Embodiment Construction

[0036] The following describes several preferred embodiments of the present invention with reference to the accompanying drawings, so as to make the technical content clearer and easier to understand. The present invention can be embodied in many different forms of embodiments, and the protection scope of the present invention is not limited to the embodiments mentioned herein.

[0037] Such as figure 1 and figure 2 As shown, the titanium-based mixed powder in this example is observed under 100X and 200X. Its shape is nearly spherical, the particle size is between 75-150 μm, and its fluidity is good, which is suitable for laser cladding. Among them, the titanium-based mixed powder includes pure Ti and AlB 2 ; 2 The mass percentage of Ti is 15%-30%, and the rest is pure Ti. More preferably, the present embodiment selects AlB 2 The mass percentage is 20%.

[0038] The titanium-based mixed powder in this example is prepared by a ball milling process. Among them, the optim...

Abstract

The invention discloses titanium-based mixed powder for preparing a laser cladding coating and relates to the technical field of laser cladding. The titanium-based mixed powder comprises pure Ti and AlB2, wherein the mass percent of AlB2 is 15%-30%, and the rest is pure Ti. The titanium-based mixed powder is prepared through a ball milling technology, in the process of a laser cladding technology,the titanium-based mixed powder and the Ti element generate TiB and Ti3Al second phase particles in a molten pool, and the Ti3Al second phase particles, the Al element in an alpha-Ti coating substrate in a solid solution mode, and oxygen generate Al2O3 on a surface oxide layer in a high temperature oxidation environment. The developed titanium-based mixed powder meets the requirements of high abrasion resistance, high-temperature oxidation resistance and other properties for the cladding layer of the surface of a titanium alloy part, the laser cladding coating is free of cracks, pores, inclusions or other defects, and hardness can reach 800 HV0.3.

Description

technical field [0001] The invention relates to the technical field of laser cladding, in particular to a titanium-based mixed powder used for laser cladding coatings, a manufacturing method and an application thereof. Background technique [0002] With the development of laser technology, laser cladding technology has been widely used to modify the surface of parts. The main applications include improving its surface wear resistance, corrosion resistance, and oxidation resistance. Different from traditional surface strengthening technologies such as surface carburizing and thermal spraying, laser cladding technology uses high-energy and high-density laser beams to melt the metal powder and the surface of the substrate at the same time to achieve a metallurgical bond between the coating and the substrate. At the same time, a surface enhanced cladding layer with structure and properties completely different from the base material is obtained on the surface of the substrate. ...
