Abstract

The invention belongs to the technical field of metal material surface processing, and relates to a Cr-Si-Zr-B penetrant and an application method thereof to the surface of tantalum and tantalum alloy. The Cr-Si-Zr-B penetrant is prepared from the components in percentage by weight: 8%-10% of Cr powder, 6%-8% of Si powder, 2%-3% of Zr powder, 1.2%-1.5% of B powder, 5%-6% of NaF powder, 1%-2% of NH4Cl powder and the balance of Al2O3 powder; and the application method of the Cr-Si-Zr-B penetrant to the surface of the tantalum and tantalum alloy includes the steps that 1, surface nanocrystallization treatment is performed on samples or workpieces of the tantalum and tantalum alloy; and 2, a Cr-Si-Zr-B coating is prepared by a pack cementation method. The thermal protection performance of thetantalum and tantalum alloy is improved, the obtained coating is good in bonding force, the structure is uniform and dense, the technology is simple, the process is stable, the operation is convenient, the processing efficiency is high, the cost is low, and realization is easy.

Description

technical field [0001] The invention belongs to the technical field of metal material surface processing, and relates to a Cr-Si-Zr-B penetration agent and an application method thereof on the surface of tantalum and tantalum alloys. Background technique [0002] Due to their high melting point, high density, super corrosion resistance, good high temperature strength and machinability, tantalum and tantalum alloys have become candidate materials for high temperature structures in aerospace, shipbuilding and other fields. However, the high-temperature thermal protection properties of tantalum and tantalum alloys are mainly due to their extremely poor oxidation resistance, which seriously restricts their production and application. Therefore, improving the high-temperature thermal protection performance of tantalum and tantalum alloys is an urgent task for solving tantalum alloys as high-temperature structural materials. [0003] At present, the methods to improve the high te...
