“…According to the Archard wear equation, the wear rate ( W R ) of the counterpart ball was calculated using the following formula:

W_{R} = V / F_{n} \times L

where W R is the wear rate per unit load and per unit distance, F n (N) was the applied load, L (mm) is the sliding distance, and the wear volume of the ball V (mm 3 ) was calculated with the following formula:

V = π h (3 r^{2} + h^{2}) / 6

The tribological behaviors of silicon nitride (Si3N4) sliding against sintered polycrystalline diamond (PCD) were investigated by varying the relative humidity (RH) in the testing atmosphere. The results indicated that higher RH corresponds to higher wear loss of Si3N4 and the wear loss of PCD almost fell close to zero. Especially in the case of 85% RH, both a maximum wear loss of Si3N4 and a maximum friction coefficient were achieved. In addition, this study revealed insights into the interface chemistry effects on the wear behavior of Si3N4 under humidity. When water molecules were introduced into the testing atmosphere, the hydrolysis reaction occurred on the Si3N4 surface with the formation of the Si‐O‐Si bond across the sliding interface. And then, the hydration reaction dominated the process, during which Si‐OH was formed through the bond fracture of the Si‐O‐Si. The X‐ray photoelectron spectroscopy results showed that the ratios of Si‐OH/Si‐O and Si‐N/Si‐OH+Si‐O bonds increased as the relative RH levels increased. As a consequence, the wear loss of Si3N4 significantly increased. Thus, due to the hydrolysis and hydration reactions, the tribological behaviors of Si3N4 against sintered polycrystalline diamond can be essentially controlled via varying RH levels.

“…Surface mechanical attrition treatment (SMAT) can be used to apply repeated impacts on a sample surface and refine grains on the material surface [16,17] . But few investigations have been carried out to predict the effect of SMAT on corrosion behavior when using a 3.5 wt.% NaCl solution (the equivalent concentration of sea water).…”

“…However, the strong oxidizing property of hydrogen peroxide (H 2 O 2 ) determines the incompatibility and excessive wear of materials under the H 2 O 2 , which results in the decomposition of H 2 O 2 and premature failure of some parts of the propulsion engine [8,10]. The traditionally compatible metals of H 2 O 2 , pure aluminum and austenitic stainless steel, could not preserve enough wear resistance [11,12]. In order to achieve the stable and long-life operations of the hydrogen peroxide propulsion systems, it is urgent to develop the compatible and wear-resistant tribo-pair materials serviced in H 2 O 2 solution.…”
