摘　　要：加氢裂化工艺是石油炼制中的重要技术,通过在高温高压下利用催化剂和氢气处理重质油,生产出高附加值的轻质油产品。由于氢渗透会对变送器的性能产生影响,因此选用合适的隔膜涂层至关重要。研究表明,金和金合金涂层在抗氢渗透方面表现突出,能够有效防止氢气扩散,延长设备的使用寿命并提高工艺的稳定性。这些涂层材料在高温高压环境下,仍保持良好的抗腐蚀性能和机械稳定性,是防氢型变送器的理想选择,特别适用于加氢裂化等复杂工况。The hydrocracking process is a critical technique in oil refining,producing high-value light oil products by treating heavy oil under high temperature and pressure with catalysts and hydrogen.Hydrogen permeation can negatively impact the performance of transmitters,making the selection of suitable diaphragm coatings crucial.Research shows that gold and gold alloy coatings exhibit excellent hydrogen resistance,effectively preventing hydrogen diffusion and extending equipment lifespan while improving process stability.These coatings maintain outstanding corrosion resistance and mechanical stability under high-temperature,high-pressure conditions,making them ideal for anti-hydrogen transmitters,especially in complex hydrocracking environments.
