The high temperature wear resistance of the coatings was measured using a high temperature pin-on-disc tribometer in the ambient air from 600 °C to 900 °C.
The aim of present study was to evaluate the high temperature wear behavior of aluminum oxide layers at different temperatures by using high temperature pin-on-disc tribo tester and alumina balls as counterfaces.
Experiments were conducted on high-temperature pin-on-disc wear testing equipment.
Dry sliding experiments were conducted on a high-temperature pin-on-disc test rig against polycrystalline alumina at 23 and 400°C up to a sliding distance of 2000 m at 1 m/s.
Wear testing was carried out using a high temperature tribometer (pin-on-disc) with alumina balls as counterparts.
Wear testing was done using a high temperature tribometer (pin-on-disc); the maximum testing temperature was 500 °C in order to prevent significant softening of substrate.
The main objective of this work was to have a detailed analysis of friction and wear properties tested by high temperature tribometer (pin-on-disc) with alumina balls as counterparts in the temperature range of 20 800 °C.
Out of pile tests have been conducted with single fuel pin at high temperature and high pressure, to study the material behavior, to quantify and evaluate the available margin for the PFBR clad tube under various category events.
When the PMMA resist is locally softened, the unbalanced surface tension forces initiate localized material movements until the polymer surface is in a favorable energetic state (e.g. which in high temperature reflow is based on pinning and surface minimization where the surfaces are in equilibrium).
The wear characteristics of the coating were explored on a pin-on-disc high temperature wear tester under 50 300 N at 25 600 °C.
The effectiveness of this new design of high temperature tribological coating was tested using a pin-on-desk tribotester.
