    It is widely recognized that hydrogen atoms adsorbed at steel surface permeate into the steel in rolling contact to reduce rolling contact fatigue life. Oxide film on steel surface may influence the permeation properties of hydrogen. However, how the surface film prevents or promotes hydrogen permeation is yet to be studied for the purpose of finding an effective way to prevent hydrogen permeation and early occurrence of spalling failure. This paper describes a study to explore the effects of temperature on the formation of oxide film and fatigue life in hydrogen, argon and air. Rolling contact fatigue tests are conducted at 333 K and 363 K by using a three-ball-on-disk type apparatus. The rolling contact fatigue life in hydrogen was shorter than that in argon, and life in air was the longest. Relationship was found between fatigue life and hydrogen concentration in steel. Also, it was found that iron oxide grew to larger grain size in the surface layer in hydrogen environment, which may result in shorter fatigue life. Finally, fatigue failure on ball surface which frequently occurs in hydrogen at 363 K is discussed.

    <p>Alkyl diphenyl ether, ADE, synthetic lubricant oil is often used in severe lubrication conditions by its high oxidation stability and lubrication properties. In this study, pure rolling and rolling-sliding contact fatigue test was conducted lubricated with ADE’s. Poly alpha olefin, PAO was also used as reference lubricant. Some polyphenyl ethers were added to ADE to know the effects of polarity of ether group under severe rolling contact condition. In pure rolling condition at 150°C in nitrogen, ADE showed higher fatigue life than PAO. The bearing life was extended further by polyphenyl ether additives. ADE and ADE with polyphenyl ether oils formed carbon rich surface film on the rolling track during the rolling contact fatigue test. ADE also showed a higher bearing life than PAO under rolling-sliding contact. Traction force and wear was slightly higher with ADE than PAO in a higher slip range.</p>

    <p>Rolling contact fatigue, RCF, of steel under lubrication with alkyl diphenyl ether, ADE, and poly alpha olefin, PAO, in three environmental gas conditions was studied. RCF tests were conducted at 150°C with ball and disk configuration, and hydrogen concentration in steel, chemical changes of oils and rolling surfaces were analyzed after the tests. In order to confirm basic oil properties, such as viscosity-pressure coefficient of oil under contact condition, film thicknesses under pure rolling contact were also measured by interferometry method with using ball on disk type tribo tester. ADE had greater RCF life in nitrogen than PAO with the same viscosity. This was caused by ADE’s higher viscosity-pressure coefficient, carbon-rich surface film formation and higher chemical stability to decompose and to generate hydrogen on nascent steel surface. On the other hand, in air, ADE also showed greater RCF life than PAO. This was ascribed to higher anti-oxidation stability of ADE.</p>

  • Tribochemistry of Transfer Layer Evolution during Friction in HiPIMS W-C and W-C:H Coatings in Humid Oxidizing and Dry Inert Atmospheres Reviewed International coauthorship International journal

    The experimental and theoretical investigations of transfer layers in the dry sliding contacts between steel ball and HiPIMS W-C and W-C:H coatings were performed in humid air, dry nitrogen, hydrogen and vacuum on a series of coatings with different contents of carbon and hydrogen in the matrix. Transfer layers formed on the ball in all friction tests, but their composition varied depending on the environment. In humid air, the mechano(tribo)chemical reactions necessary for the obtained phases involved oxidation of WC and Fe, water vapor decomposition and hydrogenation of carbon. Modeling indicated that humidity enhanced oxidation and carbon hydrogenation. In nitrogen, WC decomposition generating carbon was dominant, whereas, in hydrogen, it was carbon hydrogenation. In vacuum, WC decomposition producing W was found to be responsible for high coefficients of friction (COFs). COFs approaching superlubricity were obtained in the H2 atmosphere in the coatings with sufficiently high matrix C:H content. COFs seem to be controlled by the ratio of hydrogenated carbon and oxide phases in transfer layer, which depends on the reactions possible in the surrounding atmosphere.

    The modelling of simultaneous chemical reactions in complex systems was successfully applied to mechano(tribo)chemical reactions during friction between steel ball and High Power Impulse Magnetron Sputtered (HiPIMS) W-C:H coatings in humid air, dry nitrogen, hydrogen and in vacuum. The main mechano(tribo)chemical reactions leading to transfer layer formation in humid air - oxidation of WC and Fe, water vapor decomposition and carbon hydrogenation - were confirmed. In nitrogen, the decomposition of WC producing carbon was predicted. The prediction in hydrogen was only the formation of methane. In vacuum, the decomposition of WC and FeOWO3 into W and Fe and CO formation were dominant. Thus, the friction is controlled via amount of hydrogenated carbon resulting from the dominant mechano(tribo)chemical reactions.
