Abstract

The invention provides a laser cladding method belonging to the field of laser machining. The laser cladding method is characterized in that a laser cladding layer is formed through melting alloy powder for laser cladding on the surface of an upright of a hydraulic support by utilizing a laser beam emitted by a semiconductor laser; the semiconductor laser takes a semiconductor material as a working substance and emits light by utilizing the transition of the semiconductor material between energy bands; and the upright of the hydraulic support is mainly made of 27SiMn alloy steel materials. The laser cladding method can be used for increasing the energy absorption efficiency of the laser beam and is high in electric energy utilization ratio so that the power consumption is reduced.

Description

technical field [0001] The invention relates to a laser cladding method, which belongs to the field of laser processing and manufacturing. Background technique [0002] The hydraulic support column is a key component of mining equipment. In China, the hydraulic support column is usually treated with chrome plating to prevent surface rust and corrosion. However, the wear resistance of the chrome plating layer is poor. Generally, after 1 to 1.5 years, the chrome plating layer will appear peeling and peeling. Therefore, the emulsion will corrode the surface of the column, which will affect the use effect of the hydraulic support. [0003] The Chinese patent with the announcement CN101875128B discloses a laser cladding method for mining hydraulic support columns, which cladding three layers of metallurgical materials through specific laser cladding process conditions, thereby solving the wear resistance of the surface of mining hydraulic support columns Non-toxic, anti-corrosio...
