Abstract:

Titanium alloys are known for their strong chemical reactivity with surrounding gas due to their high chemical affinity, especially in dry machining. But it is very difficult to study the influence of surrounding gas on the tool-workpiece interface because of the machining processes’ complexity. In this paper, rotating pin-on-disc friction tests have been carried out at room temperature in ambient air and nitrogen gas to investigate the friction and wear behavior of WC-Co cemented carbide sliding against Ti6Al4V alloy.

Abstract:

The pin-on-disk tester is a method used for investigating wear. The sliding mechanism between the pin and the disc experimentally creates wear. In this paper, the wear characteristics of an aluminium pin sliding on an SKD11 disc lubricated with double fraction palm olein were investigated. The pin was made from pure aluminum A1100. The results were compared with those of tests in which the disc was lubricated with commercial hydraulic oil. In both sets of experimental conditions, the normal load varied from 4 to 10 kg. Rotational speed was set to 1200 rpm. From this study, it was found that di

A systematic study comparing the wear behaviour of composites with nylon matrix (PA66, PA46, PA12) and different nanoadditives and reinforcing additives (graphite, graphene, MoS2 and ZrO2) has been carried out in order to achieve a proper self-lubricant material for bearing cages. The wear characterisation was done using pin-on-disc tests, SEM and EDX analysis. The results show that better outcomes are obtained for composites based on PA12. The addition of ZrO2 offers negative values of wear due to the metallic particle transference from the counterface to the polymeric pin.

Abstract:

Although tribological tests on polymers are traditionally performed on small-scale pin-on-disc or bloc-on-ring configurations, present sliding tests under high load provide more accurate de-sign data. For wear tests on large samples edge effects, stress concentrations and the moveability of wear debris into the contact zone are simulated close to practice. It is illustrated that friction is gene-rally lower compared to small-scale tests, while overload and deformation occur more frequently.

Abstract:

Brake wear has been identified to be an important source of non-exhaust emissions in transportation. The high dissipated energy in the contact not only results in large frictional heat dissipation in the brake components but also in the generation of debris, particles and gases produced by the wear of both pads and disc. Numerical simulation or tribological tests at the material scale are still not sufficient to predict wear. Experiments at the original scale of the brake system are necessary, with a significant implementation time, high costs and with a limited scope. The aim of the present w

Abstract:

This study investigates the influence of temperature and load on the dry sliding property of interface between brake friction material with low metallic formulation and gray cast iron disc. Full factorial design was employed to conduct pin-on-disc wear tests to attain wear and friction response under external heating temperature and applied load ranging from 25-175°C and 50-500N(0.35-3.5MPa), respectively. The analysis of experiment results shows the effect of load on wear rate is almost linear. Wear rate exhibits an increase followed by decrease trend with applied load. Friction coefficient i

Pin-on-disc tribological tests were performed on Si3N4/SiC/graphite ceramic composites with 5N applied load, at room temperature in dry conditions. Tests were completed with microhardness tests (F=10N), indentation fracture toughness tests (F=100N), furthermore morphological analyses of the wear tracks by SEM. Based on SEM pictures of the wear traces the main damage mechanism could be identified as an abrasive wear. The purpose of the paper is to model the abrasive wear of the given composites. For this reason lateral crack chipping model suggested by Evans and Marshall for Si3N4 ceramics was

Abstract:

The paper is focused on the wear mechanism of orbital forged and equal-channel angular extruded Cu OFHC (oxygen-free high thermal conductivity) material. The wear behaviour of the Cu OFHC material is investigated through pin-on-disc tests. Two different processing conditions have been used, equal-channel angular processing (ECAP) and orbital (radial) forging. The wear investigations in this orbital formed material are unique; additionally wear properties show interesting wear characteristics. Particular attention has also been paid to the friction coefficient and to the role of the wear rate.

Abstract:

Electrostatic charge sensing technology has been used to monitor adhesive wear in oil lubricated contacts. Previous work in this area demonstrated that “precursor” charge events may be detected prior to the onset of scuffing. Possible charging mechanisms associated with the precursor events were identified as tribocharging, surface charge variation, exo-emissions and debris generation. This paper discusses the proposed charging mechanisms and details a series of investigative tests using an adapted pin-on-disc (PoD) rig. The PoD tests focused on surface charge variation effects and were of two

The friction and wear tests of high-speed railway braking materials for a variety of braking speeds (600, 400, and 200 rad/min) at 65% and 98% RH RH (RH: relative humidity) were carried out utilizing a friction-testing machine and humidity generator. The research results indicate that braking speeds and ambient humidity have a prominent influence on the friction and wear characteristics of high-speed railway braking materials. At 65% and 98% RH, the lower the braking speed, the lower the wear rate, and the better the wear resistance property of the braking material. Furthermore, at 600 rad/min
