Abstract
The wear and corrosion resistance of water-based polytetrafluoroethylene (PTFE) coating need to be further improved to cope with various harsh environmental conditions. In this paper, a mulberry-like ZSM-5 molecular sieve was prepared and then was modified to enhance the uniformity, wear resistance and hardness of PTFE coating. In addition, a ZSM-5/MoS2/PTFE coating was developed by adding MoS2in the chemical composition of coatings, which significantly increased the critical cracking thickness of PTFE to 27μm. The wear amount of ZSM-5/MoS2/PTFE coating is only 5.7 mg, and after 680 h of salt spray, there is no obvious corrosion on the surface. The friction coefficients under applied loads of 5 N, 10 N, and 20 N are 0.007, 0.057, and 0.055, respectively. The experiment results show that the coating possesses excellent lubrication, wear resistance, and corrosion resistance, and its performance and cost are far superior to commercial products.
期刊介绍：
The journal aims to publish papers at the forefront of nanoscale science and technology and especially those of an interdisciplinary nature. Here, nanotechnology is taken to include the ability to individually address, control, and modify structures, materials and devices with nanometre precision, and the synthesis of such structures into systems of micro- and macroscopic dimensions such as MEMS based devices. It encompasses the understanding of the fundamental physics, chemistry, biology and technology of nanometre-scale objects and how such objects can be used in the areas of computation, sensors, nanostructured materials and nano-biotechnology.
