Compared to MoS 2 coatings obtained by magnetron sputtering or ion beam assisted deposition, the MoS 2 bonded solid lubricant coatings has been widely applied in sliding wear due to a cheap technical process and good thickness. However, such coatings technology has been rarely investigated in complex fretting condition. In this work, fretting wear tests of the six novolac epoxy resin...
The tribological behavior of polyetheretherketone (PEEK) filled with nanometer SiC was studied. The composite specimens with different filler proportions were prepared by compression molding. The friction and wear properties of nanometer SiC filled PEEK were investigated on a block-on-ring machine by running a plain carbon steel (AISI 1045 steel) ring against the PEEK composite block. The morphologies...
When silicon nitride slides against itself in water, an extremely low friction coefficient can be obtained by having a suitable running-in condition. This paper focuses of the dynamic running-in process of silicon nitride sliding in water under the conditions of load at 1-3 N, sliding velocity at 30-120 mm s -1 and temperature at 20-80°C with a pin-on-disc apparatus. The results show...
By means of environmental scanning electron microscopy (ESEM), an in situ observation technique was developed to observe the agglomeration process of wear particles of silicon nitride, silicon carbide and alumina and to study the effect of water vapor on the agglomeration of wear particles. The results show that the size of the deposit of wear particles becomes smaller with increasing water vapor...
The temperature and humidity are the most common and important parameters for the practical operation of magnetic tape. In order to develop fundamental understanding of the tribological properties of metal evaporated magnetic tape (MEMT) which is commonly used, microscratch tests of MEMT were carried out.The tests were carried out in an environmentally controlled chamber in which the temperature was...
The tribological behaviour of polyetheretherketone (PEEK) filled with nanometer ZrO 2 was studied. The composite blocks with different filler proportion and particle size were prepared by compression moulding. The friction and wear properties of nanometer ZrO 2 -filled PEEK were investigated under ambient conditions on a block-on-ring machine by running the PEEK composite block against...
The nanometer Si 3 N 4 filled polyetheretherketone (PEEK) composite blocks were prepared by compression molding. The friction and wear properties of nanometer Si 3 N 4 filled PEEK were investigated on a block-on-ring machine by running the PEEK composite block against a plain carbon steel (AISI 1045 steel) ring. The morphologies of the wear traces and the transfer film...
