Description
Technical Field
The invention belongs to the technical field of laser cladding surface modification, and particularly relates to iron-based alloy powder for laser cladding of the outer surface of a plunger of a hydraulic support.
Background
The hydraulic support is the core equipment of the fully mechanized mining face of the coal mine, can safely and reliably support and control the whole stope face, isolate the mining area and effectively ensure the safe and smooth operation of mining work. In the working process, the plunger of the hydraulic support is easy to be impacted by splashed coal gangue to cause surface damage, the underground environment is humid and has high relative humidity, and a large amount of SO is existed2、H2S、Cl2And the corrosion of the outer surface of the movable column of the hydraulic support is accelerated by various corrosive media, so that the sealing effect of the movable column can be damaged, the problems of pressure loss, pressure relief and the like of an oil cylinder matched with the movable column of the hydraulic support are caused, the lifting force of the hydraulic support is reduced, the production efficiency is reduced, and the production safety is threatened. Due to the fact that the hydraulic support is large in size and high in purchasing cost, the hydraulic support has important significance for repairing the hydraulic support plunger which fails due to abrasion and corrosion under the background that the country advocates building of a resource-saving environment-friendly society and developing of circular economy.
The traditional hydraulic support stand column surface treatment technology mainly adopts an electroplating hard chromium process, although the repair method has low cost, easy operation and good surface quality, the thickness of a coating is limited, large-area peeling and bulging are easy to occur in the use process, the service life is short after repair, the repairable frequency is less, and chromium-containing waste water and waste gas are generated in the electroplating process, so that serious environmental pollution is caused, the health of an operator is harmed, and the national environmental protection policy is not met.
The laser cladding surface modification technology is a metal surface modification technology which is newly raised in recent years, and is characterized in that alloy powder and the surface of a workpiece substrate are melted and solidified into metallurgical bonding by utilizing high-energy laser beams to form a laser cladding layer with specific excellent performance, so that the effect of strengthening the substrate is achieved. At present, a lot of iron-based powder are adopted when the outer surface of a plunger of a hydraulic support is subjected to laser cladding, but because the iron-based powder is not properly matched, the defects of nonuniform structure, incompactness, air holes, cracks, easy pitting corrosion and the like of a cladding layer occur, so that the phenomena of poor corrosion resistance and wear resistance of the laser cladding layer and poor laser cladding strengthening effect of the outer surface of the plunger of the hydraulic support are caused.
Chinese patent CN108559996B provides a laser cladding repair method for the outer surface of a plunger of a hydraulic support (the application date is 3/7/2018), a method for forming chromium-rich carbide (such as Fe-Cr-C) is adopted, a compact passive film is easy to form, the laser cladding layer has better corrosion resistance, C mainly forms carbide with extremely high hardness with elements such as Ni, Cr and the like in alloy, and the hardness of the cladding layer is ensured, so that the use thickness of the cladding layer reaches 0.5-0.6mm, the macroscopic hardness reaches HRC45-55, the corrosion resistance time of an AASS salt spray test is longer than 2000h, and the comprehensive performance of laser cladding for the outer surface of the plunger of the hydraulic support is effectively improved. However, the patent has the following technical defects: the hardness of a cladding layer is improved only by means of formed chromium carbide (nickel and carbon cannot form nickel carbide), the hardness value is not high, the hard phase is few, the cladding layer cannot adapt to complex working conditions, and the cladding layer is not sufficient in protection against splashing coal gangue impact and scratching of an operating tool; secondly, the cladding layer is solidified in a short time, partial metallurgical reaction is incomplete, and the alloy of the cladding layer is uneven and not compact, so that the phenomena of pitting corrosion and the like are easy to occur; the cladding layer has large thickness, which inevitably causes large laser cladding heat input and large heat affected zone formed on the matrix, thus causing the mechanical property of the matrix to be reduced and reducing the service cycle of the whole hydraulic support plunger; fourthly, due to the aging phenomenon, the cladding layer is easy to generate the phenomena of bubbling of drum skin and the like; fifthly, the working period of the repaired hydraulic support plunger is not long enough, and the improvement of the production efficiency is limited.
How to solve the above problems is a critical need for the technicians in this field to work.

4. Niobium and titanium elements capable of forming stable nitrides are added into the cladding layer alloy, niobium and titanium react with nitrogen to form niobium nitride and titanium nitride, crystal grains are refined, the aging phenomenon is eliminated, and the phenomenon of bulging and peeling under the action of stress after the cladding layer is used for a period of time is avoided.
5. The working period of the cladding layer is effectively improved.
