Problems solved by technology

[0003] At present, the most commonly used tool for placing samples is tweezers. Use tweezers to clamp one end of the sample and gently place it in a glass container. Scratches will affect the observation after the test; second, in the process of using the tweezers, it all depends on the strength of the hands of the tester. If the sample is large, the hand is slightly loose, or the tip of the tweezers is slippery, the sample will fall. The solution may be splashed with water, the corrosive solution will burst out, and splash on the test personnel, causing injury; or a certain corner of the sample may be directly hit on the glass container, which will break the container, causing the corrosive solution to be left and eroded. There are also dangers when the equipment and test benches are cleaned up by the test personnel

Embodiment Construction

[0016] This embodiment provides a method for placing samples in a safe intergranular corrosion test, wherein the structures of the sliding channel and the supporting plate are as follows: Figure 1-2 shown.

[0017] The sliding passage includes a first handle 1 and a slideway 2 , the slideway 2 is square or cylindrical, adopts a hollow structure with both ends open and is fixed at the bottom of the first handle 1 . The supporting plate includes a second handle 3 and a supporting plate 4 , the supporting plate 4 has the same width as the outer edge of the slideway 2 , is L-shaped and is fixed on the bottom of the second handle 3 . The first handle 1 is exactly the same as the second handle 3, and the shape adopts a slender rod shape. When in use, the supporting plate 4 blocks the bottom of the slideway 2, and the fixing member 5 is used to fix the first handle 1 and the second handle 3 together; the material of the sliding channel and the supporting plate is inert to the test ...

Abstract

The invention discloses a method for placing a sample in a safe intergranular corrosion test, and relates to the technical field of intergranular corrosion tests. When the sample is placed, the sampleis first placed in an auxiliary support, a tester puts the auxiliary support and the sample together into a glass container, then the sample is slowly placed in the container, and finally the auxiliary support is taken out. The method is simple and effective, and the safety of the test is greatly improved.

Description

technical field [0001] The invention relates to the technical field of intergranular corrosion tests, in particular to a method for safely putting samples into intergranular corrosion tests. Background technique [0002] GB / T 4334 is the standard for testing intergranular corrosion of stainless steel, and GB / T15260 is the standard for testing methods for testing nickel-based alloys for intergranular corrosion. Among these two standards, the sulfuric acid-copper sulfate test method is a relatively commonly used test method. The sample size of these two test methods is relatively large, both are about (80-100) mm × 20mm, and they are both in the test. The sample is placed in the boiling test solution, and the test solution is a corrosive solution, and there is a potential danger in the process of placing the sample. [0003] At present, the most commonly used tool for placing samples is tweezers. Use tweezers to clamp one end of the sample and gently place it in a glass conta...
