Wear results were obtained for high contact stress boundary lubricated sliding and advanced bearing simulation testing for wear performance under oil-off operating conditions.
A series of diamond-impregnated specimens (segments) was also produced and tested for wear rate on abrasive sandstone using a special testing rig.
Wholly aromatic thermotropic main chain liquid crystalline copolymers (LCPs) with varying glass transitions (Tg) were tested for wear resistance, particularly under high friction conditions, where surface temperatures can rise.
In view of this, the elastomeric polyurethane Pellethane™ 2363-80A, whish is currently used in non-orthopedic biomedical applications, was tested for wear and its wear rate was found to be much lower than that of UHMWPE, likely due to its ability to conform to the counterface and thus reduce the contact pressure.
Some current ASTM testing standards, notably those on erosion testing, account for the non-linear behavior of wear, but others, such as tests for sliding wear, usually do not.
A new testing method for wear evaluation of polymeric materials for sheet metal forming using a Strip Drawing Test facility is presented and discussed.
Aim of this paper is to develop a new methodology in order to design a representative test specimen for wear damage characterisation in spline couplings.
Further Al-SiCp Composite cams have been tested for accelerated wear at different time intervals.
Also, the fabricated composite materials are tested for its wear properties.
Hydroxyapatite (HA) and composite films of HA and ZrO2 formed on commercial titanium substrates using an organic precursor solution by sol gel route, were tested for fretting wear using a ball-on-flat fretting apparatus.
All samples were cut for wear testing and dielectric testing with the same size of 20 mm × 20 mm and similar average thickness around 2.5 mm.
