Experimental Study on Water-Lubricated Bearing Material in Deep Sea Space Station

Abstract

With the deepening of marine development activities, human-related sea-related behavior has gradually moved from shallow sea to deep sea. In this paper, the deep sea environment of the thruster bearing of the deep sea space station is characterized by high pressure, high corrosion, large amount of microorganisms and sediment. The Modified UHMWPE is developed, and the friction under simulated seawater conditions is studied by using different proportions of samples. The experimental results show that the materials developed in this study have lower friction coefficient and better wear resistance than Thordon and Feroform materials, and are very suitable for deep sea environment.
