抽油泵泵筒表面硬化技术

Surface Hardening Technique for Pump Unit's Working Barrel

叙述了抽油泵泵筒表面硬化技术的工艺原理。介绍了泵筒表面使用渗碳、氮化、碳氮共渗、镀铬、激光相变硬化、化学镀镍工艺等方法所获得的表面硬化层的机械性能和基本参数。为抽油泵的选择、使用和维修提供参考。

This article shows the principle of surface harden-ing technique for pump unit's working barrel, in-troduces the mechanical performance and basic pa-rameters of the surface hardening layer gained byuse of carburizing,nitride,co-nitriding and carbur-izing, chromium plating,laser phase-changing hard-ening and chemical nickel plating etc.
