical field [0001] The invention belongs to the field of surface engineering and relates to a method for obtaining and coating a laser cladding material which is reused after turning. Background technique [0002] With the rapid development and progress of modern technology and industry, the demand for materials in various industries is also getting higher and higher. Modern industry is increasingly demanding that materials work in extreme environments, such as high temperature, high load, wear-resistant and other environments. , under such extreme working conditions, components are often prone to failure on the surface of the material. In response to such problems, surface engineering technology is an effective means of protection and repair. Surface engineering is to change the morphology, chemical composition, tissue structure and stress state of solid metal surface or non-metal surface through surface coating, surface modification or multiple surface technology comp...
