Abstract

The invention provides a laser surface alloying method for heavy-duty gears of marine platforms. The method includes: performing gear surface laser micro-texturing, preparing nickel-based abrasion-resistant alloy powder, performing liquid nitrogen cryogenic reaming, laying the nickel-based abrasion-resistant alloy powder in a reamed microtexture area, and subjecting the microtexture area to laseralloying, laser quenching, microtexture area hardness, abrasion resistance and friction coefficient detection and optimization. By a series of processes, laser alloying is performed after gear surfacemicro-texturing; due to adding of abrasion-resistant elements in uniform distribution in the laser alloying process, hardness and abrasion resistance of gear surfaces and gear portions in different depths are effectively enhanced; and service lives of the gears are prolonged.

Description

technical field [0001] The invention belongs to the technical field of laser processing, and in particular relates to a method for laser alloying the surface of a heavy-duty gear on an offshore platform. Background technique [0002] The laser surface micro-texturing process has been proven to be a means to effectively improve the friction and wear properties and bearing capacity of the material surface. In recent years, more and more attention has been paid to the surface modification technology by processing a series of array micropatterns on the friction pair. Moreover, the micro-pits on the surface of the laser micro-textured substrate are steep, and a bonding strengthening mechanism is introduced at the interface after powder coating, and the interfacial bonding strength is significantly improved. [0003] Laser Surface Alloying (LSA) is a new method for local modification of the surface of metal materials, and the laser alloying process belongs to the category of mate...
