Embodiment 1

[0030] Example 1 Test equipment for evaluating uniform corrosion of metallic materials

[0031] Refer to attached Figure 1-5 , the suspension-type test equipment for evaluating the uniform corrosion of metal materials in this embodiment is composed of the following systems and devices: data control system 1, suspension system 2, temperature control system 3 and circulation system 4.

[0032] Wherein, the suspension system 2 includes a ceramic chamber 2-1, a chamber support 2-2 for supporting the chamber 2-1, an intermediate frequency AC power supply 2-3, a coil and a weighing device. Wherein the coil includes a stable coil 2-4 and a suspension coil 2-5, and the coil is a copper wire 2-13 wrapped with a coil insulating layer 2-6; the weighing device includes an electronic balance 2-11, a support 2-8, and is arranged on the support The horizontal telescopic knob 2-9 on the 2-8 and the vertical telescopic knob 2-10 and the horizontal tray 2-7.

[0033] Specifically, in this em...

Embodiment 2

[0041] Embodiment 2 test method

[0042] The test method of the present embodiment is based on the test equipment in embodiment 1, specifically comprises the following steps:

[0043] 1) Prepare the sample 5 to be tested, and place the sample 5 to be tested on the tray 2-7.

[0044] 2) Adjust the bracket, adjust the horizontal telescopic knob 2-9 and the vertical telescopic knob 2-10 so that the sample 5 to be tested is located in the middle position between the suspension coil 2-5 and the stable coil 2-4, which is convenient for subsequent stable suspended.

[0045] 3) The electronic balance 2-11 sends the weight data applied to the pallet 2-7 by the sample 5 to be tested to the control system 1, and the control system 1 adjusts the size of the power supply 2-3 according to the received weight data to control the sample to be tested. 5 is gradually separated from the tray 2-7, and the test sample 5 is finally suspended between the suspension coil 2-5 and the stabilization c...

Abstract

The invention discloses test equipment for evaluating uniform corrosion of a metal material, which comprises a suspension system and a control system, wherein the suspension system comprises a coil and a power supply for supplying power to the coil, the control system is used for controlling and adjusting the power supply, and the coil is used for suspending a sample to be tested after being electrified. The test equipment for evaluating the uniform corrosion of the metal material is reasonable in structural design, and the coil is electrified to generate upward magnetic force, so that the to-be-tested sample can overcome gravity to suspend. The frequency of the power supply is adjusted through the control device, and the magnitude of the magnetic force generated by the coil is controlled,so that the to-be-tested sample can suspend stably, unnecessary non-uniform corrosion caused by contact of the metal material in the soaking process is completely avoided, and the accuracy and scientificity of evaluation of the uniform corrosion performance of the material are improved.

Description

technical field [0001] The invention belongs to the technical field of metal material detection, and in particular relates to a test equipment for evaluating uniform corrosion of metal materials and a test method for uniform corrosion of metal materials using the test equipment. Background technique [0002] Corrosion refers to the physical-chemical interaction between the metal and the environment, resulting in changes in the properties of the metal, and often leads to damage to the function of the metal, the environment or the technical system composed of them. In industrial production, there are often problems such as failure of equipment and components due to corrosion of metal materials, which poses a serious threat to production safety. Metal corrosion is generally divided into uniform corrosion and localized corrosion. Among them, uniform corrosion is the most common form of corrosion. Evaluating the uniform corrosion resistance of materials has important guiding sign...
