Embodiment Construction

[0023] The present invention will be further described below by means of the accompanying drawings and specific embodiments.

[0024] Various reagents and materials used in the embodiment meet the following requirements respectively:

[0025] Gasoline for parts cleaning complies with GB 17930-2011 / XG1-2012 standard;

[0026] Acetone for parts cleaning complies with GB / T 6026-1998 standard;

[0027] High-purity argon gas (purity ≥ 99.99%) for hot isostatic pressing medium complies with GB / T4842-1995 standard;

[0028] The processed workpieces are copper chromium zirconium and 316L stainless steel plates.

[0029] The specific steps of this method are as follows: figure 1 as shown,

[0030] (1) The connection interface between copper, chromium, zirconium and stainless steel needs to be polished first, and the oil on the surface of the workpiece should be removed with gasoline, then cleaned with acetone organic solvent, and dried with argon;

[0031] The purpose of this is t...

Abstract

The invention belongs to a dissimilar metal diffusion bonding processing technology, and specifically discloses a hot isostatic pressure diffusion bonding method of a copper chromium zirconium-stainless steel composite plate. A plate junction surface is polished and cleaned, and then the plate junction surface is wrapped and sleeved with a vacuum seal and fixed to a hot isostatic press; and the plate junction surface is subjected to pressurization, heating and pressurization, heat and pressure preservation, furnace cooling and solution treatment; and various problems in a traditional connection mode are solved, the connection performance between dissimilar metals are stable, defects of the connection interface are obviously reduced, and the product yield is significantly improved. The mechanical properties and the organization structure of a composite plate connected by hot isostatic pressure diffusion can meet the relevant requirements of fusion test reactor products.

Description

technical field [0001] The invention belongs to dissimilar metal diffusion connection treatment technology, in particular to a hot isostatic pressure diffusion connection method of copper chromium zirconium-stainless steel composite plate. Background technique [0002] Copper-chromium-zirconium-stainless steel composite plates are widely used in the preparation of ITER first wall parts, and will occupy an important place in the future fusion reactor materials. However, the traditional manufacturing process of composite plates faces many problems: the connection performance is not stable enough, the connection There are defects in the interface, the traditional explosive welding connection process has strict requirements on the process implementation conditions and the product yield is not high. Contents of the invention [0003] The purpose of the present invention is to provide a hot isostatic pressure diffusion connection method for copper-chromium-zirconium-stainless st...
