Abstract

The invention provides an abrasion system for simulating various motions of metal in a lead-bismuth alloy environment, and relates to the technical field of material surface motion abrasion testing. The system comprises a lead bismuth alloy environment simulation cavity, the lead bismuth alloy environment simulation cavity is provided with a first metal body and a second metal body which abut against each other, the first metal body is fixed through a clamping device, the clamping device is connected with a horizontal circumferential reciprocating motion mechanism, and the second metal body is connected with an axial reciprocating motion mechanism; the system can simulate the interaction of temperature, load and motion of a first metal body and a second metal body in a lead-bismuth environment, and research the rule of the influence of the interaction on the abradability of the first metal body and the second metal body. In addition, the invention further provides a method for simulating various motions of metal in the lead-bismuth alloy environment, the system is included, and the same beneficial effects can be achieved.

Description

technical field [0001] The invention relates to the technical field of material surface motion abrasion testing, in particular to an abrasion system and method for simulating multiple motions of metals in a lead-bismuth alloy environment. Background technique [0002] Lead-bismuth fast reactor represents one of the six fourth-generation nuclear energy systems in the direction of future nuclear power development. It has a high degree of inherent safety and passive safety, and is conducive to preventing nuclear proliferation. It has a good development prospect in advanced nuclear energy systems. There is flow-induced vibration between the turbulent flow of the coolant and the fuel rods in the lead-bismuth reactor. The flow-induced vibration will cause local wear on the surface of the rods, and the lead-bismuth alloy is corrosive to a certain extent, which will lead to severe fretting abrasion. . The fretting erosion characteristics are very important for core safety analysis....
