为改善P110石油套管钢的性能，提高其使用寿命，采用固体渗铬法在P110石油套管钢表面制备渗铬层。采用扫描电镜（SEM）、X射线衍射仪（XRD）、辉光放电发射光谱仪（GDOES）和显微硬度计对涂层的表面形貌、截面组织、相组成、元素分布和显微硬度分布进行了研究。采用球盘式摩擦磨损试验机，研究了P110钢和渗铬层在干、湿摩擦条件下的摩擦磨损性能。系统地研究和分析了试样的摩擦系数、质量损失和表面形貌的变化规律。利用能谱仪（EDS）和扫描电镜（SEM）分析了试样的磨损机理。结果表明，所制备的涂层均匀致密，主要由MxCy2组成，厚度可达55μm。与P110钢相比，渗铬层具有更高的表面硬度和更低的质量损失。与GCr15摩擦副摩擦时，渗铬层的减摩效果不明显，而与Si3N4摩擦副摩擦时，渗铬层表现出一定的减摩性能。在滑动磨损试验中，不同表面硬度和表面成分的试样表现出不同的磨损机理。渗铬处理使P110钢的工作表面具有更高的表面硬度和耐磨性。
Chromizing coating was fabricated on P110 oil casing tube steel by employ of pack cementation to improve the performance and increase the life-time during operation. Scanning electron microscope (SEM), X-ray diffraction (XRD), glow discharge optical emission spectroscope (GDOES) and microhardness tester were used to investigate the surface morphology, cross-sectional microstructure, phase constitutions, element distribution and microhardness distribution of the coating. Friction and wear behaviors of P110 steel and chromizing coating were measured using a ball-on-disc type tribometer under sliding against two counterparts in dry and wet conditions. The variations in friction coefficient, mass loss and surface morphologies of the tested samples were systemically investigated and analyzed. Energy dispersive spectrometer (EDS) and SEM were employed to elucidate the wear mechanisms of the tested samples. The results showed that the obtained coating was uniform and compact, mainly consisted of MxCyand reached a thickness of 55μm. Chromizing coating had higher surface hardness and lower mass losses than that of P110 steel. When sliding against GCr15, chromizing coating showed no obvious friction–reduction effect, but indicated certain anti-friction property in sliding against Si3N4. The tested samples varied with surface hardness values and surface compositions have shown different wear mechanisms in the sliding tests. Chromizing treatment makes it possible to create on the working surface of P110 steel with enhanced surface hardness and wear resistance.
