research on the properties of inside surface of Subsurface Pump barrel by n c o multi elements penetrating
Surface & Coatings Technology, 2007Co-Authors: Hai Zhou, Fei Chen, Bin Yao, Xinbing ZhongAbstract:Abstract Subsurface Pump usually requires good properties of anti-wear and corrosion resistant because it works in a very bad environment. The performance of the oil-well Pump can be distinguishingly improved by intensifying the surface of Pump barrel. This paper study the properties of the inside surface of Subsurface Pump barrel by N–C–O multi-elements penetrating. The modified layer, which is composed of bright layer and transition layer, obtained a thickness of 70 μm at 670 °C, 3 h. The microhardness of the modified layer attains 700 HV. The tribological behavior of the modified layer under dry sliding against steel was evaluated on a ring-on-block test rig. The surface-modified layer showed good friction-reducing and fair anti-wear abilities. Electrochemical corrosion experiment shows that the modified layer further improved the corrosion resistance of Pump barrel.

The distribution of microplastics in the surface layer of the Atlantic Ocean from the subtropics to the equator according to visual analysis.
Marine pollution bulletin, 2020Co-Authors: Ksenia Silvestrova, Natalia StepanovaAbstract:This study reports the levels of plastic contamination in the Atlantic Ocean between 35°N and 32°S during the 1st stage of the 79th cruise of the "Akademik Mstislav Keldysh" from December 12, 2019, to January 4, 2020. A Subsurface Pump system and a Manta net were used for seawater filtration. Twenty-seven samples were visually analyzed with a microscope. It was found that almost every Subsurface sample contained potentially plastic particles, which were classified according to their type and size. Plastic fragments were more commonly found in the samples taken from the surface. In the Subsurface layer, the majority of the detected particles were fibers. These results also indicate that minimal concentrations of plastics tend to be found near the equator and to the north of the Canary Islands. The maximum microplastic concentrations were found in tropical zones. The obtained results are in good agreement with previous models and field studies.
