Abstract

The invention discloses a bolt loading ring-block type corrosive wear testing machine. The testing machine comprises a frame, a bolt loading system, a friction measuring system, a transmission system and a crucible electric resistance furnace system, wherein the loading bolt in the bolt loading system is arranged on a hanger bearing connection component, a loading rod is fixedly connected with a positive pressure loading main force hinge base; and a pressure sensor in the friction measuring system is fixed on the frame, and a sample block is arranged on the lower part of the loading rod to press an annular sample. The loading bolt of the testing machine is tightened to apply a load and withstand a force sensor, the positive pressure loading main force hinge base and the loading rod are used to amplify the load. The testing machine uses the annular sample and the sample block as the friction pair and uses liquid metal as the corrosion medium, and can stimulate the corrosion and wear behaviors of the solid friction pair in liquid metal, change the test parameters of load, temperature, rotate speed and the supply of liquid metal and measure the friction; and the load is applied accurately and the measurement accuracy is high.

[0002] The solid friction pair in the liquid metal is subject to friction and wear on the one hand, and is corroded by the liquid metal on the other hand. The interaction between the two makes the damage of the material more severe. However, most of the existing material testing machines are wear with a single function. Or the corrosion testing machine, which cannot simulate the behavior of solid friction pairs undergoing corrosion and wear in liquid metal at the same time, the reference value of the obtained test results is low

[0003] ZL98219097.2 discloses an abrasion testing machine, which can simulate the behavior of a solid friction pair undergoing corrosion and wear simultaneously in a liquid metal medium, but its sample clamping rod is right-angled, and the horizontal side is installed in the guide groove Inside, the guide groove must have very good lubrication to ensure that the error of the loading force is small

At the same time, the abrasion testing machine has no friction measuring device, so it is impossible to obtain the friction coefficient that characterizes the wear resistance of the material
