2.3 Tribological test The tribological tests were performed on a reciprocating friction and wear monitor test rig (TR-281M-M6) for a cylinder liner and piston ring as shown in figure 1. Piston ring is movable and slide on the surface of cylinder liner which is stationary. A bottom heating unit is used to heat the friction pair. Approximately 2drops
range of mechanisms, including reciprocating engines and pumps (Mccarthy 2018). The principle of operation of a linear reciprocating tribometer consists of sliding test samples against a stationary counter surface under load and recording the parameters of interest (Mohan et al. 2009). With this tribometer, it will be possible to measure friction

To facilitate the in-depth study of the tribological behavior of texture friction pairs in the process of reciprocating friction. The micro-displacement deformation output model of compliant mechanism is deduced using a new method for indirectly measuring friction coefficient through micro-deformation of double parallel four-bar compliant mechanism. Then, the whole structure .
Friction coefficient and sliding speed under 150 N load According to a general overview of the results as test conditions (time, speed, and load) and a high coefficient of friction considered to be obtained, though reciprocating friction test apparatus has a small oil tank, boundary lubrication and/or mixed lubrication regimes. In the pin-dish sliding wear test, at room temperature, under 20 N test, the friction coefficient of the sample with rough lamination/smooth lamination/resin carbon is 0.13 and the mass wear loss .

Comparative study on sliding friction and wear properties of low alloy wear-resistant steel Hardox400 and NM400 at room temperature using Retc multi-function friction and wear tester.Historical/Traditional Test Geometry. The classic work of Thurston 1, Martens 2, Stribeck 3 and Hersey 4 were done using a journal-bearing geometry, which possesses all of the above requirements (Figure 3). An instrumented journal-bearing test allows for evaluation of the friction over a range of relative velocities and/or loads.The Japanese test standard is 100 times of reciprocating friction, while other reciprocating friction is only 10 times, which is a huge difference. Therefore, the total contact area and the total course of the Japanese standard friction test should be long, so the friction colour fastness test results are the worst, and the test method is the .
Integrating the capability for high cycle, long duration reciprocating nano-/micro-scale tests into a commercial instrument extends the versatility of the multi-functional test instrumentation.
