Weight loading ring-piece type corrosive wear tester

Abstract

The invention discloses a weight loading ring-piece type corrosive wear tester, consisting of a stand, a weight loading system, a friction force measuring system, a transmission system and a crucible resistance furnace system. The weight loading system is internally provided with a lifting rotary plate; during loading, the weight tray is located in the low order; during unloading, the lifting rotary plate is rotated; the weight tray is risen to a high-order for bearing a weight; one end of a first wire rope in the weight loading system is horizontally led out and then wound on a pinion of a force-increasing roller; one end of a second wire rope is fixed and then wound on a bull wheel of the force-increasing roller; and the weight is suspended on the sagging end. In the invention, a ringlike sample and a block-like sample are used as the friction pair, liquid metal is used as the corrosive medium, the behavior of the solid friction pair for bearing corrosion and wear at the same time in the liquid metal can be simulated, the load, temperature, rotating speed and liquid metal supply test parameters can be changed, the friction force can be measured and high load-applied accuracy and high measuring precision are ensured.

Description

technical field [0001] The invention relates to a corrosion-wear test device in the field of friction and wear, and more specifically refers to a weight-loaded ring block type corrosion and wear test with liquid metal as the corrosion medium and ring samples and block samples as friction pairs machine. Background technique [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-resistant with a single function. Or the corrosion testing machine, which cannot simulate the behavior of solid friction pairs in liquid metal to withstand corrosion and wear at the same time, the test results obtained have low reference value.

[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
