Abstract

The invention discloses a laser cladding device and method based on ultrasonic-Lorentz force composite vibration, which solves the problems of insufficient vibration capacity and many bubbles in the cladding layer in the prior art, and achieves effective cladding layer cracks , The effect of suppressing and reducing air bubbles, the scheme is as follows: the clamping chuck is used to support the cladding substrate; the first conductive head is set opposite to the clamping chuck, and is used to apply a current field to the cladding substrate from the end ; The second conductive head is set on the machine bed, and is used to apply a current field to the cladding substrate from below; the laser head is set on the top of the machine bed, and is used to cladding the cladding substrate from above; The coil includes two magnetically conductive cores, which are respectively arranged on both sides of the laser head, and each magnetically conductive core is wound with a helical coil; an angle adjustment mechanism for an ultrasonic generator; the ultrasonic generator is supported by an angle adjustment mechanism for an ultrasonic generator , which is used to apply an ultrasonic field to the cladding substrate at a set angle.

Description

technical field

[0001] The invention relates to the improvement of cladding layer performance, in particular to a laser cladding device and method based on ultrasonic-Lorentz force composite vibration. Background technique

[0002] Laser cladding is an advanced surface modification technology that uses a high-energy density laser beam to melt the cladding material and the surface of the substrate to form a cladding layer with metallurgical bonding characteristics. Irradiation causes the cladding material moving at a certain speed and the surface microlayer of the substrate to be rapidly heated and melted to form a rapid solidification process of an alloy layer with completely different composition and properties from the substrate, the purpose of which is to improve the wear resistance and corrosion resistance of the substrate , heat resistance, fatigue resistance, oxidation resistance and electrical properties, so that the surface of engineering materials can obtain good co...
