Description
技术领域technical field
本发明涉及一种提高锆基非晶合金耐磨耐腐蚀性能的方法，属于耐磨耐腐蚀非晶合金材料制备技术领域。The invention relates to a method for improving the wear-resistant and corrosion-resistant properties of zirconium-based amorphous alloys, and belongs to the technical field of preparation of wear-resistant and corrosion-resistant amorphous alloy materials.
背景技术Background technique
腐蚀磨损行为是材料应用过程中广泛存在的问题，给社会的经济发展造成了巨大的危害。解决和延缓腐蚀磨损造成的设备损坏，研究材料的腐蚀磨损机理，提高材料耐磨耐蚀性是现阶段材料领域研究的难点和重点。由于锆基块体非晶内部特殊的原子结构，使其具有高强度、高弹性极限、高耐蚀性能等优点，并在耐磨耐腐蚀设备中的得到广泛应用。Corrosion and wear behavior is a widespread problem in the application of materials, which has caused great harm to the economic development of society. Solving and delaying the equipment damage caused by corrosion and wear, studying the corrosion and wear mechanism of materials, and improving the wear and corrosion resistance of materials are the difficulties and focuses of the research in the field of materials at this stage. Due to the special atomic structure inside the zirconium-based bulk amorphous, it has the advantages of high strength, high elastic limit, high corrosion resistance, etc., and is widely used in wear-resistant and corrosion-resistant equipment.
目前，有大量学者对锆基非晶合金耐磨耐腐蚀性能进行研究。当前研究者已进行的研究结果表明，非晶材料的性能主要包括：具有优异的机械力学性能。研究发现，Zr基非晶材料的断裂强度已经分别达到2070 MPa。与传统晶体材料相比，由于非晶相得存在，使其具有更加良好的耐腐蚀能力，可在一些复杂苛刻的工况条件下长期使用。微量元素添加法被广泛应用于非晶合金制造领域。非晶合金的玻璃成型能力和性质对其化学组成的影响很大，所以微合金化可以很好地调节非晶合金的性质。研究发现0.1%的硼+0.2%的硅+0.1%的铅可以有效地减少氧对非晶合金的不利影响；适当添加N可以通过抑制Zr和Ti基大块非晶合金中竞争晶体的形成来促进玻璃的形成；Cr和Nb涂层促进了摩擦表面连续致密氧化膜的形成，显著降低了非晶涂层的磨损率。但是微合金化方法会增加非晶材料的制造成本，不符合经济效益指标。通过电脉冲方法提高锆基非晶合金耐磨耐腐蚀性能可以有效降低生产成本。目前，非晶合金的主要结构弛豫手段是进行热处理，传统的热处理工艺成本较高，耗时较久，传统的等温退火工艺往往难以获得所需的结构驰豫效果。因此研发新的热处理方法，以满足实现锆基非晶合金快速结构驰豫提高锆基非晶合金耐磨耐腐蚀性能。At present, a large number of scholars have studied the wear and corrosion resistance of zirconium-based amorphous alloys. The results of research conducted by current researchers show that the properties of amorphous materials mainly include: excellent mechanical properties. The study found that the fracture strength of Zr-based amorphous materials has reached 2070 MPa respectively. Compared with traditional crystal materials, due to the existence of amorphous phase, it has better corrosion resistance and can be used for a long time under some complex and harsh working conditions. Trace element addition method is widely used in the field of amorphous alloy manufacturing. The glass forming ability and properties of amorphous alloys have a great influence on their chemical composition, so microalloying can well adjust the properties of amorphous alloys. It is found that 0.1% boron + 0.2% silicon + 0.1% lead can effectively reduce the adverse effect of oxygen on amorphous alloys; appropriate addition of N can inhibit the formation of competing crystals in Zr and Ti-based bulk amorphous alloys. Promote the formation of glass; Cr and Nb coatings promote the formation of a continuous dense oxide film on the friction surface, significantly reducing the wear rate of the amorphous coating. However, the microalloying method will increase the manufacturing cost of the amorphous material, which does not meet the economic benefit index. Improving the wear and corrosion resistance of zirconium-based amorphous alloys by means of electric pulses can effectively reduce production costs. At present, the main means of structural relaxation of amorphous alloys is heat treatment. The traditional heat treatment process is costly and takes a long time. The traditional isothermal annealing process is often difficult to obtain the required structural relaxation effect. Therefore, a new heat treatment method is developed to meet the rapid structural relaxation of zirconium-based amorphous alloys and improve the wear and corrosion resistance of zirconium-based amorphous alloys.

Perform cyclic AC pulse + DC pulse heat treatment heat treatment. The temperature of the pulse heat treatment is close to the crystallization transition zone of the amorphous alloy. Cycle AC The pulse makes the entropy value of the amorphous atoms significantly increase, the arrangement of the atoms is more chaotic, and the long-range is more disordered, which improves the hardness and strength of the material; DC pulse treatment makes the amorphous atoms form an orientation relationship in the short-range order, and the atoms tend to be more (111) Alignment to improve the wear resistance and corrosion resistance of amorphous.
本发明的应用效果：Application effect of the present invention:
