摘要

根据控制棒水压驱动机构的使用要求，针对水压缸外套缸碳化钨(WC)涂层采用含钴元素(Co)材料作为粘合剂导致的放射性问题，基于与活塞环摩擦副匹配的摩擦磨损试验，开展了水压缸摩擦副涂层优选研究，提出了碳化铬(Cr3C2)涂层方案，并对Cr3C2涂层性能、水压缸冷态性能进行了试验。结果表明:Cr3C2涂层摩擦系数更低，摩擦磨损性能优于原WC 涂层，涂层性能、水压缸冷态运动阻力及泄漏率等性能与原WC 涂层相当，满足控制棒水压驱动机构的使用要求；且Cr3C2涂层不含Co 元素，解决了原WC 涂层含Co 导致的放射性处理问题。另一方面，Cr3C2涂层无需沉积TiN 膜，简化了水压缸外套缸的摩擦副表面处理工艺。研究结果为控制棒水压驱动机构的整体性能研究以及控制棒水压驱动技术的进一步升级提供了技术储备。

Abstract

According to the use requirements of the control rod hydraulic drive mechanism，aiming at solving the radioactive problem caused by the use of material containing cobalt element (Co) as the adhesive of the tungsten carbide (WC) coating of the outer casing of the hydraulic cylinder， and based on the friction and wear test matching with the piston ring friction pair， the optimal selection study of the coating for the friction pair of the hydraulic cylinder was carried out， the chromium carbide (Cr3C2) coating scheme was proposed， and the performance of Cr3C2 coating as well as the cold state performance of the hydraulic cylinder were tested. Results showed that the Cr3C2 coating had lower friction coefficient and better friction and wear properties than the WC coating， and the coating properties as well as the cold motion resistance and leakage rate of the hydraulic cylinder were equivalent to those in the case of WC coating， which met the use requirements of the control rod hydraulic drive mechanism. Moreover，unlike the WC coating，Cr3C2 coating did not contain Co，so there was no need for a radioactive treatment.Furthermore， the Cr3C2 coating did not need to deposit TiN film， which simplified the surface treatment process of the friction pair of the outer cylinder of the hydraulic cylinder. The research results could provide technical reserves for the overall performance research of control rod hydraulic drive mechanism and the further upgrading of control rod hydraulic drive technology.

Key words： control rod hydraulic drive mechanism; friction pair of hydraulic cylinder; optimal selection of coating materials; friction and wear properties
