Spherical Plain Bearing

Experiments were carried out to investigate the tribological properties of spherical plain bearings with copper grid composite liners filled PTFE under two contact pressures(40MPa,60MPa), four oscillating frequencies (1.2Hz, 1.8Hz, 2.4Hz, 3.0Hz) and two swinging conditions. With the help of SEM, EDS and Three-dimensional morphology profiler, the wear mechanism was analyzed. The results indicate the coefficients and wear depths under tilt swinging condition are higher than those of swivel swinging. While the friction temperature show the contrary trend. The research discovers that the friction temperature has a great influence on tribological properties of spherical plain bearings. The analysis demonstrates that the main wear mechanisms are the adhesive and abrasive wear under the two swinging conditions and extrusive wear exist also.

Self Lubricating Composites

This paper summarizes the friction and wear behavior of some fluoride-metal, self-lubricating composites. Fluoride-infiltrated sintered nickel alloy composites and plasma-sprayed, co-deposited fluoride-nickel alloy composites are described. The importance of proper surface-conditioning of the composites is stressed. Performance of fluoride-metal composites in some machine application evaluations is discussed.

Reducing Properties

The friction and wear properties of the DLC coatings were evaluated while being lubricated with pure PAG, PAG containing PN and ZDDP using reciprocating ball-on-disk sliding UMT tester, respectively. The morphologies of the worn surfaces of the DLC coatings were observed using a scanning electron microscope (SEM). The results indicated that the DLC coatings exhibited better tribological properties under the lubrication of PAG containing PN or ZDDP than that of pure PAG. In addition, PN and ZDDP as additives show different tribological properties. The former offers better anti-wear ability, the latter offers better friction-reducing properties.

The effects of acrylamide modified liner on bonding properties and tribological properties of self-lubricating spherical plain bearings were explored by used of Instron5944 electronic universal testing machine and homemade spherical plain bearings friction and wear tester. The results showed that the bonding properties of bearings modified by acrylamide modified liner were much more improved than those of the unmodified bearings; Self-lubricating spherical plain bearing friction and wear properties and oscillating frequency obvious correlational dependence. With the increase of the oscillation frequency, the friction coefficient and the wear loss increased, while the friction temperature rose. The friction coefficient, wear loss and friction temperature of bearings modified were much more improved than those of the unmodified bearings. It showed that the liners after modification treatment can improve the tribological properties of self-lubricating spherical plain bearings.

In the present work, SiC was pressureless solid state sintered with 3 wt% C and 0.6 wt% B4C as sintering additives. The friction and wear behavior of the PSSS SiC ceramics was investigated by using a block-on-ring tribometer. The wear volume and friction coefficient was measured. It is as expected that the friction coefficient increased with the elevation of the normal load and sliding speed. The microstructure of the worn surface was observed, based on which the wear mechanism was analyzed. Different degrees of oxidation during the friction process was found and the degree of oxidation was related to the severity of wear. The normal load was found to exert great influence on the wear of the SSiC ceramics.

The tribological properties of Fe–Cr–B alloys were studied sliding against SiC ball in liquid paraffin oil. The boron played an important role in improving tribological properties of alloys. The friction coefficients of alloys decreased with the increase of normal load and sliding speed. The Fe–Cr–B alloys showed better wear resistance than that of Fe–Cr alloy. Fe-21 wt.% Cr-7 wt.% B alloy had the best tribological properties. The wear mechanism of Fe–Cr alloy was abrasive wear and plastic deformation. The wear mechanism of Fe–Cr–B alloys was microploughing and fatigue flaking pits.
