Abstract
Over the years, polymeric composites have been produced to compete favourably with metals towards addressing the problems of corrosion in the oil and gas industry. For the first time, the tribological behaviour, at different normal load conditions, of coir–coconut husk particulate-reinforced polymer composites subjected to a simulated acidic environment of pH 2.2 for a period of 3, 6 and 9 days was elucidated. Gradients in tribological characteristics (coefficient of friction and wear tracks) were noticed for all samples at the processing conditions. The experiments revealed that with an increase in the load conditions on the tribo-machine, the acid-aged samples immersed for 3 days (3PA) showed distinct gradients in the coefficient of friction. Complementarily, the wear track of sample 3PA showed no clear path that supports the aforementioned mechanism.
多年来，在解决石油和天然气行业的腐蚀问题方面，聚合物复合材料已经被生产出来，与金属相竞争。本文首次研究了椰壳颗粒增强聚合物复合材料在pH为2.2的模拟酸性环境下3天、6天和9天的摩擦磨损性能。在加工条件下，所有样品的摩擦学特性（摩擦系数和磨损轨迹）都有梯度。实验结果表明，随着摩擦机加载条件的增加，酸龄3 d （3PA）试样的摩擦系数呈现明显的梯度变化。另外，样品3PA的磨损轨迹没有明确的路径支持上述机制。
期刊介绍：
"Polymer Bulletin" is a comprehensive academic journal on polymer science founded in 1988. It was founded under the initiative of the late Mr. Wang Baoren, a famous Chinese chemist and educator. This journal is co-sponsored by the Chinese Chemical Society, the Institute of Chemistry, and the Chinese Academy of Sciences and is supervised by the China Association for Science and Technology. It is a core journal and is publicly distributed at home and abroad.
"Polymer Bulletin" is a monthly magazine with multiple columns, including a project application guide, outlook, review, research papers, highlight reviews, polymer education and teaching, information sharing, interviews, polymer science popularization, etc. The journal is included in the CSCD Chinese Science Citation Database. It serves as the source journal for Chinese scientific and technological paper statistics and the source journal of Peking University's "Overview of Chinese Core Journals."
