A high-strength platinum material and preparation method for high-temperature deformation resistance

Abstract

The invention relates to a high-strength platinum material used to resist high-temperature deformation and a preparation method. The material is composed of platinum and a strengthening phase, and the strengthening phase is any one of zirconia, yttrium oxide, and titanium carbide particles dispersed in platinum. One and several kinds, the weight percent content of each component of the material is the strengthening phase component>0~≤0.4wt%, platinum is the balance. The material has high strength and excellent deformation resistance, erosion resistance, corrosion resistance and high temperature creep resistance performance under high temperature conditions above 1400 °C in specific environments. Components made of this material have good resistance to high temperature deformation and long service life , can effectively reduce the production cost of the application field.

Description

technical field [0001] The invention belongs to the field of metal materials, in particular to a high-strength platinum material used to resist high-temperature deformation and a preparation method. Background technique [0002] Metal materials that can withstand high temperatures (above 1400°C) and resist deformation are widely used in the industrial field. Platinum material is widely used because of its high melting point, oxidation resistance, corrosion resistance and other excellent properties. Therefore, platinum material is a very advantageous high-temperature metal material, but its high-temperature mechanical properties are poor. In the prior art, the high-temperature mechanical properties of the platinum matrix have been improved to a certain extent by means of solid solution strengthening and internal oxidation strengthening of the second phase particles. The high temperature mechanical properties of the material are not improved enough. With the advancement of ...
