Special machine tool equipment for laser cladding of high-entropy alloy

Abstract

The invention discloses special machine tool equipment for laser cladding of high-entropy alloy, and relates to special equipment for laser cladding of high-entropy alloy, which comprises a special machine tool body for laser cladding of high-entropy alloy, a chuck for clamping a workpiece is arranged on the special machine tool body for laser cladding of high-entropy alloy, and the chuck is driven by a servo motor arranged in a servo motor box. An electric tailstock used for being matched with clamping and rotating of a workpiece, a sliding rail used for installing a cladding head, a laser device and a powder mixing system are arranged on the special machine tool body for laser cladding of the high-entropy alloy. The machine tool head servo motor can drive the workpiece to rotate at a high speed so as to ensure that the molten pool can move at a high speed in the laser cladding process, so that the high-speed rotation of the workpiece enables the cooling speed of the molten pool to be further increased, diffusion of elements and segregation of the elements can be effectively reduced, the grain size can be effectively reduced, and the mechanical and corrosion-resistant performance of a coating can be improved.

Description

technical field [0001] The invention relates to a special equipment for laser cladding high-entropy alloys, in particular to a special machine tool equipment for laser cladding high-entropy alloys. Background technique [0002] High-entropy alloys have the characteristics of wear resistance, corrosion resistance, and excellent mechanical properties under high and low temperature environments due to their unique multi-group element composition. At present, laser cladding is a typical way to prepare high-quality high-entropy alloy coatings on the surface of parts. However, when ordinary laser cladding equipment is used for high-entropy alloy powder cladding, there are disadvantages such as uncontrollable grain size, inability to use elemental powder for in-situ alloying or poor in-situ alloying effect. [0003] In view of the above problems, the present invention provides a special machine tool for laser cladding high-entropy alloys. SUMMARY OF THE INVENTION [0004] The ob...
