Corrosion resistance enhancement strategy of silver platinum electrode paste in electrochemical environment

Silver platinum electrode paste, as an important functional material, plays an indispensable role in fuel cells, sensors, and various electrochemical devices. However, due to its working environment typically being in strongly acidic or alkaline solutions, it faces serious corrosion risks. In order to ensure the long-term stable operation of these devices and improve their work efficiency and lifespan, it is particularly important to study how to enhance the corrosion resistance of silver platinum electrode paste. This article will explore several effective methods for enhancing corrosion resistance and introduce the brands under Advanced Institute (Shenzhen) Technology Co., Ltd——Research Platinum Brand YB8301 Silver Platinum Electrode PasteThe research achievements made in this area.

Composition and Characteristics of Electrode Slurry

The silver platinum electrode paste is mainly composed of precious metal powders (such as silver and platinum), organic carriers, and other additives. Among them, precious metals provide excellent conductivity and catalytic activity, while organic carriers are responsible for endowing the slurry with good coating properties and mechanical strength after sintering. In addition, the appropriate addition of additives can help improve the rheological properties of the slurry and the surface quality of the final product.

Corrosion resistance enhancement mechanism

Surface Modification Treatment

By appropriately modifying the surface of silver platinum particles, the corrosion resistance of the material can be significantly improved without affecting its intrinsic properties. For example, the use of chemical coating technology can form a uniform and dense protective film on the metal surface, preventing external media from directly contacting the substrate; Alternatively, nanoscale oxide coatings can be introduced using methods such as physical vapor deposition (PVD) to increase the barrier effect at the interface and reduce the number of defects on the ion migration path.

Alloying design

Adjusting the proportion of silver platinum alloy appropriately is also an effective way to improve corrosion resistance. Research has shown that binary or multi-component alloy systems at specific ratios often exhibit better stability than pure metals. This is because the interaction between atoms inside the alloy changes the electronic structure, reduces the local potential difference, and thus suppresses the occurrence and development of pitting corrosion. For certain special application scenarios, it is also possible to consider adding a third element (such as palladium, ruthenium, etc.) to further optimize the overall performance.

Structural optimization

In addition to component regulation, reasonable microstructure design cannot be ignored. By controlling the sintering temperature and time parameters, a tighter connection can be established between silver platinum particles, forming a three-dimensional network like conductive pathway while enhancing the overall density of the structure. In this way, it ensures good conductivity continuity and reduces potential corrosion sensitive areas. In addition, the use of porous structure design can promote gas diffusion process, facilitate timely discharge of reaction products, and prevent local pH value changes caused by accumulation, thereby accelerating the corrosion process.
