Abstract: Research advances and application examples of surface treatment technologies such as infiltration layer, micro-arc oxidation, chemical vapor deposition, and thermal spraying to improve the comprehensive properties of tantalum metal, reduce the failure behavior of tantalum materials, and enhance the service life of tantalum equipment were summarized. Finally, the development direction of surface reinforcement treatment for tantalum materials was discussed.

Key words: tantalum, rare metal, surface treatment, comprehensive property improvement, service lifetime
