Abstract

Galling is a type of wear that affects the oil and gas industry causing loss of profits due to unexpected stops in the exploration and extraction process. In the present work, the galling resistance of four API grade steels (L80 type 1, T95 type 2, P110, and Q125) used in the industry was evaluated by means of cross-cylinder tests. The surfaces were analyzed, and a Galling Tendency number was computed in order to rank the materials. Additionally, tensile and hardness tests were conducted to analyze the influence of the mechanical properties on galling. It was found that P110 exhibited the worst response and T95 the best one. For materials with the same ductility, an increase in strength is associated with higher galling resistance. A new index, based on the ductility and yield strength of the material, is proposed to predict the galling performance, demonstrating a strong correlation with the galling tendency.

API 等级钢的机械性能和抗咬合性能：比较研究

咬合是影响石油和天然气行业的一种磨损，由于勘探和开采过程中的意外停顿而造成利润损失。在本研究中，通过跨缸试验评估了工业中使用的四种 API 等级钢材（L80 1 型、T95 2 型、P110 和 Q125）的抗咬合性能。对表面进行了分析，并计算出了绞合倾向数，以便对材料进行排序。此外，还进行了拉伸和硬度测试，以分析机械性能对咬合的影响。结果发现，P110 的反应最差，而 T95 的反应最好。对于具有相同延展性的材料，强度的增加与更高的抗咬合性相关。根据材料的延展性和屈服强度，提出了一种新的指数来预测咬合性能，该指数与咬合趋势有很强的相关性。

期刊介绍： Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
