The analysis of friction and wear properties of materials at elevated temperatures has become increasingly important, especially for the development and quality control of combustion engine and power plant constituent parts.To meet the resulting need for quantitative data at elevated thermal conditions Anton Paar has extended its range of pin-on-disk tribometers with a . The machine may be used to evaluate the friction and/or fatigue performance of rubber-like materials A compact reciprocating friction and wear tester which has been used extensively in the friction testing of elastomeric materials is described in this paper. Fig 1 is an overall view of the machine showing the basic bench type mounting and . 2.1 Pin-on-Disk Tribometer. The most commonly used configuration for testing materials is the pin-on-disk method in either rotating or linear-reciprocating modes. The corresponding ASTM standards, G99 [] and G133 [], include the measurement of friction coefficient as well as wear rate of the sample and the static partner.The pin-on-disk setup has . The initial decrease in friction in the reciprocating tests on 316L stainless steel, reducing ploughing friction through smoothing of surface asperities, was also observed in 10-cycle nano-scratch tests at 30 mN with a 3.7 μm radius diamond [9] (data converted to friction coefficient in Fig. 9) and in 1 N tests on copper with a 100 μm radius .
